The bacteria Streptococcus thermophilus belongs to the group of lactic acid bacteria, where the research aims to identify the role of Biosurfactant produced from the bacteria Streptococcus thermophiles for its importance in limiting the growth of Staphylococcus aureus and its effect on some of the physiological parameters of the white rats male ، Streptococcus thermophilus were isolated from local white cheese, and then 120 clinical samples (Wounds, Burns, Blood) were collected. Biosurfactant was extracted from Streptococcus thermophilus and its inhibitory activity was evaluated against Staphylococcus aureus. As well as, its resistance to some antibiotic effects was studied and the effect of Biosurfactant on some physiological parameters in white rats male. ،22 infected samples were obtained, distributed between (11,8, and 3) for each of the (Wound, Burn, and Blood) samples, respectively. The results also showed resistance of bacteria S. aureus to some of the antibiotics used in the study, the results of the statistical analysis to evaluate the inhibitory activity of the Biosurfactant towards S. aureus showed a significant increase at a significant level (P

Characteristics of CDC group 1 and group 1-like coryneform bacteria isolated from clinical specimens
Fifteen strains of CDC group 1 coryneform and biochemically similar bacteria were isolated from clinical specimens. Of the 15 strains isolated, 11 were derived from abscesses and purulent lesions, mostly from the upper part of the body, and 3 were grown from blood cultures. Nine strains were associated with mixed anaerobic but no other aerobic flora. Seven strains exhibited the classical biochemical profile of CDC coryneform group 1; however, eight strains were unable to reduce nitrate and were called "group 1-like." Other reactions to differentiate CDC group 1 and group 1-like coryneform rods include alpha-hemolysis on human blood agar, fermentation of adonitol, and the presence of alkaline phosphatase. Fifteen strains showed marked CAMP reactions on different erythrocyte agars. Gas-liquid chromatography of volatile and nonvolatile fatty acids as well as cellular fatty acid patterns and the composition of cell wall components suggest that CDC group 1 and group 1-like coryneform bacteria do not belong to the genus Corynebacterium but possibly to the genus Actinomyces or Arcanobacterium. DNA-DNA hybridization studies revealed that group 1 and group 1-like strains represent different species.

Purulent exudate from 28 cases of Bartholin's abscess were examined for aerobic, anaerobic, and microaerophilic bacteria. Three cases gave no bacterial growth, five cases grew facultative bacteria only, and a further three grew a mixture of facultative and anaerobic bacteria. One case gave a pure growth of a microaerophilic streptococcus. Anaerobic bacteria were the only isolates in 16 cases and Bacteroides species were the most common organisms isolated; they were present as 62.5% of the total anaerobes cultured and accounted for 45.4% of the total bacteria cultured. Escherichia coli was the most common of the facultative organisms, accounting for 18% of the total bacteria. Most infections seemed to be caused by a single organism, anaerobic types predominating.

Twenty‐one rejected kidneys from 2426 slaughtered dairy cows (0·87 per cent) had gross signs of pyelonephritis that were confirmed by histopathology. In all the kidneys the findings were consistent with a chronic rather than an acute infection. One species of bacteria was cultured from 12 of the kidneys and two species of bacteria were cultured from six. The most commonly isolated bacteria were Escherichia coli , from eight kidneys, Arcanobacterium pyogenes , from seven kidneys and Corynebacterium renale , from five kidneys. The other bacteria cultured were Corynebacterium cystitidis , Corynebacterium species, Streptococcus species group G and Enterococcus faecalis . E coli was cultured from all the kidneys from which two species were isolated; the accompanying bacteria were A pyogenes in three kidneys, C renale in two and C cystitidis in one. No bacteria were cultured from two of the kidneys and no significant bacteria were cultured from another. The kidneys with pyelonephritis were slightly larger than a comparison group of 72 kidneys without nephritis.

Uptake by mouse polymorphonuclear leukocytes (PMNs) of piliated (P+) and non-piliated (P-) bacteria of Corynebacterium renale strain No.115 was studied. P+ bacteria were significantly less phagocytized than P- bacteria by PMNs in the absence of opsonins, in the presence of 5% complement alone, and in the presence of either anti-pili serum alone, anti-P+ bacteria serum alone or anti-P- bacteria serum alone. Uptake of P+ bacteria was enhanced and became nearly equal to P- bacteria in the presence of anti-pili serum plus complement and in the presence of anti-P+ bacteria serum plus complement. The anti-pili monoclonal antibodies 16/5 and 13/4 were opsonic, regardless of the pressence of complement, for P+ but not P- bacteria, but there was less effect than that of anti-pili polyclonal antibody plus complement. Uptake of P- bacteria in the presence of opsonins was similar to that in the absence of opsonins.

Aspirates have been cultured from 10 dental abscesses of endodontic origin, all of which had penetrated beyond the bony alveolus to produce fluctuant swelling. Sampling was by syringe aspiration. Strict anaerobic techniques, including the use of an anaerobic chamber, were used for serial dilution and plating. Randomly selected colonies (100) from each culture were purified, characterized, and identified. Seventy percent of the bacterial isolates were either strict anaerobes or microaerophilic. One abscess yielded a pure culture of a viridans streptococcus, Streptococcus milleri. Streptococcus intermedius dominated the flora in a second abscess. The common oral streptococcus, Streptococcus sanguis, constituted only 2% of the isolates from one additional infection. Fusobacterium nucleatum, Bacteroides melaninogenicus, other Bacteroides including B. oralis and B. ruminicola, anaerobic diphtheroids, Peptostreptococcus micros, and Staphylococcus epidermis were other predominant isolates.

A strain of Streptococcus salivarius, recognized in a throat culture because of its inhibition of the growth of a species of Corynebacterium, was studied in vitro to determine its antagonistic effects against various other bacteria. It was found to be inhibitory to anaerobic Gram-positive cocci, streptococci belonging to Lancefield's groups A, C, F, and G, and Corynebacterium diphtherial, C. hofmanii, and C. xerosis.
