Objective Little attention has been given to acute hematogenous osteomyelitis (AHO) caused by group A -hemolytic Streptococcus (GABHS), although up to 10% of cases are caused by this microorganism. The objective of this study was to define the clinical and laboratory characteristics of AHO caused by GABHS. Methods. Between January 1983 and June 1999, 29 patients were treated at Children’s Natio...

BACKGROUND The presumed ascending route of group B beta-hemolytic streptococcus (GBS) infection from the colonized maternal genital tract is well accepted. This case report proposes a hematogenous, selective infection of one unruptured amniotic sac over the other ruptured amniotic sac in a twin gestation in a patient with known GBS vaginal colonization. CASE This is a case report of GBS sepsi...

Group D streptococci isolated from clinical specimens and from sewage were investigated with regard to resistance to tetracycline (Tc), erythromycin (Em), and chloramphenicol (Cm). The median values of the percentages of resistant strains from sewage were: for Tc, 14%; for Em, 2.8%; and for Cm, 0.1%. For the recent isolates of clinical origin, resistance percentages found were 58% for Tc, 12% f...

OBJECTIVES To report the pharyngeal colonization rate of β-hemolytic streptococci and changes in the value of antistreptolysin O (ASO) and anti-DNase B serology titers during pregnancy. METHODS Healthy pregnant women were recruited and blood was drawn in each trimester. The upper limit of normal (ULN) values for ASO and anti-DNase B was calculated for each trimester. Throat swabs were collect...

I t has often been noted that on a blood agar plate seeded with influenzal sputum the colonies of Bacillus influenz6e are most numerous and grow to larger size in the neighborhood of colonies of certain other organisms, notably the staphylococcus. This phenomenon led the authors to conduct various experiments which may be summarized as follows: Blood agar plates were seeded uniformly with a pur...

Omadacycline is the first intravenous and oral 9-aminomethylcycline in clinical development for use against multiple infectious diseases including acute bacterial skin and skin structure infections (ABSSSI), community-acquired bacterial pneumonia (CABP), and urinary tract infections (UTI). The comparative in vitro activity of omadacycline was determined against a broad panel of Gram-positive cl...

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...
