Staphylococcus aureus is responsible for a wide range of infections, including soft tissue infections and potentially fatal bacteremias. The primary niche for S. aureus in humans is the nares, and nasal carriage is a documented risk factor for staphylococcal infection. Previous studies with rodent models of nasal colonization have implicated capsule and teichoic acid as staphylococcal surface f...
background and objectives: recently, nosocomial infections have been discussed as a critical issue among intubated patients leading to significant morbidity and mortality. hence, the pattern of microbiological colonization and antibiotic resistance are much valuable in this regard. we aimed to investigate the pattern of microorganism colonization and antibiotic resistance in patients with endot...
study the effects of inoculation with two arbuscular mycorrhizal (am) fungi, gm (glomus mosseae t.h. nicolson & gerd.)gerd & trappe) and gi (glomus intraradices n.c. schenck & g.s. sm.) on the herb yield, essential oil (eo) content and nutrient acquisition of basil (ocimum basilicum l.) under drought stress conditions,the experiment conducted with 9 treatments and 4 replications. drought stre...
Two-component signal transduction systems (TCS) are used by bacteria to sense and respond to their environment. TCS are typically composed of a sensor histidine kinase (HK) and a response regulator (RR). The Vibrio cholerae genome encodes 52 RR, but the role of these RRs in V. cholerae pathogenesis is largely unknown. To identify RRs that control V. cholerae colonization, in-frame deletions of ...
The genome sequence of the human pathogen Campylobacter jejuni NCTC11168 has been determined recently, but studies on colonization and persistence in chickens have been limited due to reports that this strain is a poor colonizer. Experimental colonization and persistence studies were carried out with C. jejuni NCTC11168 by using 2-week-old Light Sussex chickens possessing an acquired natural gu...
The mechanism of antibody-mediated reduction of Haemophilus influenzae type b (Hib) carriage was studied in the infant rat colonization model. Monoclonal Hib polysaccharide (PS) antibody (MAb) given intranasally or intraperitoneally and human secretory anti-Hib PS IgA given intranasally inhibited colonization by Hib during the entire follow-up period (2-48 h after challenge) but did not affect ...
A greenhouse experiment was conducted to study the effect of zinc rates, arbuscular mycorrhiza and organic matter, on corn growth and micronutrients-uptake in a calcareous soil. Experimental design was factorial based on complete randomized design with 3 replications. Treatments consisted of 3 levels of Zn (0, 5 and 10 mg Zn/kg), 2 types of organic manure (sheep manure and municipal waste compo...
Background : Denture stomatitis is a common inflammatory complication of the candidiasis seen under the maxillary denture, which is observed in 70% of cases following a chronic trauma. Candidia species particularly Candida albicans are known as one of endogenous etiologic agent of denture stomatitis that may cause systemic opportunistic infection in immunosupressed subjects. The aim of presen...
Nowadays, group B streptococcus (GBS) is considered an important agent in early-onset infection in newborn infants. This is often transmitted to the child from the birth canal. Neonatal infection depends on degree of colonization of mother's vagina in labor. This study was conducted at two obstetrical teaching hospitals in Tehran (Shahid Akbarabadi and Mirza Kuchak Khan). Specimens were obtaine...
Abstract Background and purpose: The yeast fungi including Candida and Malassezia genus are normal flora of the skin of human and male genital region. They could cause balanitis and urinary tract infections. The aim of this study was to determine the prevalence of yeast colonization on preputial area of infant prior to circumcision. Materials and methods: A total of 200 (<one year of age) c...
