chlamydia trachomatis is an obligate intracellular bacterium which causes a wide variety of human infections such as ocular, urogenital and respiratory infections. genital infections of women, espe-cially when repeated, give rise to many complications such as ectopic pregnancy, miscarriage and in fertility. since chlamydial infections are usually asymptomatic, they progress unnoticed and produc...

background: antifertility effect of naturally occuring antisperm antibody (asa) in infertile couples and studies on experimental immunization of various animals with sperm antigens represents asa as immunocontraceptive target. despite extensive research on the effects of different factors on sperm immunogenecity and asa production variable result have been reported. objective: to study whole sp...

background: the major cause of peptic ulcer disease is helicobacter pylori (hp), and it is also implicated in the pathogenesis of adenocarcinoma of the distal stomach and gastric lymphoma. the incidence of peptic ulcer disease, atrophic gastritis, and gastric adenocarcinoma are more common in people infected of caga positive strains of hp. the aim of this study was to determine the prevalence o...

neuromyelitis optica (nmo) is an autoimmune inflammatory disease of the central nervous system with preferential involvement in the optic nerve and spinal cord with a widespread spectrum of clinical features; multiple therapeutic agents have been used with different results. recent evidence points to b?cell?mediated humoral immunity in the pathogenesis of nmo. rituximab targets the cd20 antigen...

newcastle disease virus (ndv) is known as one of the most important endemic viral pathogen for various avian species such as ostrich, in iran. therefore, establishing a routine vaccination program against nd in ostrich flocks would be useful in order to reduce the danger of this infection. newcastle disease occurs among the ostriches and leads to high rate of mortality while most of the losses ...

the enterotoxins (ets) of clostridium perfringens isolated from enterotoxemic or diarrheic alpacas, pigs, calves, dogs, and horses were obtained from sporulated cell extracts. the ets from alpaca, pig, and calf isolates were chromatographed on sephadex g-loo. monoclonal antibodies (mabs) against ets derived from alpaca, pig, and calf c. perfringens isolates were produced. the mabs were used in ...

conclusions basidomes collected from four locations in thailand had low genetic variation and their extracts inhibited the growth of all tested bacteria. the health benefits of this edible species should be evaluated further. background boletus griseipurpureus corner, an edible mushroom, is a putative ectomycorrhizal fungus. currently, the taxonomic boundary of this mushroom is unclear and its ...

background: streptokinase, which is injected intravenously with a standard dose of 1.5 miu, is the most widely used thrombolytic agent around the world. what is so important about this bioproduct is the level of antistreptokinase (anti-sk) antibody in the population, which is directly correlated to the incidence of streptococcal infections in that population. objective: since iran is an endemic...
