Cats are the most important hosts in the epidemiology of Toxoplasma gondii infections in humans and animals. Serologic and parasitological prevalence of T. gondii were determined in 237 cats from 15 counties in São Paulo state, Brazil. Antibodies to T. gondii were found in a 1:25 dilution of serum of 84 (35.4%) out of 237 cats by the modified agglutination test (MAT). Samples of brain, heart, t...

Background: Trichomoniasis has important medical, social and economical implications regarding its serious potentially associated complications, with the possibility of HIV acquisition and transmission. T. vaginalis is a very complex organism. Studying the variation in some biological and biochemical properties of the parasite can be used for characterization of the parasites. Objective: For th...

background: in spite of sufficient knowledge about phenotypic variation of trichomonas vaginalis , its genetic characteristics are poorly understood. we carried out a molecular epidemiology study in which in vitro metronidazole susceptibility of t. vaginalis isolates was considered. methods : this study was conducted on 862 women admitted to gynecology clinics in hamadan, west of iran, during 2...

Ambient nitrous oxide (N(2)O) emissions from Great Boiling Spring (GBS) in the US Great Basin depended on temperature, with the highest flux, 67.8 ± 2.6 μmol N(2)O-N m(-2) day(-1) , occurring in the large source pool at 82 °C. This rate of N(2)O production contrasted with negligible production from nearby soils and was similar to rates from soils and sediments impacted with agricultural fertili...
