introduction : staphylococcus aureus colonization has been recognized as one of the most important risk factors for subsequent infections with this microorganism. in this study, we intended to identify all patients who were mrsa-positive upon admission and compare the prevalence of mrsa colonization on different days of study admitted in imam reza hospital in mashhad, iran. methods : this cross...

objective: this study presents an efficient, cost-effective method to improve proliferation and colonization of spermatogonial stem cells (sscs) in vitro. methods: isolated sscs from neonate mice were cultured in dmem culture medium with 10% fetal bovine serum (fbs). in the first phase of the study, the temperature was controlled by low intensity pulsed ultrasound stimulation (lipus) of the pla...

conclusions the results of the present study demonstrate that oral contraceptives containing estradiol can lead to candida colonization in the oral cavity. it is recommended that further studies comparing the influence of oral contraceptives on candida’s adherence to the epithelium is highly recommended. results the frequency of positive cultures of candida albicans was higher (p value = 0.03) ...

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 ...
