BACKGROUND Here we report a rare case of lumbar spine epidural abscess and facet joint septic arthritis caused by Streptococcus agalactiae, which had spread to the iliopsoas muscles, leading to urine retention. CASE PRESENTATION A 68-year-old woman with low back pain experienced a sudden onset of bilateral lower limb weakness, it was followed 14 days later by urine retention. At consultation,...

It is generally accepted that the composition of the medium exerts an important influence on the action of antibacterial substances on microorgani. Many workers have succeeded in paralyzing the effect of antibacterials by the addition to the media of substances such as organ extracts, peptone, and bacterial extracts. Thus, Mcllwain (1941) counteracted the antibacterial effect of acriflavin on E...

Cases of liver abscess complicated by portal vein thrombosis are relatively rare. We report a case of liver abscess caused by α-hemolytic streptococci and complicated by portal vein thrombosis. A 51-year-old male presented with fever and right hypochondralgia. He had watery diarrhoea and bloody stool for over 1 month before presentation. Laboratory tests showed elevated hepatobiliary enzymes, i...

From one strain of hemolytic streptococcus three forms were isolated, which produced three different degrees of hemolysis on the surface of blood agar in the presence of oxygen. The original form was moderately hemolytic; the glossy variant was more hemolytic than the original form; and the third form, obtained by passing the original culture through mice, was non-hemolytic. Under anaerobic con...

in a clinical trial a new pyrrolidonyl-β-naphthylamide (pyr) hydrolysis test was compared with the bacitracin disk susceptibility test for accuracy in the presumptive identification of group a streptococci (gas). among 128 isolates of beta-hemolytic streptococci 93 group a isolates were found. the sensitivity of the pyr and bacitracin tests were similar (98.9%), but the bacitracin test had a lo...

1. The relation between hemolytic and non-hemolytic streptococci is orderly and arises from the fact that the former variety is unique while the latter is heterogeneous. 2. Analogous considerations of the classification, distribution, and pathogenicity of the streptococcus group and the pneumococcus and colon-typhoid groups show a definite parallelism. 3. These considerations suggest that uniqu...

Streptococcal disease and columnaris are common in tilapia aquaculture across the globe. Coinfections also but often overlooked or not reported. In present study, we describe clinical presentation of streptococcosis coinfection diseased Nile ( Oreochromis niloticus ), phenotypic (Lancefield grouping, hemolytic pattern, biochemical characteristics, antibiotic susceptibility) genotypic (multilocu...
