The prevalence of colonization with the anaerobic intestinal spirochaetes Brachyspira aalborgi and Brachyspira pilosicoli was investigated in humans (n = 316) and dogs (n = 101) living on three tea estates in Assam, India. Colonization was detected using PCR on DNA from faeces. Nineteen (6%) human faecal samples contained B. aalborgi DNA, 80 (25.3%) contained B. pilosicoli DNA, and 10 (3.2%) co...

To assess the prevalence and risk factors for colonization with Staphylococcus aureus in inmates entering two maximum-security prisons in New York State, USA, inmates (N=830) were interviewed and anterior nares and oropharyngeal samples collected. Isolates were characterized using spa typing. Overall, 50·5% of women and 58·3% of men were colonized with S. aureus and 10·6% of women and 5·9% of m...

Actinobacillus pleuropneumoniae is the causative agent of porcine pleuropneumonia. The virulence factors of this microorganism involved in colonization and the induction of lung lesions have been thoroughly studied and some have been well characterized. A. pleuropneumoniae binds preferentially to cells of the lower respiratory tract in a process involving different adhesins and probably biofilm...

BACKGROUND AND PURPOSE To evaluate the impact of 23-valent polysaccharide pneumococcal vaccine on Streptococcus pneumoniae colonization in the upper airway of patients with human immunodeficiency virus (HIV)-1 in Taiwan. METHODS 302 HIV-infected patients aged 15 years or older underwent swab cultures of the posterior pharynx and tonsils for S. pneumoniae between June 1, 2000 and June 30, 2002...

BACKGROUND Patients with severe chronic obstructive pulmonary disease (COPD) are at increased risk of infection by P. aeruginosa. The specific role of bronchiectasis in both infection and chronic colonization by this microorganism in COPD, however, remains ill defined.To evaluate the prevalence and risk factors for P. aeruginosa recovery from sputum in outpatients with severe COPD, characterizi...

UNLABELLED The colonization of the oral cavity is a prerequisite to the development of oropharyngeal candidiasis. AIMS The aims of this study were: to evaluate colonization and quantify Candida spp. in the oral cavity; to determine the predisposing factors for colonization; and to correlate the levels of CD4+ cells and viral load with the yeast count of colony forming units per milliliter (CF...

Campylobacter contaminated broiler chicken meat is an important source of foodborne gastroenteritis and poses a serious health burden in industrialized countries. Broiler chickens are commonly regarded as a natural host for this zoonotic pathogen and infected birds carry a very high C. jejuni load in their gastrointestinal tract, especially the ceca. This eventually results in contaminated carc...

Background. Infections due to fluoroquinolone-resistant Escherichia coli (FQREC) are preceded by gastrointestinal colonization, and are associated with significant morbidity and mortality. Although colonization with FQREC is common among residents of long-term care facilities (LTCFs), risk factors associated with subsequent development of clinical infections in this population remain unclear. T...

  NEC (Necrotizing Enterocolitis) is an increasing clinical burden to patients, families, and the neonatology health care team. Although the diagnosis is straightforward, the morbidity and mortality associated with the disease are not improving. Risk factors of prematurity, formula feeding, intestinal ischemia/hypoxia, and bacterial colonization accentuate the imbalance toward mucosal stress wi...

Enterotoxigenic Escherichia coli (ETEC) strains harbor multiple fimbriae and pili to mediate host colonization, including the type IVb pilus, colonization factor antigen III (CFA/III). Not all colonization factors are well characterized or known in toxin positive ETEC isolates, which may have an impact identifying ETEC isolates based on molecular screening of these biomarkers. We describe a nov...
