Impetigo is a common cutaneous infection that is especially prevalent in children. Historically, impetigo is caused by either group A β-hemolytic streptococci or Staphylococcus aureus. Currently, the most frequently isolated pathogen is S. aureus. This article discusses the microbiologic and virulence factors of group A β-hemolytic streptococci and Staphylococcus aureus, clinical characteristic...

SUMMARY The effect of antibiotic prophylaxis in repeat cesarean section were studied in a prospective, double blind clinical trial. 102 pregnant patients with history of previous cesarean section were studied. The partients entered in two groups; A & B: group A were given 2gr cephalosporin and group B 2gr placebo for 3 dose (IV). From 102 patients 48 pt were in group A and 54 were in group B. ...

Background: Hepatitis is among the major health problems, especially in developing countries. During past decades, the association between type of blood group (ABO) and hepatitis B and C virus has always been discussed. This study was designed to investigate the possible association between type of ABO blood group and chronic hepatitis B and C infection. Methods: In the present analytical stud...

Streptococcus agalactiae, also known as group B Streptococcus, is an aetiological agent of urinary tract infection (UTI) in adults, including cystitis, pyelonephritis and asymptomatic bacteriuria (ABU). Whereas ABU-causing S. agalactiae (ABSA) have been shown to grow achieve higher culture denstity human urine compared uropathogenic (UPSA) other phenotypic distinctions between isolated from dif...

Biological activity and presence of DNA sequences related to virulence genes were studied in 21 strains of the Bacillus cereus group. The activity of spent culture supernatants and the effect of infection by vegetative bacterial cells were assessed on cultured human enterocytes (Caco-2 cells). The effect of extracellular factors on the detachment, necrosis and mitochondrial dehydrogenase activi...
