background: exposure to human blood and body fluids is a common risk for nurses. many factors can affect the prevalence and incidence of this occupational hazard. psychosocial factors at work may be a risk factor for the exposure. objective: to assess needle stick, sharp injury and mucus exposure to blood-borne pathogens among nurses in iran and to determine the association between these exposu...

background the prognostic value of blood culture testing in the diagnosis of bacteremia is limited by contamination. objectives in this multicenter study, the aim was to evaluate the contamination rates of blood cultures as well as the parameters that affect the culture results. materials and methods sample collection practices and culture data obtained from 16 university/research hospitals wer...

conclusions the diagnostics and management of infections with hepatotropic viruses, particularly hbv, are neglected in hemophilic patients. all patients with coagulation disorders and a history of exposure to non-inactivated blood products should be screened for blood-borne infections. the prevalence of other potentially blood-borne viral infections exhibited a pattern similar to that observed ...

a 30-year-old african woman in kenya succumbed to severe swollen regional lymph nodes, development of painful boils and ulcer formation and rashes at specific tick-biting sites together with an intermittent fever and headache following repeated tick bites of rhipicephalus pulchellus. she later developed nuchal lymphadenopathy-like condition and an eschar with edematous margins at bitten sites. ...

Objective: Due to the alarming increase the incidence and prevalence of infectious diseases and increasing bacterial resistance to antibiotics need to discover new strong antimicrobial compounds is feeling.Methods: In this study, the antimicrobial properties of spider silk Pholcus phalangioides produced in sterile conditions against two bacteria, Listeria monocytogenes and <em...

Bacteriophages (also called ‘phage’) were first time isolated in early 1900’s. Until late 1930s, they were used to treat infectious diseases in different parts of the world. Improper use of phages and understandable formulations of phage particles reduced the use of phage therapy association with discovering the antibiotics. In recent years, antibiotic resistance is widespread in the world. Als...

BACKGROUND This study was conducted to examine the frequency of contamination in retail meat available in Karachi, Pakistan. METHODOLOGY Raw meat samples (250) and surface swabs (90) from meat processing equipment and the surrounding environment were analyzed for microbiological contamination. RESULTS Out of 340 samples, 84% were found to be contaminated with bacterial species, including Kl...

Quorum sensing (QS) plays a vital role in regulating the virulence factor of many food borne pathogens, which causes severe public health risk. Therefore, interrupting the QS signaling pathway may be an attractive strategy to combat microbial infections. In the current study QS inhibitory activity of quercetin and its anti-biofilm property was assessed against food-borne pathogens using a bio-s...
