In order to determine the frequency of anti-Toxoplasma gondii IgG antibodies in domestic cats and to identify the possible risk factors, 169 domestic cats from 16 municipalities of Mexico City were studied. Their serum was tested by indirect ELISA and the owners answered a questionnaire about age, gender, litter box hygiene, contact with other cats, housing(More)
The objective of the present study was to determine the prevalence of parasitoses in stray dogs from Mexico City, as well as to describe the structure of the intestinal helminth communities present in said hosts. One hundred and twenty dog intestines were collected and dissected to evaluate their parasitic load; finding parasites in 102 dogs (85%). The(More)
Mannheimia spp. strains obtained from bovine nasal exudates of either clinically healthy or clinically affected by respiratory tract disease animals were isolated and characterised to estimate the prevalence of isolated serotypes in dairy farms in Mexico, by means of a trans-sectional descriptive study. Strains were isolated and typified through biochemical(More)
No epidemiologic study for cystic echinococcosis in México has yet been described. The objective of this work was to determine the prevalence and distribution of human echinococcosis in a community of the state of México and its probable risk factors. A cross-sectional study was performed; household census was used to randomly select houses. The larval(More)
INTRODUCTION Estrogens are well recognized as important hormones in male reproduction and act as ligands to alpha and beta estrogen receptors. Both estrogen receptors could interact with estrogen-mimicking compounds such as the fluorescent phytoestrogen coumestrol, which acts both in an agonist or antagonist fashion. OBJECTIVE To investigate the presence(More)
We evaluated the genetic variation of Echinococcus G7 strain in larval and adult stages using a fragment of the mitochondrial cox1 gen. Viscera of pigs, bovines, and sheep and fecal samples of dogs were inspected for cystic and canine echinococcosis, respectively; only pigs had hydatid cysts. Bayesian inferences grouped the sequences in an E. canadensis G7(More)
OBJETIVE The impact of a control program is evaluated to eventually eradicate taeniasis-cysticercosis (Taenia solium) based on education and vaccination of pigs. MATERIALS AND METHODS The prevalence of porcine cysticercosis was estimated using tongue inspection, ultrasound and determination of antibodies, before and three years after the application in(More)
OBJECTIVE To assess the frequency of Taenia solium carriers and its relationship with human cysticercosis in a Mexican locality. MATERIAL AND METHODS A cross-sectional study was conducted in 1998, in a locality of Guerrero State, Mexico. Four hundred and three fecal samples were analyzed by enzyme-linked immunosorbent assay (ELISA) to detect Taenia sp(More)
OBJECTIVE To assess the effect of different cooking times and temperatures, as well as of some seasonings, on the viability of Taenia solium metacestodes in spicy meat and hot sausage. MATERIAL AND METHODS This study was conducted by the Universidad Autónoma de Guerrero (Guerrero State Autonomous University), Mexico in 1999. Infected pork meat was bought(More)
