objectives:prenatal infections are one of the fundamental causes of early puerperal complications in mothers and neonates. these infections are mostly due to colonized organisms in pregnant woman's genitor-urinary system. the aim of this study was to determine the incidence of streptococcus group b (gbs) colonization in parturient women and the rate of pathogen transmission to the newborn....

objective: this study presents a simple method for isolation, expansion and purification of neonatal mouse spermatogonial stem cells. methods: we used enzymatic digestion to isolate a cell suspension of spermatogonia and sertoli cells from neonatal 2-day-old mice. the cells were cultured in dmem/f12 that contained 10% serum for two weeks. sertoli and spermatogonia cell characteristics were conf...

Enterotoxigenic Escherichia coli (ETEC) is a leading cause of infectious diarrhea worldwide. Four categories of antigens have been commonly studied: O serogroup, H serogroup, colonization factor antigens (CFA), and toxins. A database has been complied from published reports of nearly 1,000 ETEC isolates from 18 locations and analyzed to determine the occurrence, distribution, and associations o...

Enterotoxigenic Escherichia coli (ETEC) is the most commonly isolated pathogen responsible for travelers' diarrhea and the cause of up to 650 million cases of pediatric diarrhea per year in the developing world. As a safe alternative to the prophylactic use of antibiotics, a hyperimmune bovine milk antibody product with specific activity against purified colonization factor antigens (CFAs) was ...

This prospective clinical study was performed to investigate the colonization of H pylori in adenoid and tonsil tissues by using the Campylobacter-like organism (CLO) test. Included in the study were 56 patients aged 3 to 43 yrs who had undergone adenoidectomy, tonsillectomy or adenotonsillectomy procedures under general anesthesia. Two-mm diameter tissue pieces of adenoid and tonsil specimens ...

background nasal colonization of healthy children with staphylococcus aureus is an important risk factor for different infections. detection of colonized individuals with methicillin resistant s. aureus (mrsa) and its eradication is the proper prevention strategy for infection spread in the community and health-care centers. objectives the aim of this study was to determine the prevalence, asso...

Background: Periprosthetic joint infection is a devastating complication of total joint arthroplasty. It seems that thepatient’s skin, nose, throat, and urine are important sites for microbial colonization. Colonization with staphylococcusaureus, especially methicillin resistant increases the risk of periprosthetic joint infection. The aim of this study was toassess the prevalence of staphyloco...
