Prevalence of coccidia in beef cattle in western Turkey

A total of 504 bovine faecal samples collected from intensively managed beef farms in Afyon province of Turkey were examined to determine the types and prevalence of coccidian parasites present. Coccidian oocysts were found in 20.04% of all the samples examined by sucrose-flotation. The species detected and their prevalence were Eimeria bovis (34.55%), E. auburnensis (23.03%), E. canadensis (14.55%), E. brasiliensis (10.91%), E. zuernii (6.67%), E. bukidnonensis (3.03%), E. cylindrica (2.42%), E. ellipsoidalis (1.21%), E. illinoisensis (1.21%), E. alabamensis (1.21%) and Isospora sp. (1.21%). Mixed infections of two to four species were found in 43.6% of the animals. The overall prevalence of coccidial oocysts in faecal samples was 27.23% for calves, 15.65% for cows. Linear regression analysis showed that there is a significant reduction in the OPG (the number of oocysts per gram of feces) levels (P < 0.05) in cows infected with Eimeria. No cases of clinical coccidiosis were observed in this survey.

Dirofilaria immitis infection in dogs: unusually located and unusual findings

Clinical, blood, serum biochemistry, and parasitological assessments were performed on four hospitalized dogs, not in good general condition, in a study carried out to determine the prevalence of general parasitic infections. Hematological and biochemical parameters and electrocardiographic recording of the animals were determined during the general clinical examinations. Four dogs were indicated to have been infected with Dirofilaria immitis by using modified Knott’s method, and the microfilarial density was determined. Mild to moderate anemia and decrease in sedimentation velocity were established in dogs. Differences in other hematological and biochemical values between the dogs were determined. Right axis deviation was determined in a dog. D. immitis was encountered in the right ventricle, bronchus, and the pericardial sac at the end of the necropsy. On the other hand, in the histopathological examinations, pulmonary adenocarcinoma deriving from bronchial epithelium was identified in a dog, and microfilaria was encountered in bronchial and bronchiolar lumens, interstitium of the lungs, and bile ducts. D. immitis has not been considered in the diagnosis of dogs with pneumonia and tumors. The requirement of parasitological examination with respect to D. immitis in the diagnosis of dogs with tumor or pneumonia has been considered vital.

The acute effects of single-dose orally administered doramectin, eprinomectin and selamectin on natural infections of Syphacia muris in rats

This study was designed to determine the acute effects of a single-dose of orally administered doramectin, eprinomectin and selamectin on Syphacia muris infection in rats. Rats, naturally infected with S. muris, were divided into four groups: three different treatment groups (n=7) and one positive control (n=7). Cellophane tape preparations were obtained from the treated rats on day 0 pre-treatment and on days 2, 4 and 6 post-treatment. Syphacia sp. eggs were counted. Eprinomectin was found to be 100% effective in eliminating eggs on two post-treatment. However when egg counts on day 6 post-treatment were compared with pre-treatment egg counts, doramectin and selamectin were found to be 99.32 and 98.77% effective in eliminating eggs, respectively. On day 7 post-treatment, blood samples were obtained from all groups, and then the rats were necropsied. Doramectin, eprinomectin and selamectin were found to be 100% effective in eliminating adult S. muris, when compared with the positive control group.

Cysticercus bovis in Turkey and its importance from the public health aspect

This study was conducted in order to compare the different regions according to the literature on the prevalence of bovine cysticercosis and T. saginata in Turkey. Bovine cysticercosis and T. saginata status were evaluated retrospectively. The distribution of the data obtained according to provinces and regions were showed in the Table and the minumum / maximum values of this data in different regions in the Figure. The data obtained through the literature showed that the prevalence of C. bovis and T. saginata infections are parallel in the same region. The higher prevalence of both C. bovis and T. saginata infections was determined in the Southeastern Anatolia, Eastern Anatolia and Central Anatolia regions respectively.

Checklist of small ruminant gastrointestinal nematodes and their geographical distribution in Turkey

This review presents a search of the literature about gastrointestinal nematodosis of small ruminants. The search was performed on 58 articles published on necropsied sheep and goats between 1937 and 2011 in Turkey. This review identified 43 nematode species belonging to sheep and goats, assessed the prevalence of infection in different regions of Turkey, and evaluated the effect of age, sex, race, nutrition, and seasonal condition. This is the first review that specifically evaluated the gastrointestinal nematodes of small ruminants for 74 annual periods in Turkey.

Cysticercus bovis in slaughtered cattle in the Afyonkarahisar and Burdur provinces and its importance from the point of view of public health

OBJECTIVE This study was conducted to determine the current status of bovine cysticercosis and human taeniosis in two provinces (Afyonkarahisar and Burdur in the western part of Turkey between October 2009 and October 2011). METHODS In the study period, a total of 1684 cattle and 7644 human stool samples were examined for Cysticercus bovis, and Taeniosis, respectively. Carcasses of animals were subjected to routine meat inspection. Stool samples of humans were analysed macroscopically and microscopically including direct and formaldehyde-ether sedimentation methods. RESULTS C. bovis was determined in 0.24% of cattle by postmortem examination. The prevalence of infection was found to be 0.46% in Afyonkarahisar and 0.09% in Burdur. Taenia sp. eggs were shown in 0.1% of the human stool samples. The infection rate was detected as 0.1% and 0.09% in Afyonkarahisar and Burdur, respectively. CONCLUSION This study is characterized as a preliminary investigation which offers useful information on a public health level within a short time at a low cost. Results obtained from this study cannot be generalized to study areas in epidemiological terms, but they are useful data for the relevant geography.
