BACKGROUND The study of sperm-mycoplasma interaction has been focused on the effects of infection on sperm quality, but few studies have reported the direct interaction of this bacterium with spermatozoa. METHODS Selected populations of viable, motile and infection-free human spermatozoa from three healthy men were incubated with 15-480 multiplicity of(More)
Though the armadillo is important as a research model in leprosy studies, the activity of armadillo's neutrophils is an aspect of little research. The aim of this study was carried out to partially characterize the chemotaxis, endocytosis and bacteriocidal ability of the neutrophils found in the nine-banded armadillo (Dasypus novemcinctus). Results showed(More)
BACKGROUND Swine infectious pathogens, especially viruses, represent a potential public health risk associated with the use of pig tissues for xenotransplantation in humans. We hypothesized that porcine circovirus type I (PCV-1) may infect human mononuclear cells, resulting in ultrastructural alterations of the target cells. METHODS Transmission electron(More)
OBJECTIVE To determinate the frequency of Chlamydia trachomatis infection in male partners of infertile couples who attend to the infertility clinic at Instituto Nacional de Perinatología, as well as to compare the clinical data and lifestyle between C. trachomatis-infected and uninfected men to establish a possible association with gynecological damage in(More)
