Visceral and cutaneous larva migrans are parasitic zoonoses caused by the infection of larval nematodes Toxocara sp. Ancylostoma respectively. The objective this study was to investigate contamination eggs soil samples collected from public parks children's playground areas in state Minas Gerais, Brazil, using both Baermann's method centrifugal flotation technique. were observed squares 17.4% (4/23) 69.6 (16/23) In schools child day care settings sand 11.1% (2/18).

Eleven identified, namely: E. bovis (23.2%), zuernii (22.6%), ellipsoidalis (20.3%), cylindrica (14.1%),...
Abstract The present study used the indirect fluorescent antibody test (IFAT) to determine seroprevalence of Sarcocystis neurona, Toxoplasma gondii and Neospora spp., evaluated variables associated with these infections among 506 apparently healthy horses, reared in south state Minas Gerais, Brazil. This was conducted between April 2012 October 2013. Among true prevalence S. neurona 26% (95% CI: 22.0-30.4%), T. 19.9% 15.5-24.8%) spp. 23.9% 19.9-28.1%); farms, 88.3% 74.4-91.6%), 71.6%...
O objetivo deste estudo foi determinar a freqüência de anticorpos anti-Neospora caninum em vacas e fetos provenientes municípios do sul Minas Gerais. Foram utilizadas 559 amostras soros um banco formado partir coletadas 18 propriedades produtoras leite, distribuídas por sete da microrregião Lavras, MG; 575 503 fetais, ambas no matadouro Campo Belo, MG. As foram submetidas à reação imunofluorescência indireta (RIFI-IgG), para pesquisa anti-N. caninum, considerando como ponto corte o título...
Neosporosis is an important cause of abortion in cattle and information on their genetics host parasite relationships are desirable. Neospora caninum samples obtained from 24 bovine fetuses Minas Gerais, were genetically analyzed part the rDNA region, coding for rRNAs. Previously, brain, heart, liver, skeletal muscle, lung, kidney, spleen, thymus, lymph nodes, ovary or testis, uterus skin ear by conventional histopathology immunohistochemistry. Of these, eight had lesions compatible brain...
Semi-systematized interviews were conducted with 100 dairy cattle producers in the municipality of Divinópolis, Minas Gerais, aim ascertaining their perceptions regarding importance Rhipicephalus (Boophilus) microplus and combating it. Content analysis was performed frequency distribution each variables used to construct profiles interviewed. The production losses caused by ticks perceived incompletely producers, who unaware pathogen transmission parasite indirect through it, such as cost...
The aim of this study was to determine the prevalence and risk factors associated with infection due Neospora caninum in serum samples from 488 sheep originating 63 farms municipalities distributed across eight twelve mesoregions state Minas Gerais, southeastern Brazil. For detection N. were subjected indirect fluorescence antibody test (IFAT ≥ 50). To identify a questionnaire filled out for each herd by interviewing, individual responsible herd, demanding information on general...

A Encephalitozoon-like microsporidia was found in epithelial cells of the midgut and salivary glands Amblyomma cajennense (F.) Anocentor nitens (Neumann) that had fed on rabbits. Ultrastructural studies demonstrated all stages life cycle parasite occur parasitophorous vacuoles contain only 1 nucleus. The sporonts detach from limiting membrane vacuole divide by binary fission to produce sporoblasts, each presenting a thickened electron-dense wall, primordium polar filament. Each spore...
