“…First, it may be that this disease is an indirect cause for the relatively high percentage of non-carriers with high serological titres and without previous history of streptococcal infection which our sample presents (17 % at least). As a matter of fact, though we have very few comparative studies of the same kind in "normal" populations this percentage is somewhat higher than in the studies of Streitfeld (8.6 %) [ll], but consistently lower than in that of Packer (25%) [9]. This serological rise may be attributed to extra pharyngeal infective sites, although this hypothesis is very difficult to prove bacteriologically.…”

Summary A longitudinal study has been conducted on 114 children in a hospital for primary tuberculosis, in order to determine the incidence of Group A latent streptococcal infection. The subjects were regularly examined for the presence of Group A streptococcus in the throat, the level of streptococcal antibodies in the sera; a daily methodical investigation was also performed in the search of any clinical symptoms of infection. The analysis of the modes of infection shows that several degrees exist between the subject remaining free of any contact with group A streptococcus and that one who presents a clinically acute infection; some children are truly healthy carriers, but more frequently the acquisition of the germ is followed by a rise of serological reactions. This infection may be clinically latent, 01: may show Clinical Symptoms of disease. Children classified as chronic carriers may harbour a single type of streptococcus or two or more types which may or may not be present concurrently within the carrier.

“…In the study of Siegal et al (21) group A was found in 47.7%; for Mocfet et al (13), it was 50%; and for Koshi et al (9), 31.2%. Group C and G streptococci have been incriminated in upper respiratory tract infections (5,7,10,11,17,22,26). Koshi et al (9) found group C and G in 22.9% and 28.4% of their isolates respectively.…”

Two hundred and twenty four hospitalized children in Baghdad aged between 1 month and 10 years were examined for Streptococcal infections. Thirty‐four percent of the throat and saliva specimens were positive for β‐hemolytic streptococci. Males were more susceptible to infection with group A streptococci than females. Streptococcus of group A was isolated from 39.5% of the positive cases while group G was 47.4%. The etiological significance of the latter group in tonsillitis and otitis media is to be further investigated. Ninety six percent of the isolated streptococci were T typable and 13.3% of the strains were M typable. A high frequency of type T‐11 was found in streptococcal infections. T type 3875 was found to be a new provisional type. All isolates were M untypable, and anti‐opacity factor negative except for two isolates of T type 4 which were positive in both typings.
