Phage Typing, Biotyping & Antimicrobial Resistance Profile of Salmonella Enterica Serotype Typhi from Kolkata.

Background & objectives: Kolkata and its suburbs in eastern India are known to he endemic for typhoid fever. The objective of this study was to determine phage types, biotypes and antimicrobial resistance patterns of Salmonella enterica serotype Typhi isolated during the period 2003-2005 from a prospective surveillance for typhoid fever in two urban slums in […]

Analysis of Glycosidases Activity in Chlamydia Trachomatis L2 Serotype.

Analysis of Glycosidases Activity in Chlamydia Trachomatis L2 Serotype.

Abstract: Chlamydiae are prokaryotic, gram negative, intracellular parasites, causing a number of human diseases with serious sequelae. The exact mechanism of chlamydial attachment and entry into the host cell is still unclear. Chlamydia trachomatis, [SA.sub.2]F (L2) was tested for the activity of glycosidases. Glycosidases are involved in the synthesis and breakdown of cell-wall polysaccharides, and […]

Serotype Distribution of Streptococcus Pneumoniae Strains in the Nasopharynx of Healthy Turkish Children.

Serotype Distribution of Streptococcus Pneumoniae Strains in the Nasopharynx of Healthy Turkish Children.

Background & objectives: There is scanty information available on the pharyngeal carriage of Streptococcus pneumoniae and serotype distribution in healthy Turkish children. We therefore undertook this study to determine the serotype prevalence of pharyngeal S. pneumoniae Isolates of healthy school children in Turkey. Methods: Pharyngeal swabs were collected from 1440 healthy children (Ages 6-13) between […]
