OBJECTIVE To determine the vaginal-rectal colonization rate with group A streptococci in late pregnancy. METHODS All patients delivering at a northern New England hospital over a 38 month period had 35-37 week vaginal-rectal swabs cultured for group A and group B streptococci, using selective media and slide agglutination. RESULTS Six thousand nine hundred forty-four screening cultures were...
INTRODUCTION During the last few decades, group B Streptococcus (GBS) has emerged as an important pathogen. The major reservoirs for GBS are the vagina and the peri-anal regions/rectum, and the colonization of these regions is a risk factor for subsequent infection in pregnant women and newborns. METHODOLOGY A prospective study was performed to determine the prevalence of GBS colonization in ...
BACKGROUND There is evidence that Candida colonization contributes to increasing invasion of candidiasis in hospitalized neonates. Few studies investigated the epidemiology and risk factors of Candida colonization among hospitalized and non-hospitalized infants. This prospective study investigated the major epidemiological characteristics of Candida species colonizing oral and rectal sites of J...
Escherichia coli O157:H7 is an important pathogen of humans. Cattle are most frequently identified as the primary source of infection, and therefore, reduction in E. coli O157:H7 prevalence in cattle by vaccination represents an attractive strategy for reducing the incidence of human disease. H7 flagella have been implicated in intestinal-epithelial colonization of E. coli O157:H7 and may repre...
BACKGROUND & OBJECTIVES There is paucity of information on vaginal and rectal colonization with multiple serotypes of group B streptococci (GBS). As part of an ongoing cohort study evaluating the natural history of vaginal and rectal colonization by GBS, the colonization with multiple serotypes was studied in 102 non-pregnant women aged 18-30 yr. METHODS Up to ten separate colony picks of bet...
Enterohaemorrhagic Escherichia coli O157 : H7 is a bacterial pathogen that can cause haemorrhagic colitis and haemolytic uremic syndrome. In the primary reservoir host, cattle, the terminal rectum is the principal site of E. coli O157 colonization. In this study, bovine terminal rectal primary epithelial cells were used to examine the role of H7 flagella in epithelial adherence. Binding of a fl...
In a survey of gastrointestinal staphylococcal colonization conducted in hospitalized burned patients, rectal swab cultures yielded Staphylococcus aureus significantly more often (34/65, 52%) than simultaneously collected stool cultures (24/65, 37%; P less than 0.01).
During an outbreak of methicillin-resistant Staphylococcus aureus (MRSA) in the neonatal intensive care units at two hospitals, we assessed several sites for detection of MRSA colonization. Nasal cultures found 32 of 33 MRSA-colonized patients (97%). Rectal cultures detected 29% of 24 MRSA-colonized patients identified by paired rectal and nasal samples and axillary samples found 22% of 9 MRSA-...
Introduction Emergence of carbapemenases and their worldwide distribution has worsens the clinical scenario of antibiotic resistance in Gram-negative bacteria. Selective Digestive Decontamination (SDD) has been used to prevent development of nosocomial colonization and infections in ICU patients. However, rectal colonization with multirresistant bacteria is a serious concern with SDD. An effect...
