Group B Streptococcus (GBS) is the leading cause of neonatal infections. Our purpose was to characterize GBS colonization in pregnant women, current serotypes, resistance phenotypes and genes associated with virulence. In Misiones, Argentina, there are no previous data on this topic. Vaginal-rectal swabs from 3125 pregnant women were studied between 2004 and 2010. GBS strains were identified by...
In a survey of five villages in the Eastern Highlands of Papua New Guinea, Serpulina pilosicoli was isolated from rectal swabs from 113 of 496 individuals (22.8%). Colonization rates ranged from 22.6-30.1% in four of the villages but was only 8.6% in the other village. In comparison colonization was demonstrated in only 5 of 54 indigenous people (9.3%) and none of 76 non-indigenous people livin...
Intestinal Colonization by Extended-Spectrum Beta-Lactamase-Producing Enterobacteriaceae in Infants.
BACKGROUND Members of the Enterobacteriaceae family are common agents of nosocomial infections. Intestinal colonization by these microorganisms represents a major step in the development of systemic infection. Extended-spectrum b-lactamase-producing bacteria are usually associated with outbreaks, but endemic infections are common in intensive care units. OBJECTIVE To determine the frequency o...
Type IV pili (TFP) are important colonization factors of the opportunistic pathogen Pseudomonas aeruginosa, involved in biofilm formation and attachment to host cells. This study undertook a comprehensive analysis of TFP alleles in more than 290 environmental, clinical, rectal and cystic fibrosis (CF) isolates of P. aeruginosa. Based on the results, a new system of nomenclature is proposed, in ...
BACKGROUND Systemic antibiotics vary widely in in vitro activity against Clostridium difficile. Some agents with activity against C. difficile (e.g., piperacillin/tazobactam) inhibit establishment of colonization in mice. We tested the hypothesis that piperacillin/tazobactam and other agents with activity against C. difficile achieve sufficient concentrations in the intestinal tract to inhibit ...
conclusion determination of colonized bacteria in oropharynx of healthy children and relationship between them can be helpful to find the ways to interfere with their colonization and prevention of diseases due to them. materials and methods the colonized bacteria in oropharynx of 296 children between 2-6 years old from 7 day care centers of tehran were isolated and determined by specific diagn...
OBJECTIVE Colonized and infected inpatients are major reservoirs for methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE), and transient carriage of these pathogens on the hands of healthcare workers remains the most common mechanism of patient-to-patient transmission. We hypothesized that use of alcohol-based, waterless hand antiseptic would lower the i...
the aim of this study was to evaluate the morbidity and mortality in patients with operable stage ii and iii rectal cancers within one or two months after surgery, who has been treated pre-operatively with short course radiotherapy. twenty-eight patients with rectal adenocarcinoma, consecutively referred to the cancer institute of imam khomeini hospital from march 2009 to march 2010, were selec...
bowel stent insertion has a variety of complications one major of which is colonic perforation. the purpose of this article is to reveal two cases with delayed colonic perforation after stent placement to relieve bowel obstruction caused by rectal cancer. the first patient was a 55 year-old man who was a candidate for stent placement to avoid palliative surgery and relieve his bowel obstruction...
