Kenya has the highest reported incidence of human hydatid disease in the world. Up to about 30% of cattle, 15% of goats and 13% of sheep harbour the infection. The causative agent of the disease in Kenya is Echinococcus granulosus and a complex strain picture of this parasite has been postulated to occur. The domestic dog is the main definitive host of E. granulosus in Kenya but infection in wild carnivores has also been reported. Hydatid cysts have also been found in wild herbivores. Although the domestic cycle has been shown to be the most important mode of transmission of the disease, a sylvatic cycle is also known to exist. The etiology of hydatid disease, the strain differentiation of E. granulosus found in Kenya, and the role that wildlife plays in the transmission cycle is reviewed. The current trends in the incidence of hydatid disease in man and livestock, and the efforts being made to control the disease are also discussed.  相似文献

AIM: To investigate the seroprevalence of Neospora caninum infection in populations of dogs from dairy farms, sheep/beef farms and urban areas in the central part of New Zealand. It was postulated seroprevalence would be higher for farm dogs than urban dogs if the life-cycle of this parasite involves transmission between dogs and cattle. METHODS: Serum samples were obtained from dogs that lived on dairy farms (n=161), sheep/beef farms (n=154) and in urban situations (n=150). The relative risk of detecting antibodies to N. caninum using an immunofluorescent antibody test (IFAT) was compared between farm and urban dogs. RESULTS: The relative risk of having a titre of > or = 1:200 to N. caninum was 2.43 (95% CI=1.88-3.14) for dairy-farm dogs and 3.16 (95% CI=2.48-4.02) for sheep/beef-farm dogs, compared with urban dogs. At this titre, which is currently used in New Zealand to indicate seropositivity, seroprevalence of N. caninum infection was 30.7% in urban dogs, 74.5% in dairy-farm dogs and 96.8% in sheep/beef-farm dogs. CONCLUSION: This observation is consistent with a cycling of this disease between cattle and dogs on farms in New Zealand and with higher exposure of dogs to N. caninum on farms than occurs in urban environments. The prevalence of antibodies in all three groups of dogs tested in this study (dairy-farm dogs, sheep/beef-farm dogs and urban dogs) is higher than has generally been reported elsewhere. New Zealand farm dogs have a higher serological prevalence of N. caninum infection than urban dogs. CLINICAL RELEVANCE: Management and disease control practices that break the life-cycle of transmission between cattle and dogs should assist in controlling cattle abortion due to N. caninum.  相似文献

There was an 8-fold increase in the national prevalence of Taenia ovis in dogs during the first decade of the New Zealand hydatid disease control program. The temporal patterns in the prevalence of T. ovis were similar in both rural working dogs and urban pet dogs, with the highest prevalence found in the sheep farming areas. The dramatic increase in the prevalence of T. ovis was a reflection of the change in source of food for many working dogs, from the traditional raw viscera to carcase meat of sheep, a change necessitated by hydatid disease control. Other factors influencing the rise in prevalence of T. ovis in rural dogs were investigated using stepwise multiple regression techniques. The results of the regression analyses suggested that the rate of increase in the prevalence of T. ovis was influenced by 4 major factors: Taenia hydatigena variables (initial prevalence and rate of progress in control), an ethnic variable (Maori proportion in local population), canine variables (numbers of dogs per farm and per owner), and animal husbandry variables (pasture type, sheep density and numbers of sheep per farm). The results were discussed in the light of present knowledge of the epidemiology and immunology of the taeniid cestodes.  相似文献

In the present study, 115 stray dogs (56 males and 59 females, mixed breed), 86 golden jackal (Canis aureus, 42 males and 44 females), 60 red foxes (Vulpes vulpes, 33 males and 27 females), and three female wolves (Canis lupus) were examined for Echinococcus granulosus infection, as well as, 32,898 sheep, 10,691 goats, 15,779 cattle and 659 buffaloes for hydatid infection from five provinces in western Iran during 3 years (1997-2000). Meanwhile fertility rates of different types and forms of cysts isolated from infected animals and the viability of protoscolices were also determined. Results indicated that 19.1% of the dogs, 2.3% of the golden jackals and 5% of the red foxes were infected with Echinococcus granulosus. 11.1% of the sheep, 6.3% of the goats, 16.4% of the cattle and 12.4% of the buffaloes were also found to be infected with hydatid cyst. The cysts isolated from liver and lungs of the sheep show higher fertility rate than the cysts of liver and lungs of goats, cattle and buffaloes.  相似文献

A study on the prevalence of hydatidosis in cattle, goats and sheep was carried out in Ngorongoro district of Arusha region, Tanzania. A 4-years data records from four slaughter slabs were retrieved and analysed. In addition, meat inspection was done in the same slaughter slabs for nine months and 64 households were interviewed to assess the community awareness on hydatidosis. Results showed the overall prevalence of hydatidosis to be 47.9%. Species prevalence of 48.7%, 34.7% and 63.8% in cattle, goats and sheep respectively was recorded. Of 174 cysts examined in cattle, 37 (21.3%) were fertile, 126 (72.4%) were sterile and 11 (6.3%) were calcified. Out of 215 goats and 67 sheep cysts examined, 52 (24.7%) and 26 (38.8%) were fertile, 138 (64.2%) and 38 (56.7%) were sterile, 24 (11.2%) and 3 (4.5%) were calcified respectively. The higher percentage of fertile hydatid cysts in sheep and goats coupled with the practice of backyard slaughter of sheep and goats suggests that, these animals could be important intermediate hosts for the maintenance of the domestic life cycle of E. granulosus in the locality. Questionnaire survey revealed that 17.2% of the respondents were aware of hydatidosis but non of them were knowledgeable on its transmission. Up to 84.4% of the respondents had domestic ruminants and donkeys, while 89.1% had dogs. Of the households with dogs, only 19.3% had their dogs dewormed at least once in life time. Most of the households (87.7%) had their dogs managed freely and 77.2% of the respondents reported school children to be the closest friends of dogs in the family. The prevalence of E. granulosus infection in wildlife and the possible relationship of the domestic cycle to the sylvatic cycle operating in the same area are unknown and need to be studied.  相似文献

Meat inspection records in an abattoir located in Shiraz, a city in southwest Iran and the capital of Fars province, during a 5-year period from 20 March 1999 to 19 March 2004 were used to determine the prevalence of hydatidosis in sheep, cattle, and goats in the region. A total of 844,039 animals (cattle 131,716; sheep 577,090; goats 135,233) slaughtered in the 5-year period and overall 34,856 (4.1%) livers and 123,402 (14.62%) lungs were condemned. Hydatidosis was responsible for 28.7 and 15.4% of total livers and lungs condemnations, respectively. The overall trend for all livestock and in both organs was a significant downward one. The annual prevalence of liver condemnations due to hydatidosis was decreased from 2.1, 1.8, and 1.0% in 1999-2000 to 0.62, 0.33, and 0.20% in 2003-2004 for cattle, sheep, and goats, respectively. The corresponding features for lung condemnation due to hydatidosis were relatively higher than liver, declining from 3.0, 4.6, and 4.4% in 1999-2000 to 1.3, 1.5, and 0.56% in 2003-2004, for cattle, sheep, and goats, respectively. Greater awareness among farmers, destruction of organs containing hydatid cysts, prevention of access of dogs to raw offals and implementation of national rabies control program could be responsible factors. Data showed significant seasonal pattern for hydatidosis in all species. Liver condemnations due to hydatidosis were higher in the spring and summer for sheep, whereas lung condemnations were higher in summer for both sheep and goats. Liver and lung condemnations in cattle were higher in winter. This could be attributed to various factors such as sources of slaughtered animals, changes in management practice and ecological factors. The overall trend was relatively the same when annual condemnations were adjusted for the effect of seasonal variation. The present survey provides baseline data for the future monitoring of this potentially important parasitic disease in the region.  相似文献

The distribution of livestock in Cyprus was described and analyzed by contingency table methods. Smaller numbers of sheep, goats and cattle were associated with Greek Cypriot villages. Sheep and goat densities were highest in Turkish Cypriot villages. Among the villages in which the slaughter of livestock was reported, the median percent prevalence of hydatid cysts was: 16.5% (range: 0–100%) in slaughtered sheep; 2.1% (0–100%) in slaughtered goats; 0.0% (0–100%) in slaughtered cattle; 0.0% (0–33%) in slaughtered pigs. The median numbers of livestock slaughtered in villages for the 6-month period were 45 sheep, 98 goats, 4 cattle and 32 pigs. The association between the prevalence of Echinococcus granulosus in the slaughtered sheep population (SHPPREV) of 254 villages of Cyprus and human, canine, and environmental factors, for the period June–December, 1972, was analyzed by step-wise multiple regression. Results showed that 25% of the total variation in SHPPREV was explained by 3 independent variables, total rainfall from the previous 6-month period (negatively correlated with SHPPREV), E. granulosus prevalence in dogs (positively correlated) and the percent village population composed of Turkish Cypriots (negatively correlated). Total rainfall from the previous 6-months period, alone, explained 19% of the total variation.  相似文献
