Emergency room and hospital discharge data have been used to describe the risk factors and public health impact of dog bites. These data sets are based on financial charges for severe bites and underestimates dog bite burdens within communities. This study expands both the source of information and risk factor data collected to provide demographic analysis of dog bite injury risk factors reported in Bay County, Florida in 2009–2010. Extended data for dog bites reported by various sources from January 1, 2009 to December 31, 2010 were collected by Florida Department of Health in Bay County. Data collected included bite victim's age and gender, primary reported cause of bite, setting, dog's restraint status and relationship between the victim and the dog. A total of 799 bites were reported. Most bites (55%) were reported first by healthcare practitioners, particularly bites involving children <6 years. Bites involving unfamiliar dogs and dogs off the owner's property were more likely to be reported by other sources. Boys aged 6–14 years accounted for 2.24 times more bites than same‐aged females (P < 0.001) and had the highest incidence with 424 bites per 100 000 persons per year. Persons 6 years or older were 3.6 times more likely to be bitten by an unfamiliar dog. Inappropriate behaviour management was the most common cause of bites (26%), followed by protective behaviour (24%). Bites of unknown cause were 2.5 times more likely in children <6 years. Separating dog fights was the most common cause of bites for persons 15 years or older (24%); females were significantly more likely to be bit than males (P = 0.01). Bites by unrestrained dogs off the owner's property (32% of all bites) most commonly involved males. Estimates based solely on healthcare discharge data significantly underestimate dog bite burden within a community. Characterizing these risks by age group or gender provides an opportunity to implement targeted interventions to prevent dog bites.  相似文献

Twenty prepubertal Yorkshire X Hampshire pigs were mixed in groups of four. Their behaviors were recorded on video tape for 48 h, and a detailed behavioral analysis was performed. Aggressive interactions of 10 unique pairs of pigs were observed. Twenty-five distinct behavioral categories were identified in the total data set, which contained 1,846 behaviors. On average, an interacting pair showed 92 behavioral elements (range: 10 to 307). Eighty-one percent of the behaviors observed consisted of bites and pushes given and received. Bites were targeted mainly at the ears (55%), face (17%) and neck (23%). Most bites to the rump and turning the body 180 degrees occurred during the last third of the fight. Pigs that eventually won fights showed higher incidences of ear bites and lower incidences than expected of head-under-head pushing and body-turning. Pigs that lost fights showed higher frequencies of head-under-head pushing and body-turning. Losers also showed a lower frequency of rump biting. Overall, many of the behaviors performed by the losing pigs were followed by the loser receiving an ear bite. Body-turning was a sign of submission and was always preceded by, and often followed, ear-biting. Once a pig showed body-turning, it generally avoided further face-to-face interaction. Behaviors exhibited as signs of submission were found in each of the 10 pairs observed.  相似文献

The issues surrounding dog bites are a major public health concern, particularly in areas of low income where accessibility to adequate health care, veterinary medicine and sufficient management of canine population control is low. An understanding of the risk factors associated with human-dog conflicts may be important when establishing dog bite and disease prevention strategies. In May 2008, a census of 12 consociated neighbourhoods in Todos Santos, Guatemala was conducted to investigate dog bite incidences and the public perception of free-roaming dog populations. Approximately 16.5% (78/472) of households reported at least one dog bite between May 2006 and May 2008. In total, 85 incidents occurred: 49.4% (42/85) with adults (≥18 years) and 50.6% (43/85) children (<18 years). However, there was no significant difference in cumulative incidence of dog bites by victim gender or among age categories, there was a non-significant trend of higher cumulative incidence of dog bites in children aged six to 17 years compared to other age categories. The anatomical location of the bite varied, but bites to the legs were the most common (73/85; 85.9%). Of the 85 reported dog bites, 5.9% (5/85) were from dogs from the victims' own households, 48.2% (41/85) were from a neighbour's dog, 9.4% (8/85) were from dogs regularly seen in the community, and 15.3% (13/85) were from dogs not regularly seen in the community; the ownership status of the latter two categories of dogs could not be determined. Approximately 21% (18/85) of respondents did not know the type of dog that bit. Residents were asked for their opinions on potential problems associated with dogs in the community. The majority of respondents strongly agreed that dogs posed physical risks (78.8%; 372/472), could transmit infections to people (88.6%; 418/472), scared the family (82.4%; 389/472) and were too high in number (82.6%; 390/472). There were significant but weak correlations between owning a dog and expressing negative perceptions of community dogs (Spearman rho<0.13). Reporting of a dog bite was not significantly correlated to expressing fear or negative perceptions towards community dogs. A further understanding of current programs directed at the prevention of dog bites and means of dog population control may help determine appropriate future steps for canine management. Conflicts between free roaming dogs and people are a pressing issue worldwide, and a focus on prevention strategies through education, rather than rapid extermination, would be of benefit.  相似文献

Bartonella henselae is the causative agent of cat scratch disease (CSD) in humans. Cats are the main reservoir of this bacterium and may infect humans through scratches and bites. The purpose of this study was to determine the B. henselae seroprevalence in cats in Turkey. A total of 298 cats blood samples were collected from six different provinces of Turkey. Sera were tested for the presence of anti-B. henselae IgG antibodies by indirect fluorescent antibody test (IFA). The seroprevalence of B. henselae was 27.9% (83/298) for the cats examined in this study. The seroprevalence of cats by province was significantly higher in Bursa (41.3%), Adana (33.9%), Aydin (27.5%) and Burdur (32.3%) than in Kayseri (17.9%) and Istanbul (12.5%). Statistically significant differences were not observed between cat sexes and living conditions of cats. The results revealed that B. henselae is an important zoonotic pathogen in Turkey.  相似文献

Postmortem examinations were carried out on 379 otters found dead in southern and south-west England between 1988 and 2003. Most (81 per cent) were road casualties, but many had open bite wounds and in some cases these had proved fatal. Mortality was strongly seasonal and was positively correlated with night length. Although numbers decreased in the summer months, the prevalence of bite wounds in adults was highest in late summer. The number of otters examined annually and the prevalence of bite wounds increased markedly during the study period, and in 2003 more than half the otters of both sexes had recent bite wounds. The majority of the bites were considered to have been caused by other otters, but some were thought to have been inflicted by American mink (Mustela vison). Bites to cubs were mostly caused by domestic dogs. The overall mortality due to bite wounds was approximately 10 per cent.  相似文献

Various measures, including ticketing, licensing, and breed-specific legislation, are used by municipalities to control dog bites, but their effectiveness is largely unknown. Thirty-six urban Canadian municipalities provided information about their animal control practices, resourcing, and (for 22 municipalities) rate of reported dog bites. Municipalities differed widely in rates of licensing (4% to 75%) and ticketing (0.1 to 83 per 10 000 people), even where staffing and budgets were similar. Reported frequency of dog bites ranged from 0 to 9.0 (median 1.9) per 10 000 people. Rates were generally higher in municipalities with higher ticketing, licensing, staffing, and budget levels. However, in municipalities with very active ticketing the reported bite rate was much lower than predicted by a linear regression on ticketing rate (quadratic regression, R2 = 0.52), likely reflecting a reduction in actual bites with very active enforcement. Municipalities with and without breed-specific legislation did not differ in reported bite rate. Ticketing appeared most effective in reducing dog bites, although it may also lead to increased reporting.  相似文献

Approximately four to five million animal bite wounds are reported in the USA each year. Domestic companion animals inflict the majority of these wounds. Although canine bites far outnumber feline bites, unlike the dog, the cat's bite is worse than its bark; 20-80% of all cat bites will become infected, compared with only 3-18% of dog bite wounds. Pasteurella multocida is the most commonly cultured bacterium from infected cat bite wounds. Anyone seeking medical attention for a cat-inflicted bite wound is given prophylactic/empiric penicillin or a derivative to prevent Pasteurella infection (provided they are not allergic to penicillins). In an effort to establish a carriage rate of P. multocida in the domestic feline, bacterial samples from the gingival margins of domestic northern Ohio cats (n=409) were cultured. Isolates were tested for antibiotic sensitivity as prophylactic/empiric use of penicillin and its derivatives could potentially give rise to antibiotic resistance in P. multocida. The high carriage rate (approximately 90%) of P. multocida observed was found to be independent of physiological and behavioural variables including age, breed, food type, gingival scale, lifestyle and sex. High antibiotic susceptibility percentages were observed for benzylpenicillin, amoxicillin-clavulanate, cefazolin, and azithromycin (100%, 100%, 98.37% and 94.02%, respectively) in P. multocida isolates. The high prevalence of P. multocida in the feline oral cavity indicates that prophylactic/empiric antibiotic therapy is still an appropriate response to cat bite wounds. Additionally, the susceptibility of P. multocida to penicillin and its derivatives indicates that they remain reliable choices for preventing and treating P. multocida infections.  相似文献

Tick bites on humans can occur in a variety of habitats and may result in the transmission of tick‐borne pathogens, such as the causative agent of Lyme borreliosis (LB), Borrelia burgdorferi sensu lato. As the risk of transmission of this pathogen to the host increases with the duration of tick feeding, the recognition and removal of ticks as soon as possible following attachment is important for reducing the risk of infection. Performing a thorough body examination for ticks following potential exposure is recommended by tick awareness campaigns. Knowledge of where on the body feeding ticks are frequently found, and at which times of year peak tick exposure occurs, provides important information for public health messaging and may aid those bitten by ticks to engage more effectively with tick‐checking behaviour. This paper summarizes human tick bites in the United Kingdom (UK) during 2013–2018 reported to Public Health England's passive Tick Surveillance Scheme and further examines the anatomical location and seasonality of bites from the most commonly encountered tick and LB vector Ixodes ricinus. A total of 1,328 tick records from humans were received of which 93% were I. ricinus. Humans were most commonly bitten by I. ricinus nymphs (70% bites). Tick bites were recorded on all parts of the body, but there were significant differences in their anatomical location on adults and children. Most tick bites on adults occurred on the legs (50%), whereas on children tick bites were mostly on the head and neck (43%). Bites from I. ricinus were recorded throughout the year but were most numerous during May to August. This study adds to the body of research on the seasonality and anatomical location of human tick bites in temperate Europe and highlights the importance of data collected through passive surveillance in addition to research and epidemiological studies.  相似文献

In order to evaluate the degree of adaptability of three native cattle breeds to the natural pastures of southern Italy, the diurnal grazing behavioural pattern was monitored on 84 multiparous cows: 28 Podolian (14 suckling and 14 non-suckling), 28 Chianina (14 suckling and 14 non-suckling) and 28 Romagnola (14 suckling and 14 non-suckling). From August to October 2009 ten sessions of 9 h of behavioural observations were performed, from 07.00 to 19.00 h, through continuous focal animal recording method. Every hour, bite rate was recorded and bite mass and botanical preferences were determined on hand-plucked samples. Chianina cows selected proportionally more percent legumes than Romagnola and Podolian animals (P < 0.01), whereas Podolian cows chose a higher percentage of ferns (P < 0.05). Grasses represented a large proportion of the diet ingested by cows; these plant species were predominantly ingested in a late stage of maturation, which, in turn, induced the animals to take larger bites. Conversely, bite rate was positively related to high quality forages and negatively related to bite mass. Due to low genetic diversity and “allelo-mimetic” behaviour, no marked differences were observed among Chianina, Romagnola and Podolian breeds in terms of activity budget, ingestive behaviour and chemical composition of the diet as assessed through hand plucking. Based on rough estimations, all three breeds were able to reach the minimum ingestion levels needed to cover their maintenance and productive requirements of energy and protein. The three genotypes spent most of their time on grazing activity, followed by walking, whereas less time was spent resting. Animals were more active during mornings and afternoons in terms of grazing and walking (P < 0.05). Vocalizations were not influenced by breed but were significantly more frequent in cows with calf (4–5 months of age) than in non-suckling animals (P < 0.001). The presence of calf had no significant effect on the other behavioural variables. Cows from different breeds expressed preferential spatial relationships with other members of the herd. These results along with the low levels of agonistic and non-agonistic interactions occurring between herd-mates suggest that extensive systems based on grazing allow social stability, expression of species-specific behaviours and fulfilment of maintenance and productive requirements of cows from native breeds.  相似文献

Objective To determine the extent of the snake bite problem in domestic animals, its regional significance and the effects of antivenom treatment.
Design A questionnaire was designed seeking information on the number and type of domestic animals referred, whether treated or untreated, type of snakes and management of the bite.
Procedure The survey form was sent to 10% of veterinary surgeons, selected at random throughout Australia.
Results The response of 106 veterinary surgeons revealed that snake bite in domestic animals is frequent, with an estimated 6200 cases reported annually. Bites were more prominent in rural (78%) than urban areas (22%) with brown, tiger and black snakes accounting for 76%, 13% and 6% of cases, respectively. Cats and dogs were the most frequently reported victims. Ninety-one percent of cats and 75% of dogs survived following the administration of antivenom whereas 66% of cats and 31% of dogs survived without antivenom. Overall, in 33% of cases antivenom was not used, and venom detection kits were used in only 1% of cases. A number of drugs were used in various combinations with or without antivenom and intravenous fluids in the treatment of animals with snake bite, but their role in reducing the severity of envenomations was not assessed.
Clinical implications Antivenom significantly improves the chances of survival of domestic animals bitten by snakes.  相似文献

AIM: To investigate the circumstances of dogs biting people in New Zealand.

METHODS: Veterinary science and veterinary nursing students enrolled at Massey University in 2003 completed a questionnaire detailing their lifetime experience of dog bites and their opinions of dog control legislation.

RESULTS: The response rate was 100%. There were 228 completed responses to the survey, and 87 (38%) respondents had been bitten by a dog. Most bites caused minor injury, but 17 (20%) required medical attention. Male respondents were more likely to have been bitten. The highest proportion of respondents (27; 31%) had been bitten while between 6 and 10 years of age, and the hand was the part of the body most often injured. Eighteen (21%) bites involved a stranger's dog, but most bites were by a dog known to the victim. Respondents from rural areas were three times more likely to have been bitten than city dwellers. The victim's home was the place where most (31; 36%) bites occurred. Male dogs were responsible for a larger proportion of bites (38; 44%) than females (24; 28%); respondents were unsure about the sex of the remainder of the dogs (25; 29%) that bit them. Protecting the home, play, accidents, rough handling and pain were identified as the common reasons for dogs to bite. Most (46; 52%) respondents did not believe legislation could have prevented their bite. Only four (5%) bites were reported to authorities.

CONCLUSION: Rural dwellers, people with more experience of dogs, children <11 years of age, and male respondents were bitten by dogs most often. Only legislation relating to the fencing of dog owners′ properties may have prevented a reasonable proportion (25; 29%) of the bites reported here.  相似文献

Interviews to solicit information about animal bites and rabies vaccinations were completed on 1165 of 1175 non-military veterinarians in Illinois in 1968. Two hundred and sixty-one veterinarians reported 380 exposure incidents that precipitated the administration of rabies vaccine; 72 veterinarians had received two or more series of vaccine. Vaccine was administered after exposure from: examination of a patient (n = 230), bite (n = 79), necropsy (n = 17), other causes (n = 13) and unstated (n = 41). Eighty-six percent of the exposures were to dogs or cattle. In 231 veterinarians receiving postexposure vaccinations, where year of first vaccination and year of graduation from veterinary school were known, 97 (42%) were exposed in the six years spanning one year before graduation and four years after graduation. There were 296 veterinarians, including 12 receiving postexposure vaccination, who had received their first series of vaccine as preexposure prophylaxis. Twenty-one percent of all vaccinees (pre- and postexposure) reported reactions to the rabies vaccine. Seventy-two veterinarians reported they had been treated for an animal bite in the previous year.  相似文献

Native pastures that present high botanical richness produce a variety of feed items for grazing herbivores. Diet selection takes place at the bite scale and, at a daily scale, the sum of bites composing the intake determines diet characteristics. The objective of this paper is to bring an original contribution to the understanding of diet selection in diverse foraging environments such as native Pampa grasslands. The issues are 1) to improve grazing management in Pampa ecosystems and 2) to evaluate the ability of native pastures to feed a herd in order to reduce supplementation and to improve the economic sustainability of extensive systems. We hypothesize that the information contained in the infrared spectra of plant samples corresponding to potential bites can be useful for establishing functional bite categories, which, in turn, can be used to understand and manage pastoral ecosystems. We analyzed the near-infrared spectrum (NIRS) of 1 515 bite samples gathered in 2012 using the continuous bite monitoring method applied to heifers continuously grazing on Pampa grassland at five grazing intensities (randomized block design with two replicates, applied since 1987). On the basis of the main wavelengths, a statistical classification of bite samples was produced and five classes were described: 1) small bites of wetland grasses and short grass; 2) medium bites of forbs and short grass; 3) small bites of short Poaceae and mixed species; 4) large bites on tussocks of Poaceae; and 5) extralarge bites on stiff tussock of Poaceae and Apiaceae. In order to evaluate the functional value of the classification, we tested its ability to take seasonal changes in pasture composition into account and to describe the variations in animal intake and performance in contrasted grazing conditions. We concluded that the NIRS is a good support for establishing functional classes of feed items that can be used to understand the foraging behavior and diet composition of grazing herbivores. Our approach was tested in Pampa grasslands grazed by cattle but should be applicable to a wide range of ecosystems, provided that chemical composition is more relevant for selection than feed item accessibility.  相似文献

In order to assess the Rhodococcus equi infection in three provinces of Turkey (Bursa, Izmir and Istanbul), 696 sera from healthy foals and adult horses were tested by indirect ELISA using a R. equi reference strain (ATCC 6939) as antigen. 103 sera (14.80%) with titres >0.646 resulted positive. Seroprevalence was significantly higher (P=0.0053) in male than in female horses of Istanbul province, although higher antibody titres (mean value) were observed in the female group of Bursa and Izmir provinces with differences estimated between provinces (P=0.0002). Seroprevalence was correlated with age: foals aged less than 1 year (P<10(-4)) and horses from 5 to 10 years old (P=0.018) resulted more infected in Bursa and Izmir provinces. Our findings indicate that R. equi infection actually occurs in all investigated provinces, suggesting the importance of serological survey to diagnose the infection and to prevent the zoonotic risk.  相似文献

OBJECTIVES: To understand the epidemiology of animal bites and exposure, evaluate the animal exposure reporting system for surveillance of rabies postexposure prophylaxis (PEP), and identify opportunities to reduce PEP. DESIGN: Period prevalence survey. STUDY POPULATION: Pennsylvania residents in 1995. PROCEDURE: Data from animal bite reports from Pennsylvania county health offices were summarized for 1995. Animal bite incidences for the state, counties, various age groups, and various population densities were calculated. Animal species, treatment, location of wounds, and PEP recommendations were evaluated for exposures. RESULTS: More than 16,000 animal-related potential rabies exposures were reported from 65 of 67 counties in Pennsylvania. The highest incidence was in children less than 5 years old (324/100,000). Of the 75% of victims requiring wound treatment, 50% received antimicrobials, 29% received a tetanus toxoid, and 19% had wounds sutured, were admitted to hospitals, or were referred for plastic surgery. Although 75% of exposures were to dogs, victims exposed to cats were 6 times as likely to receive PEP (relative risk, 6.1; 95% confidence interval, 5.1 to 7.4). Thirty percent of 556 PEP were given for exposures to dogs, 44% for cats, 7% for raccoons, 4% for bats, 2.5% for squirrels, 2.1% for groundhogs, 2% for foxes, and 8% for exposures to other species. Fifty-nine percent of owned dogs were up-to-date on rabies vaccinations compared with 41% of owned cats. CONCLUSION: Interventions, such as dog bite prevention education, vaccination of pets against rabies, appropriate use of PEP, and reduction of feral cat populations, should be instituted, enhanced, or better enforced in communities.  相似文献
