OBJECTIVES: To provide basic information about natural feline osteoarthritis (OA) as part of more extensive studies. METHODS: A retrospective study of cats (greater than one year of age) radiographed for any reason at a first opinion and referral veterinary practice was performed. Cats were classified as either having or not having radiographic OA. Computerised histories were searched for records of potential causes and clinical signs of OA. The genders and ages of the affected cats were compared with a control population using chi-squared tests. RESULTS: Of 491 cats, 292 (59 per cent) had undergone a diagnostic radiograph of at least one synovial joint. Sixty-three of 292 cats (22 per cent) showed evidence of radiographic OA; 21 (33 per cent) of which also had clinically evident OA. A potential cause of OA had been recorded in only seven of 63 cats (11 per cent). The population of cats with radiographic evidence of OA was older than the control population (P<0.001). CLINICAL SIGNIFICANCE: Radiographic OA was found in 22 per cent of the test population. In many cases there was no clinical evidence of OA recorded in the history, suggesting that either there is little correlation between clinical and radiographic OA or that clinical signs of OA in cats may not have been observed or recorded. Idiopathic/primary OA was common.  相似文献

Two visits, six weeks apart, were made to a cat rescue shelter and single oropharyngeal swabs were taken from all the compliant cats. Feline calicivirus was isolated from 14 of 45 swabs (31 per cent) taken on the first visit and 12 of 46 swabs (26 per cent) taken on the second visit. Nucleotide sequences were obtained for nine isolates from the first visit, six isolates from the second visit, and for the vaccine virus used in the cattery. Distance analysis showed that the majority of the isolates could be assigned to one of two groups. All the isolates obtained from cats sharing the same pen or isolates obtained from the same cat on successive visits, were less than 5 per cent distant, whereas most of the isolates from cats in different pens were more than 20 per cent distant. Phylogenetic analysis showed that at least seven distinct field isolates were present in the cattery. The only good evidence for virus transmission within the cattery was a case in which two viruses isolated from cats in different pens had sequences that were less than 5 per cent distant.  相似文献

A representative sample of the pet cat population of the United Kingdom was surveyed. Blood samples from 1204 sick and 1007 healthy cats of known breed, age and sex were tested for antibodies to feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV). The prevalence of FIV was 19 per cent in sick cats and 6 per cent in healthy cats, and the prevalence of FeLV was 18 per cent in sick cats and 5 per cent in healthy cats; both infections were more common in domestic cats than in pedigree cats. Feline immunodeficiency virus was more prevalent in older cats but FeLV was more prevalent in younger cats. There was no difference between the prevalence of FeLV in male and female cats but male cats were more likely to be infected with FIV than female cats. No interaction was demonstrated between FIV and FeLV infections. Of the cats which were in contact with FIV in households with more than one cat, 21 per cent had seroconverted. The prevalence of FeLV viraemia in cats in contact with FeLV was 14 per cent. The clinical signs associated with FIV were pyrexia, gingivitis/stomatitis and respiratory signs, and with FeLV, pyrexia and anaemia. It was concluded that both viruses were significant causes of disease, and that the cats most likely to be infected with FIV were older, free-roaming male cats and for FeLV, younger, free-roaming cats.  相似文献

O bjective : To determine response to treatment, survival and prognostic factors for feline extranodal lymphoma in the UK.
M ethods : Records of cats diagnosed with lymphoma of extranodal sites at seven referral centres were reviewed and information on signalment, tumour location, prior treatment and chemotherapy protocol recorded. Factors influencing response to treatment and survival were assessed.
R esults : One hundred and forty-nine cases met inclusion criteria. Sixty-nine cats had nasal lymphoma, 35 renal, 15 central nervous system, 11 laryngeal and 19 miscellaneous locations. Sixty-six cats received cyclophosphamide, vincristine, prednisolone, 25 Wisconsin-Madison doxorubicin-containing multi-agent protocol, 10 prednisolone alone and nine other combinations. The response rate for the 110 treated cats was 85·5 per cent. Of cyclophosphamide, vincristine, prednisolone treated cats 72·7 per cent achieved complete remission, median survival 239 days. Sixty-four per cent of Wisconsin-Madison treated cats achieved complete remission, median survival 563 days. Cats with nasal lymphoma achieving complete remission had the longest survival (749 days) and cats with central nervous system lymphoma the shortest (70 days). If complete remission was achieved, prior treatment with corticosteroids significantly reduced survival time.
C linical S ignificance : Cats with extranodal lymphoma respond to chemotherapy and achieve survival times comparable to other locations. Corticosteroid pretreatment reduced survival time in cats achieving complete remission.  相似文献

O bjectives : To review aetiology, clinical signs and outcome of cats surgically treated for septic peritonitis (2000-2007).
M ethods : A retrospective study. Inclusion criteria were the identification of intracellular bacteria and degenerate neutrophils and/or a positive culture from abdominal fluid and exploratory coeliotomy. Aetiology, clinical signs, haematological and biochemical parameters, surgical treatment and outcome were recorded and analysed.
R esults : Twenty-six cats fulfilled the inclusion criteria. Abdominal pain was reported in 10 (38 per cent) and vomiting was reported in 11 (42 per cent) of the cats. The most common aetiology was trauma (31 per cent). The principal source of contamination was the gastrointestinal tract. Hyperlactataemia, hypoproteinaemia and hyperglycaemia were reported in 9, 13 and 14 of the 26 cases, respectively. Non-survivors had significantly higher blood lactate concentrations than survivors (P=0·02). Nineteen cats were managed with primary closure, two with closed suction drains and three with open peritoneal drainage. Twelve (46 per cent) cats survived to discharge.
C linical S ignificance : In cats, lethargy, depression and anorexia were more common clinical signs than abdominal pain. Lactate level at the time of diagnosis may be a useful prognostic indicator in cats. The proportion of cats that survived was lower than previously reported and owners should be given a guarded prognosis.  相似文献

Comparative net digestive and absorptive efficiency was assessed with adult Beagles and domestic cats by apparent digestibility assays. Eight foods were used comprising two canned dog foods; canned cat foods; two samples of semipurified diet; and single samples of experimental dry cat food and fresh mince. Apparent digestibility percentages of crude protein, fat, nitrogen-free extract (NFE) and gross energy were all significantly higher in dogs than cats. Mean values obtained for dogs were (per cent): crude protein 87; fat 92; NFE 70 and energy 89. Respective values for cats were 82, 76, 67 and 79. On average, dogs obtained 11 and 9 per cent more digestible energy and protein per unit food eaten than cats. Most digestibility characteristics of foods measured in cats were significantly correlated with those for dogs and regression equations are presented predicting digestibility in cats from dog data.  相似文献

classification scheme for sacral fractures was based on a review of sacral fractures in 34 dogs and 17 cats. They were classified into five categories based on their radiographic appearance on standard lateral and ventrodorsal radiographs of the pelvis. Concomitant pelvic injuries were commonly observed: 32 per cent of dogs had a fracture of an ilium and 65 per cent of cats had unior bilateral sacroiliac subluxation. Neurological deficits were common where the fractures traversed the spinal canal or sacral foraminae. Comparison is made between sacral fractures in dogs and cats, and humans.  相似文献

The effects of ovariohysterectomy on bodyweight, composition and condition score were evaluated in 49 cats that were fed ad libitum and 11 cats that had their food allowances controlled with the aim of maintaining a stable bodyweight. In cats fed ad libitum, bodyweight increased by an average of 31 per cent in the 12 months following ovariohysterectomy compared with 3.1 per cent over the 12 months before surgery, and this was largely due to increased body fat content. There was no difference in weight gain between cats fed dry or canned foods, but weight gain was inversely related to age and bodyweight at the time of neutering. Mean bodyweight increased by 7.5 per cent in the controlled feeding group, compared with 3.6 per cent over the 12 months before surgery, and individual bodyweights were maintained to within 10 per cent of pre-neutering values in nine cats. The other two cats experienced substantial weight gain (+20 per cent and +36 per cent), despite being fed only 40 kcal/kg/day. There were no significant changes in body composition of cats with controlled dietary allowances and their condition scores were significantly lower than those of cats fed ad libitum. The results confirm a link between ovariohysterectomy and the development of obesity in cats with free access to food, and indicate that substantial reductions in energy intake are required to prevent weight gain in such cats.  相似文献

The medical records of 12 cats presented with intussusception and diagnosed at the University of Sydney Veterinary Teaching Hospital and the Sylvania Veterinary Hospital were reviewed. Eleven cats were less than one year old at the time of diagnosis. No breed or sex predilections were determined. The most consistent clinical signs were anorexia (83 per cent), weight loss (83 per cent) and a palpable abdominal mass (92 per cent). Vomiting (58 per cent) and diarrhoea (50 per cent) were seen less frequently in these cats compared with the reported incidence of these signs in dogs. In 10 cats the intussusception was corrected surgically. Manual reduction was successful in three of the cats but six required end-to-end anastomosis following intestinal resection and in one cat a typhlectomy was performed. Postoperative ileus complicated recovery in three cases. Recurrence of the intussusception at a different site occurred in two of these cases. One cat with recurrence of intussusception died and the cat with ileus but not recurrence was euthanased one month after the original surgery.  相似文献

Seventy-eight Turkish Van cats were examined for alloantibody titres, of which 42.3 per cent had type A blood and 57.7 per cent had type B blood. No type AB cats were found. All type B cats (n = 45) showed gross evidence of agglutinating anti-A antibody, with titres ranging from 2 to 256. Sixty-seven per cent of type B cats had anti-A antibody in their plasma, with titres ranging from 8 to 32. However, 13 per cent of type B cats had plasma alloantibody titres of less than 8 and 20 per cent had titres that were higher than 32. A total of 33 type A cats were also tested for anti-B alloantibody titres in their plasma. Among the type A plasma, gross agglutination at titres of 2 and greater than 2 were determined in 24 per cent and 36 per cent of samples, respectively. Microscopic agglutination was seen in an additional 18 per cent of plasma samples. There was no significant association between gender and plasma alloantibody titres of cats (P > 0.05).  相似文献

In a retrospective study of 155 cases of feline dystocia, 67-1 per cent were of maternal origin, mainly caused by uterine inertia, while 29-7 per cent were of fetal origin, mainly resulting from malpresentations/malorientations and deformities. Its breed incidence was somewhat higher in Persian cats than in other breeds and considerably lower in Norwegian forest cats. Litter size was not related to the risk of developing dystocia. Ninety-seven cats (62.5 per cent) were treated with calcium and, or, oxytocin. Medical treatment was successful in only 29 cases (29.9 per cent). Caesarean sections were performed on 123 (79.4 per cent) of the cats that were brought to the hospital because of dystocia. In 55 cases (35.5 per cent) a caesarean section was performed without prior attempts at medical treatment.  相似文献

Four cases of extrahepatic biliary tract surgery in the cat are described. The causes of the disease were inflammation of the gallbladder, distal common bile duct (CBD) or major duodenal papilla, and traumatic avulsion of the CBD. Bile peritonitis was present in two of the cats. Biliary enterostomy was performed in three cats, two of which were euthanased at five weeks and three months postsurgery; the third was alive at the time of writing, four months postsurgery. Cholecystectomy was curative in one cat. A literature review reveals high early mortality following biliary diversion, with only 50 per cent of cases surviving more than two weeks, and 23 per cent surviving more than six months. Surviving cats had repeated intermittent vomiting and anorexia that responded to antibiotics. No postoperative mortality was seen when biliary diversion was avoided. Whenever biliary enterostomy or temporary diversion methods are performed, a poorer prognosis should be offered due to the increased likelihood of postoperative complications and mortality.  相似文献

The clinical and radiographical features, and the results of treatment of 41 dogs and 10 cats with traumatic injuries of the spine are reviewed. There was a poor correlation between the degree of vertebral displacement and the neurological condition of the animals. Eighteen cases were treated conservatively, 16 were treated surgically and 17 were destroyed. Surgery was reserved for animals with either severe or progressive neurological dysfunction, and vertebral body plating and hemilaminectomy were the commonest procedures. Of the cases treated conservatively 94.4 per cent showed significant neurological improvement compared with 87.5 per cent of those treated surgically.  相似文献

OBJECTIVES: To determine the prevalence of blood types in the feline patients and blood donors of the Queen Mother Hospital for Animals (The Royal Veterinary College, London, UK), that were typed between 2000 and 2004. METHODS: A retrospective study was performed using files of patients and blood donors of the Queen Mother Hospital for Animals seen between January 2000 and November 2004. Commercial blood typing cards were used to determine the blood type. RESULTS: One hundred and fifty-six cats were included in the study; 51 (32.7 per cent) were pedigree and 105 (67.3 per cent) non-pedigree. Of the 51 pedigree cats, the prevalence of blood types was as follows: type A, 42 (82.4 per cent); type B, seven (13.7 per cent) and type AB, two (3.9 per cent). Of the 105 non-pedigree cats, the prevalence of blood types was as follows: type A, 71 (67.6 per cent); type B 32 (30.5 per cent) and type AB two (1.9 per cent). CLINICAL SIGNIFICANCE: The prevalence of type B blood in non-pedigree cats is higher than previously suggested and shows high variability within the UK; because of this, blood typing all feline patients, not only the ones of a breed typically known to have higher prevalence of type B blood before transfusion, is absolutely necessary to avoid a fatal transfusion reaction.  相似文献

Isolation rates of feline herpesvirus (FHV) and feline calicivirus (FCV) from oropharyngeal swabs, taken from 6866 cats in 1980 to 1989 were studied retrospectively. FCV was isolated from 1364 (19.9 per cent) and FHV from 285 (4.2 per cent). The ratio of FCV:FHV isolations varied from 1.3:1 to 15:1 in individual years with an overall ratio of 4.8:1. Isolation of both viruses was fairly uniform for each year and there was no breed or sex disposition to either virus. Of 872 cats shedding FCV and 213 cats shedding FHV, of known age, 447 (51.3 per cent) with FCV and 140 (65.7 per cent) with FHV were under one year old, compared to only 35.3 per cent of the whole population sampled. For the years 1985 to 1989, more information was obtained about the cases. Of 4626 cats tested, 1180 (25.5 per cent) had acute upper respiratory tract disease (URTD) of which 348 (29.5 per cent) were shedding FCV and 162 (13.7 per cent) FHV. A further 597 had chronic URTD and of these, 102 (17.1 per cent) were shedding FCV and 18 (3 per cent) FHV. In 120 cases of suspected vaccine reaction/breakdown, FCV was isolated from 34 (28.3 per cent) and FHV from only two (1.7 per cent). FHV was not isolated from any of 412 cases presenting with chronic gingivitis/stomatitis alone; 181 (43.9 per cent) were shedding FCV and when cats with other signs in addition to chronic gingivitis were included, this proportion increased to 70.4 per cent.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

A survey was made of the prevalence, diagnosis and treatment of dermatological conditions in small animals in general practice in the UK. Out of 3707 small animal consultations in general practice that were observed and recorded, 795 (21.4 per cent) involved animals that had a dermatological problem. In dogs and exotic species, pruritus was the most common presenting sign, accounting for 30 to 40 per cent of the dermatological consultations. In cats, cutaneous swellings were the most common presentation (36 per cent). A diagnosis or recommendation for treatment was made on the basis of the presenting clinical signs and physical examination alone in 576 (72 per cent) of the cases, and various diagnostic tests were performed in the other cases. In dogs, parasitic infestations, bacterial infections and neoplasia accounted for the majority of the diagnoses. In cats, parasites and bacterial infections were the most common. In exotic species, parasites accounted for over 80 per cent of the dermatological diagnoses. In dogs, the most common final diagnoses were otitis, pyoderma, anal sac impaction, flea infestation and atopic dermatitis. In cats, abscesses, flea infestation, and otitis were the most common diagnoses. In exotic species, the most common diagnosis was an unspecified mite infestation. Systemic antibiotics were prescribed in 196 cases (25 per cent), systemic glucocorticoids were prescribed in 162 cases (20 per cent) and treatment with an ectoparasiticide was prescribed in 167 cases (21 per cent).  相似文献

Records of all cats that had undergone exploratory coeliotomy at the University of Edinburgh during the period November 1995 to July 2002 were reviewed. Seventy records were retrieved. There were 30 cats in which infection or inflammatory disorders predominated, 17 cats with neoplasia, three cats with trauma and 20 cats with other disorders. Exploratory coeliotomy was performed for diagnostic purposes in 28 cats (40 per cent), treatment in 34 cats (49 per cent) and for diagnosis and treatment in eight cats (11 per cent). Methods of intraoperative diagnosis included incisional biopsy of abdominal organs (52 cats), cytology (two cats), microbiology (17 cats) and gross appearance (17 cats). Fifty-eight cats (83 per cent) survived the hospitalisation period. Complications occurred in 18 cats (26 per cent) and were related to anaesthesia (four cats), the underlying disease process (15 cats), surgery (five cats) and were undetermined in one cat.  相似文献

From 1984 to 1991, 22 cats with megacolon underwent colectomy by end-to-end anastomosis of the distal colon to either the proximal colon (preserving the ileocolic junction in 14 cats) or to the distal small intestine (excising the ileocolic junction in eight cats). During the postoperative adaptive period, the two groups showed similar stool consistency, and the presence of either anorexia, lethargy, weight loss or diarrhoea with faecal incontinence. During the long term post-operative adaptive period, no significant difference in recurrent constipation was found between the two groups. The overall constipation rate after colectomy was 45 per cent (10 cats), and because of constipation recurrence 18 per cent (four cats) were euthanased, and 18 per cent (four cats) required further surgery. Long term following colectomy, those cats which under-went excision of the ileocolic junction had significantly looser stools than those cats in which the ileocolic junction was preserved. The preservation of the ileocolic junction during colectomy is therefore recommended.  相似文献

During 2005, 31 uk veterinary practices participated in a survey of flea infestation, during which 2653 dogs and 1508 cats were examined for evidence of flea infestation and skin disease compatible with flea allergy dermatitis (fad). The prevalence of flea infestation in the cats was 21.09 per cent, significantly (P<0.001) higher than in the dogs (6.82 per cent). The prevalence of skin lesions compatible with fad in the cats (8.02 per cent) was also significantly (P<0.001) higher than in the dogs (3.32 per cent). Flea infestations were more common in households with cats and with more than one pet. Of 467 fleas identified from the cats, 462 (98.93 per cent) were Ctenocephalides felis, one was Ctenocephalides canis, one was Archaeopsylla erinacei, two were Pulex irritans, and one was Spilopsyllus cuniculi. Of 336 fleas identified from the dogs, 313 (93.15 per cent) were C felis, five were C Canis, 12 were A erinacei, five were P irritans, and one was Ceratophyllus (Nosophyllus) fasciatus. Almost half of the owners of the dogs and cats were unaware of their pet's flea infestation. The overall prevalence of fleas and/or skin lesions that could potentially be compatible with fad was 7.46 per cent in the dogs and 22.28 per cent in the cats.  相似文献

Three hundred and forty-six serum samples taken between 1998 and 2000 from urban stray cats in the city of Ghent were tested for antibodies to Toxoplasma gondii and feline immunodeficiency virus (FIV), and antigens of feline leukemia virus (FeLV). Of these 346 samples, 243 (70.2 per cent) were seropositive for Tgondii. Thirty-nine cats (11.3 per cent) had antibodies against FIV and 13 (3.8 per cent) had circulating antigens of FeLV. Fewer of the female cats had FIV and heavier cats had a higher seroprevalence of FIV. Exact logistic regression showed that cats that were infected with FIV were more likely to be infected with T gondii (P = 0.04), and the cats with FIV had a higher titre of Tgondii antibodies than FIV-negative animals. However, FeLV was not associated with either T gondii or FIV.  相似文献
