background: urinary tract infection (uti) is considered as the most common bacterial infectious disease seen among the pediatric patients. the aim of this study was to investigate the prevalence and antimicrobial susceptibility of bacterial uropathogens isolated from the pediatric patients with urinary tract infections. methods: this descriptive study was conducted in children medial center, te...
Invasive infection with Gram-positive and Gram-negative bacteria often results in septic shock and death. The basis for the earliest steps in innate immune response to Gram-positive bacterial infection is poorly understood. The LPS component of the Gram-negative bacterial cell wall appears to activate cells via CD14 and Toll-like receptor (TLR) 2 and TLR4. We hypothesized that Gram-positive bac...
Abstract Objective: To assess the incidence of thrombocytopenia and changes in various platelet parameters, in culture positive neonatal sepsis. Methods: This was prospective study conducted over a period of one year from December 2009 to November 2010 in neonatal intensive care unit of DDUH Hospital, a tertiary care hospital in Delhi, North India. All babies who were admitted during this perio...
Abstract Background and Objective: Neonatal sepsis is a remarkable factor in mortality, morbidity, neonatal and perinatal complications. Group B Streptococcus (GBS) is the primary cause of invasive disease in infants and pregnant women. This study aimed to determine the relationship between antimicrobial resistance of the bacteria colonized in the vagina and rectum of pregnant wome...
Introduction: Bile duct obstruction due to gall stone is the most common cause of biliary infection. Bacteria stabilize during the inflammation of gallbladder and it is confirmed that longer duration of inflammation is associated with more risk of post operative infection. In this study we sought to determine the biliary microbial flora in patients with acute and chronic cholecystitis in orde...
The basic polyamine spermine was tested for antibacterial activity at two pH levels by the modified cup method against a variety of gram-positive and gram-negative organisms isolated from urine. At pH 6.4, with concentrations ranging from 39 to 2,500 mug per 0.1 ml, there were no clear zones of inhibition seen with any of the gram-negative test organisms, although some adverse effect on growth ...
background: many efforts have been done to find effective agents against resistant pathogens. cuminum cyminum l. (cumin) is an aromatic plant within the apiaceae family. it has a variety of purposes and demonstrates antimicrobial and antioxidant properties. this study evaluated the activity of c. cyminum extract and essential oil against bacterial isolates which cause urinary tract infection, i...
abstract background: streptococcus mutans in the oral cavities sable to produce mutacin (bacteriocin-like substances) with antibiotic properties. the aim of this study was to investigate the frequency and expression of genes encoding mutacins typei, ii, iii and iv and also two of 8 genes in a cluster encoding the putative bacteriocins, the designated bsm 283, bsm 299, bsm 423, bsm 1889c, bsm 18...
Background: Post-neurosurgical meningitis is a significant cause of mortality and morbidity. In this study we aimed to compare the differences of clinical, laboratory features and outcomes between the post-neurosurgical meningitis caused by gram-negative bacilli (GNB) and gram-positive cocci (GPC). Methods: Cases of post-neurosurgical meningitis (with positive CSF culture) were included. After...
