We describe a case of culture-negative meningitis and endocarditis caused by Streptococcus agalactiae in a 27-day-old boy. S. agalactiae was detected in cerebrospinal fluid and serum by broad-spectrum PCR amplification.

Through the selection of resistance to sparfloxacin, an attenuated Streptococcus agalactiae strain, 138spar, was obtained from its virulent parent strain, S. agalactiae 138P. The full genome of S. agalactiae 138spar is 1,838,126 bp. This genome will allow comparative genomics to identify genes associated with virulence, antibiotic resistance, or other characteristics.

The effectiveness of a teat dip with dodecyl benzene sulfonic acid (1.94%) for the prevention of intramammary infections was determined in cows experimentally challenged with Streptococcus agalactiae and Staphylococcus aureus. The infection rates with Streptococcus agalactiae and Staphylococcus aureus were 62.5% and 75% in undipped quarters, 12.5% and 21.5% in dipped quarters with a reduction r...

Streptococcus agalactiae is a major contagious pathogen causing bovine mastitis worldwide. We report here the draft sequence of S. agalactiae Ia strain M19, a multidrug-resistant isolate from a bovine mastitis case in Ningxia Hui autonomous region, China.

Streptococcus agalactiae causes a range of clinical syndromes in camels (Camelus dromedarius). We report the genome sequences of two S. agalactiae isolates that induce abscesses in Kenyan camels. These genomes provide novel data on the composition of the S. agalactiae "pan genome" and reveal the presence of multiple genomic islands.

alpha toxin derived from clostridium perfringens was used for diagnosis of streptococcus agalactiae (st.agalactiae) by rapid and spot camp tests. the selected cl.perfringens strain was cultured in optimized conditions; the supernatant of culture was concentrated by ultra filter and purified by deae cellulose chromatography. the efficacy of both purified and crude α-toxins were examined by rapid...

Streptococcus agalactiae, a unique bacterium commonly referred to as group B streptococcus (GBS), is evolving to become a major pathogen that causes a wide variety of problems across a broad spectrum of individuals. The greatest controversy over this bacterium involves the obstetrical patient. Lawyers have made this organism a centerpiece, leading their clients to believe that the presence of G...

Whole-cell protein electrophoretic analysis of the type strain of Streptococcus difficile (LMG 15799) revealed that this organism was indistinguishable from Streptococcus agalactiae strains. Although LMG 15799T (T = type strain) was originally described as serologically untypeable, we found that this strain was a group B streptococcus belonging to the capsular polysaccharide antigen type Ib gro...

Adults with chronic immunosuppressive conditions are at an increased risk for Streptococcus agalactiae endocarditis, which is typically characterized by acute onset, presence of large vegetations, rapid valvular destruction and frequent complications. We report a rare case of a 74 years old man presenting with fever, renal infarction, ischemic stroke and uveitis. Infective endocarditis was diag...
