Background: It is not yet known which types of Toll-like receptors (TLRs) are most effective in Helicobacter pylori (H. pylori) recognition. It is also not known which gastric zones have the most prominent roles in TLR-mediated bacterial recognition. The aim of this work was to analyze the expression of TLR2 and TLR4 in biopsy specimens from H. pylori-infected patients. Methods: Thirty-eight...

EXTRAHEPATIC MANIFESTATIONS IN CHRONIC HEPATITIS B – THE EXPERIENCE OF THE IASI INFECTIOUS DISEASES HOSPITAL BETWEEN 2012-2014 (Abstract): There are numerous extrahepatic syndromes associated with HBV infection: vascular, renal, and cutaneous manifestations, essential mixed cryoglobulinemia, and neurological phenomena. Aim: This study proposes an approach to the extrahepatic manifestations of c...

Objective Little attention has been given to acute hematogenous osteomyelitis (AHO) caused by group A -hemolytic Streptococcus (GABHS), although up to 10% of cases are caused by this microorganism. The objective of this study was to define the clinical and laboratory characteristics of AHO caused by GABHS. Methods. Between January 1983 and June 1999, 29 patients were treated at Children’s Natio...

First six cases of neonatal group B B haemolytic streptococcal sepsis in GHKL & Maternity Hospital K.L. were reported and in one third, it was fatal. Five of the cases were 'early onset' type and one was 'late onset' type. While maternal infant transmission of the disease is important in the 'early onset' type, environmental sources of infection are also significant. No gestational age or birth...

Lipids extracted from rabbit skin block the hemolytic capacity of SO and also suppress the neutralizing antibody response to this streptococcal extracellular antigen in rabbith immunized intravenosly. The modification in antibody response is specific for SO; the antibody responses to streptococcal DNase B and to streptococcal NADase are not affected. Cholesterol, a lipid present in abundance in...

The CAMP (Christie-Atkins-Munch-Petersen) test is commonly used for the presumptive identification of Streptococcus agalactiae (Lancefield group B). Using 350 clinical isolates of beta-hemolytic streptococci, we compared a 30-min spot CAMP test with the standard overnight CAMP test and the Lancefield precipitin test. We found 99% agreement among all three tests for all streptococci tested. The ...

We studied the factors influencing the colonization of Streptococcus in school age children aged 6-11 years from 2 low socioeconomic schools of the Bangkok Metropolitan area. 4,055 throat swab cultures were performed. Beta hemolytic Streptococcus (BHS) and beta hemolytic Streptococcus group A (BHSA) were isolated in 1,747 (43%) and 744 (18%) respectively. 1,547 questionnaires were returned from...
