isolation and genetic characterisation of toxoplasma gondii from a red-handed howler monkey (alouatta belzebul), a jaguarundi (puma yagouaroundi), and a black-eared opossum (didelphis aurita) from brazil.toxoplasma gondii isolates are highly diverse in domestic animals from brazil. however, little is known about the genetics of this parasite from wild mammals in the same region. reveal genetic similarity or difference of t. gondii among different animal populations is necessary for us to understand transmission of this parasite. here we reported isolation and genetic characterisation of three t. gondii isolates from wild animals in brazil. the parasite was isolated by bioassay in mice from tissu ...201021055880
[species of the genus eimeria schneider, 1875 (apicomplexa: eimeriidae) in dairy goats maintained in intensive system in the são josé do rio preto region, são paulo state, brazil].were examined 58 dairy goats, 41 kids and 17 adults, saanen and alpine breeds, males and females, in intensive system, in the são josé do rio preto region, são paulo state, for detection and identification of eimeria spp. oocysts. the 58 feces samples analyzed by the centrifugal-flotation technique, were positive for, at least, one eimeria species. the eimeria species found in this research were: e. ninakohlyakimovae (77,6%), e. jolchijevi (72,4%), e. alijevi (63,8%), e. christenseni (63,8%), e. ...200516153337
[cooperia curticei giles, 1892 (nematoda: trichostrongylidae) parasite of goats (capra hircus) in the state of são paulo, brazil (author's transl)].cooperia curticei giles, 1892 (nematoda: trichostrongylidae) is reported, for the first time, parasitizing the small intestine of goats (capra hircus) in the state of são paulo, brazil. the animals came from the region of the alta araraquarense. the spicules of the worms were well chitinized and measured, on the average, 153,68 micrometer with a standard error of 0,91 micrometer.1977607911
evaluation of a gmp training of milkers in dairy goat farms in são paulo, brazil.a good manufacturing practices (gmp) training course was applied for goat milkers and evaluated using microbiological analysis in milk before and after training. milkers from three dairy goat farms located in são paulo, brazil, were submitted to a one-hour course on gmp and recommended guidelines for milking. samples of raw milk were collected before and one to two months after training, and analysed for aerobic mesophilic, psychrotrophic, coliform, staphylococcus aureus and salmonella spp count ...200616507483
genetic diversity among toxoplasma gondii isolates of small ruminants from brazil: novel genotypes revealed.recent studies indicated that toxoplasma gondii isolates of many domestic animal hosts from brazil are genetically and biologically different from those in usa and europe. despite of high pathogenicity of this parasite to small ruminants, the epidemiology and genetic diversity of t. gondii in these animals are not well understood in brazil. in this study, a total of 28 t. gondii samples (16 isolates from sheep in são paulo state, and 12 isolates from goats in the states of são paulo and rio gran ...201020236768
[seroprevalence of toxoplasma gondii in dairy goats in the são paulo state, brazil].four hundred forty-two serum samples were collected from dairy goats in seven regions of são paulo state. these were tested for toxoplasma gondii antibodies using the indirect immunofluorescent antibody test. sixty-four (14.5%) serologically positive animals were found from all these goat farms studied.200315049121
