outbreak of cryptosporidiosis in dairy goats in outbreak of cryptosporidiosis is reported among 22 suckling kids aged one to two weeks which were maintained for experimental purposes at the veterinary hospital of the university of minas gerais. they were divided into three groups. group a consisted of 10 animals with acute diarrhoea; initially their faeces were pasty but later they were excreted in watery streams. the animals were treated with gentamicin and fluid therapy but did not respond to treatment and died within a week. postmortem ...19979149363
diversity of virulence profiles of shiga toxin-producing escherichia coli serotypes in food-producing animals in brazil.the prevalence, serotypes and virulence profiles of shiga toxin-producing escherichia coli (stec) were investigated in 205 healthy beef and dairy cattle, and 106 goats reared in the southeastern region of minas gerais state, brazil. the prevalence of stec was 57.5% (61/106) in goats, 39.2%, (40/102) in beef cattle and 17.5% (18/103) in dairy cattle. among the 514 stec isolates, 40 different serotypes were found and some of them were identified in a specific host. stec isolates harboring stx1 cor ...200818678426
high seroprevalence of caseous lymphadenitis in brazilian goat herds revealed by corynebacterium pseudotuberculosis secreted proteins-based elisa.we conducted a seroepidemiological survey to determine the prevalence of caseous lymphadenitis (cla) in goat herds in minas gerais state, brazil. serum samples were collected from goats (n=676) from 108 rural properties in 2001, covering most of the sub-regions of this ca. 586,500 square kilometer state. antibodies against corynebacterium pseudotuberculosis secreted proteins were detected by an indirect enzyme-linked immunosorbent assay (elisa). most of the animals (78.9%) tested positive for cl ...201019665155
management practices to control gastrointestinal parasites in dairy and beef goats in minas gerais; brazil.parasitic infection is recognized worldwide as a limiting factor in the production of goats, and various control methods are used to reduce economic losses, often without considering the epidemiology of the parasites. this has led to the development of highly tolerant parasite populations and the presence of chemical residues in the beef and milk. the objective of this study was to determine the level of knowledge of goat farmers about parasitic diseases and to correlate this with the epidemiolo ...201021232868
molecular characterization of corynebacterium pseudotuberculosis isolates using eric-pcr.caseous lymphadenitis is an infectious sheep and goats disease caused by corynebacterium pseudotuberculosis and characterized by abscesses in superficial and visceral lymph nodes. c. pseudotuberculosis strains isolated from these hosts have been shown to be very difficult to type by the existing methods. the aim of this study is evaluating the potential of the enterobacterial repetitive intergenic consensus (eric-pcr) as a tool for molecular typing of c. pseudotuberculosis strains isolated in sh ...201121733644
high sero-prevalence of caseous lymphadenitis identified in slaughterhouse samples as a consequence of deficiencies in sheep farm management in the state of minas gerais, brazil.abstract:201122067701
seroprevalence and risk factors for leptospirosis in goats in uberlândia, minas gerais, brazil.the prevalence of leptospirosis in goat herds of the state of minas gerais has seldom been studied. the present research had as its objectives: (1) investigate the seroprevalence of leptospirosis in the county of uberlândia, mg, (2) verify the leptospirosis serovars, and (3) identify the risk factors associated with infection on the farms examined. serum samples from 230 animals in 11 properties were tested using the microscopic agglutination test. an epidemiological examination furnished data f ...201121647773
seroprevalence of toxoplasma gondii infection in goats by the indirect haemagglutination, immunofluorescence and immunoenzymatic tests in the region of uberlândia, brazil.a comparative study of the indirect haemagglutination (iha), immunofluorescence (ifat) and immunoenzymatic (elisa) tests was carried out to determine the prevalence of toxoplasma gondii antibodies in goats. one hundred seventy-four serum samples were obtained from four goat herds from the region of uberlândia, state of minas gerais. the distribution of the animals, according to their origin, was as follow: 71 from herd i; 39 from herd ii; 37 from herd iii; and 27 from herd iv. serum samples were ...200111500772
eimeria minasensis n. sp. (apicomplexa: eimeriidae) in the domestic goat capra hircus, from brazil.eimeria minasensis n. sp. is described in the domestic goat capra hircus from brazil. oocysts ellipsoidal are 35 x 24.5 (32-37.7 x 20.9-27.9) microns. sporocysts elongate-ellipsoid are 15.2 x 9 (12.3-18.4 x 7.8-10.2) microns, with a stieda body at the narrow end. oocyst wall smooth and bilayered; outer layer about 1.2 (0.8-1.6) microns and colorless; inner layer about 0.5 (0.4-0.8) micron and dark-brown. micropyle, a mound-shaped micropylar cap 1.6 x 8.9 (0.8-2 x 7-10.2) easily dislodged; one or ...19989921296
ecotopes, natural infection and trophic resources of triatoma brasiliensis (hemiptera, reduviidae, triatominae).triatoma brasiliensis is considered as one of the most important chagas disease vectors in the northeastern brazil. this species presents chromatic variations which led to descriptions of subspecies, synonymized by lent and wygodzinsky (1979). in order to broaden bionomic knowledge of these distinct colour patterns of t. brasiliensis, captures were performed at different sites, where the chromatic patterns were described: caicó, rio grande do norte (t. brasiliensis brasiliensis neiva, 1911), it ...19989698835
seroprevalence and risk factors of caprine toxoplasmosis in minas gerais, brazil.the objective of this work was to carry out a study on caprine toxoplasmosis in the state of minas gerais, brazil. to determine the prevalence of toxoplasmosis in goats in minas gerais, 767 sera from goats were tested by elisa (enzyme-linked immunosorbent assay) and ifat (indirect fluorescence antibody test). the prevalence of antibodies to toxoplasma gondii was 43.0% and 46.0% by elisa and ifat, respectively. it was observed that 26.8% of the goats show low-avidity igg to t. gondii. these resul ...200919091475
