Streptococcus agalactiae is a significant Gram-positive bacterial pathogen of terrestrial and aquatic animals. A subpopulation of nonhemolytic strains which appear to be pathogenic only for poikilotherms exists. We report here the first draft genome sequence of a nonhemolytic S. agalactiae isolate recovered from a diseased fish.
Chylothorax is bacteriostatic in nature. Bacterial infection rarely develops in chylothorax and has never been reported in a non-immunocompromised host. A 33-year-old woman was admitted to National Taiwan University Hospital because of fever and right pleuritic pain. Chest roentgenography and computed tomography revealed right pleural effusion. Examination of the pleural effusion revealed a pro...
The purpose of this study was to identify the major etiological agents responsible for invasive bacterial infections in immunocompetent Korean children. We retrospectively surveyed invasive bacterial infections in immunocompetent children caused by eight major pediatric bacteria, namely Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis, Staphylococcus aureus, Streptococcu...
The activity of tigecycline was tested against erythromycin-resistant streptococci (107 Streptococcus pyogenes and 98 Streptococcus agalactiae strains). The presence of erythromycin and tetracycline resistance genes was determined by PCR. Among S. pyogenes strains the most prevalent gene was mef(A) (91.6%). The erm(B) gene was the most prevalent (65.3%) among S. agalactiae strains. Tigecycline ...
Streptococcus agalactiae is an important microorganism involved in a number of conditions in pregnant women, newborns, elderly people (over 65 years of age) and individuals with chronic disabling illnesses. This pathogen is infrequently found among patients outside this age range or clinical profile(1-5) and is rarely reported in the etiology of sexually transmitted diseases. Here we describe a...
this study was conducted to detect the common bacteria implicated in bovine mastitis in bulk tank milk by polymerase chain reaction (pcr). forty-four milk samples from bulk tank milk were obtained and submitted to our laboratory. to detect staphylococcus aureus, streptococcus agalactiae, streptococcus dysgalactiae, escherichia coli, streptococcus uberis, and streptococcus parauberis, two sets o...
Thirty-five putative integrative conjugative elements and related elements were identified at 15 locations in the eight sequenced genomes of Streptococcus agalactiae. Twelve are composite, likely resulting from site-specific accretions. Circular forms were detected for five elements. Macroarray analysis confirmed their high plasticity and wide distribution in S. agalactiae.
Clinical isolates of Gardnerella vaginalis, Streptococcus agalactiae, Bacteroides spp., and Mobiluncus spp. were screened for resistance to tetracycline and for the presence of the streptococcal tetM determinant. The S. agalactiae and G. vaginalis strains contained DNA sequences homologous to the tetM determinant, while strains of the other two genera did not.
This study investigated the in vitro activity of gemifloxacin (SB-265805) against 50 recent clinical isolates of Streptococcus pyogenes, Streptococcus agalactiae and viridans streptococci using the microdilution method. This activity was compared with that of the quinolone agents ofloxacin, ciprofloxacin, levofloxacin, trovafloxacin and grepafloxacin, and with that of penicillin, ampicillin, cl...
conclusions bacterial resistance against chlorhexidine is increasing. sub-mic doses of chlorhexidine digluconate can stimulate the formation of biofilm strains. materials and methods forty clinical isolates of escherichia coli, salmonella serotypes, staphylococcus. aureus and streptococcus agalactiae (10 isolates for each) were examined for chlorhexidine digluconate effects on biofilm formation...
