BACKGROUND: Toxoplasma gondii is an obligate intracellular protozoon with worldwide distribution that infects human and a wide spectrum of warm- blooded animals. OBJECTIVES: The aim of the study is to survey the prevalence of T.gondii antibody in slaughtered livestock in slaughterhouse with modified agglutination test in Sanandaj in 2015. Methods: Totally 343 serum samples were collected from 130 cows, 111 sheep and 102 goats from May to July 2015 in Sanandaj slaughterhouse. Sera were examined with modified agglutination test (MAT) for T.gondii antibody and 1.40 titer antibody and above was considered as positive. Results: Antibodies of T.gondii were found in sera of 51 out of 343 (15.45%) samples. From 51 seropositive sera, 13 cows (23.84), 13 goats (12.74%) and 9 sheep (8.1%) were infected. The differences among species were statistically significant (P≥.002). Conclusions: Results indicate that T. gondii in sheep, goats and especially cows is prevalent, so consumption of undercooked meats should be avoided, also the prevention methods of infection should be taught to the people and due to the possibility of limitations in the results of serological tests, repetition of the study using molecular techniques is recommended

Study on DNase activity specific from Haemonchus contortus reproductive tissue
Kwak, D.M.(Washington State University, Pullman, WA, USA)E-mail:dmkwak@vetmed.wsu.edu
DNase activity in Haemonchus contortus reproductive tissue was characterized and compared to that in whole worm. DNase activity in reproductive tissue was detected throughout pHs 4-10 with high activity under acidic conditions. The activity was not inhibited by 10 mM EDTA at pH 5.0, but largely inhibited by pH 7.0. The activity produced DNA fragments with mixtures of 3'-hydroxyls (OH) and 3'-phosphates (P) at each pH. Three distinct DNase activities were identified and had M∧rs of 34, 36 and 38.5 kDa in zymograms, which were distinguished according to pH requirement and sensitivity to EDTA.

A cross-sectional study was conducted from November 2011 to April 2012 on a total of 384 pigs from two privately owned intensive farms in Bishoftu, Ethiopia. The objectives of the study were to identify and determine the prevalence of common parasites of pigs. For the determination of gastrointestinal (GIT) parasites, faecal samples were collected from the study animals and subjected to standard parasitological examination techniques. Physical examination was conducted for the presence of skin parasitic lesions and skin scrapings were collected to determine prevalence of ectoparasites. The overall prevalence of GIT parasites in the pigs was 25% (96/384). Examination of faecal samples revealed the ova or oocysts of four different gastrointestinal parasites, namely Coccidia (12%), Strongyles (5.2%), Ascaris suum (4.9%) and Trichuris suis (2.9%). Mixed infection by at least two parasite species was observed in 3.65% (14/384) of the pigs. The only ectoparasite species identified was Sarcoptes scabiei var. suis, with a prevalence of 2.6%. This study indicates that pig parasites are a major problem in the study area, hence implementation of strategic control measures and appropriate hygienic management systems are recommended to reduce the prevalence of parasites.
Mostrar más [+] Menos [-]Comparison of DNase activities from excretory/secretory products of Haemonchus contortus fenbendazole-resistant
Kwak, D.M.(Washington State University, Pullman, WA, USA)E-mail:dmkwak@vetmed.wsu.edu
Change in β-tubulin nucleic acid and protein sequences was the only known difference between Haemonchus contortus fenbendazole (FBZ)-resistant and -susceptible isolates. This change was sufficient to determine the pathologic effect induced by FBZ treatment. This research was initiated to investigate further differences from these two isolates. Since β-tubulin is involved in formation of microtubule, which has functions in secretory vesicle transport, DNase activities from excretory/secretory products (ESP) of the two isolates were compared, based on pH, sensitivity to DNase inhibitors, molecular masses and production of 3'-OH.

Assessment of Parasitic Contamination in the Washings of Routinely Used Vegetables in Puducherry City.

Das, S.S. | Kumar, D. | Sreekrishnan, R.
Out of73 washing samples from commonly used vegetable viz. dhania (14), coriander (Coriandrum sativum) (12), pudina (11), spinach (Spinacia oleracea) (9), carrot (15) and raddish (12) collected either from local vegetable markets or residences, only 2 carrot washings and one radish washing were found positive for strongyle ova and one dhania sample was positive for ascarid ova.

Objectives: The objective of this work was to estimate the diversity of gastrointestinal (GI) para¬site species, their prevalence, and risk factors in Black Bengal goats (BBGs) of Natore, Bangladesh. Materials and Methods: Fecal samples from randomly selected 260 BBGs were processed through Stoll's ova counting method, floatation, and simple sedimentation method. Microscopy-based identification of parasitic eggs, cysts, or oocysts was made. A semi-structured question¬naire-based data on host and management practices were collected from the owner. Data analysis was done using Statistical Package for Social Sciences. Results: The overall prevalence of GI parasites in BBGs was 65.4%, with an individual prevalence of 8.5% for Fasciola gigantica, 21.5% for Paramphistomum spp., 20% for Haemonchus spp., 34.2% for Strongyloides spp., 8.5% for Trichuris spp., and 9.2% for Eimeria spp. No significant effect of host age, gender, body condition, animal rearing system, or housing floor type was observed on parasitism. Animals of young age, female, poorly body-conditioned, living in a free-range system, and housed on a muddy floor had a relatively higher susceptibility to infection. Deworming had a significant impact on reducing the frequency of caprine GI parasitism. Conclusions: Despite the significant effect of anthelmintic, the elevated prevalence of GI parasites in BBGs suggests a critical need for developing effective strategies to prevent caprine parasitoses.
