Group B Streptococcal Sepsis in a Newborn: a Case Report
Newborns’ bacterial infections due to group B Streptococcus (GBS) happen in two forms including early-onset disease or late-onset disease. In this paper, we report a case of early-onset GBS infection in a male infant. A 22-year-old primigravid woman delivers a term normal looking male infant. Nasal flaring, grunting, and poor feeding presented soon after birth. An empiric treatment wit...
متن کاملImmunological and chemical studies of the streptococcal group O protein type antigens.
Two antigens present in group O streptococci have been described and are designated as type antigens. No other antigens are present in extracts of group O cells in significant quantity. Antigen I is a cell wall protein, and II is a nucleoprotein of undetermined cell location. The immunological specificity of the latter resides only in the protein. Both antigens have been extracted from the cell...
متن کاملSelective streptococcal agar versus blood agar for detection of group A beta-hemolytic streptococci in patients with acute pharyngitis.
In a study on acute pharyngitis in general practice, we compared a selective group A streptococcal agar (ssA) for the recovery of group A beta-hemolytic streptococci (GABHS) with sheep blood agar. All plates were incubated at 36 degrees C in an atmosphere reinforced with 5% CO2 for 48 h with a first reading after 24 h. A total of 197 GABHS isolates were obtained from 721 throat cultures on both...
متن کاملcomparison of excretory-secretory and somatic antigens of ornithobilharzia turkestanicum in agar gel diffusion test
background: ornithobilharziosis as one of the parasitic infections may give rise to serious economic problems in animal husbandry. the aim of the study was to prepare and compare the somatic and excretory-secretory (es) antigens of o. turkestanicum in gel diffusion test. methods: excretory-secretory (es) and somatic antigens of ornithobilharzia turkestanicum were prepared from collected worms ...

Bacteriol. 83:284-296. 1962.-A serological study by agar-gel diffusion of the soluble antigens of 39 strains of the Clostridium perfringens group has shown them to be extremely heterogeneous. Strain variation occurred within th...
