STUDIES OF THE CARRIER STATE FOLLOWING INFECTION WITH GROUP A STREPTOCOCCI. II. INFECTIVITY OF STREPTOCOCCI ISOLATED DURING ACUTE PHARYNGITIS AND DURING THE CARRIER STATE*

Studies of the carrier state following infection with group A streptococci. 1. Effect of climate.

survey of carrier rate of group a hemolytic streptococci

this study was undertaken in order to ascertain the carrier rate of group a hemolytic streptococci in the throats of pupils in selected schools of tehran, and to evaluate the role of socio-economical factors on carrier state. during the period of six months, 7020 children and adolescents, aged 10 to 17, were studied. these pupils were visited at their schools and their socio-economical level wa...

the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.

Survey on Carrier State of Sheep in Chlamydia pecorum Infection

Over the last 40 years, evidence has accumulated to suggest the ubiquitous presence of infections with intracellular bacteria of the genus Chlamydia in different livestock species. Different methods to clinical specimens substantiated such widespread, but mostly clinically unapparent, presumably low-level infections. In this initial epidemiological study, we addressed the question of chlamydial...

Re: role of non-group a streptococci in acute pharyngitis.

BACKGROUND The role of non-group A streptococci (non-GAS) as pathogens of acute pharyngitis is controversial. Data are limited and conflicting on whether these bacteria are true pathogens of pharyngitis and whether treatment is indicated in all cases or just select cases. However, non-GAS are well-documented as being pathogens of other diseases, including neonatal sepsis, pneumonia, endocarditi...
