conclusions the bacterial isolates exhibited strong biofilm formation potential, while the extracts of acacia arabica significantly inhibited biofilm formation among the isolates and, therefore, could be executed in the development of cost-effective biofilm inhibitor medicines. results pseudomonas aeruginosa (kc417303-05), staphylococcus hemolyticus (kc417306), and staphylococcus hominis (kc417...

background: resistance to anti-tuberculosis (tb) drugs is a global problem. previous studies showed that the prevalence of primary mdr-tb is higher and has been increasing. the purpose of this study was to determine the primary drug resistance in strains isolated from patients with smear-positive of the new cases to anti-tb drugs. methods: in this cross-sectional study, 266 smear positive pulmo...

conclusions despite implementation of community-level harm reduction strategies in iran, infectious complications due to illicit drug use are frequent and often require care at the hospital. introducing harm reductions services at an inpatient level may improve the quality of care provided and help reduce the burden of accrue from drug use. background infectious complications among injection dr...

discussion: the present case demonstrates that the uropathogenic e. hermanii clone can cause destruction of the kidneys. during asymptomatic bacteriuria or cystitis, the bacteria remain in the urinary tract. even when pyelonephritis develops, inflammatory response of the host is still restricted to the urinary tract. these signs mean that uropathogenic e. hermanii may be not very virulent. intr...

the chemical composition of essential oils isolated from the leaves of cosmos bipinnatus and its antibacterial activity were analyzed by gc-ms and microbroth dilution assay respectively. the essential oil extracted from this plant was predominantly composed of monoterpenes (69.62%) and sesquiterpenes (22.73%). the antibacterial assay showed that the oil had significant inhibitory effects agains...

results patients between 35 and 44 years of age were most frequently affected (25.00%) by otitis externa (average age, 43.87 ± 18.08 years). moreover, women (54.31%) were more frequently affected than men (45.69%). upon direct investigation, gram-positive bacilli were the most commonly identified microorganisms (22.41%). furthermore, bacillus spp. and coagulase-negative staphylococci (22.41% an...

background: neutropenic patients are vulnerable to a wide spectrum of infectious agents. the aim of this study was to determine the current frequency of bacterial infections in patients with nosocomial fever and neutropenia. methods: in a retrospective study, the neutropenic patients’ specimens with nosocomial fever were cultured on blood and macconkey agar plates and evaluated at microbiology ...

results out of 2229 suspected meningitis cases, 255 (11.4%) were detected as positive culture. most of the isolates were gram-positive cocci, which 116 (45.5%) were staphylococcus epidermidis, and 20 (7.8%) identified as streptococcus spp. among gram-negative isolates, escherichia coli and acinetobacter spp., each with 19 isolates (5.9%), were predominant. overall, the most effective antibiotic...

background: lower respiratory tract infections (ltris) are among the most common infectious diseases with potential life-threatening complications. methods: the study consisted of 426 patients with suspected ltris from mid and far western region of nepal between september 2011 and july 2014. the specimens were collected and processed according to the standard microbiological methods at the cent...
