Prevalence of Parasitic Intestinal Infections Among Food Handlers in Qazvin, İran

Prevalence of Parasitic Intestinal Infections Among Food Handlers in Qazvin, İran Turkiye Parazitol Derg. 2019 Mar 28;43(1):16-20 Authors: Shahnazi M, Sadeghi M, Saraei M, Alipour M, Hajialilo E Abstract Objective: Food handlers play an important role in the production and distribution of parasitic contaminations in these societies. The aim of this study was to assess the prevalence of intestinal parasitic infections among the food handlers in Qazvin, Iran. Methods: Totally, 1530 stool samples were collected from food handlers in Qazvin, Iran. Direct feces examination and formalinethyl acetate concentration method followed by Trichrome staining were performed to detect the parasites. Results: The prevalence of intestinal parasites was 82 (5.4%) among food handlers. The species of protozoan parasites found were Blastocystis hominis, Giardia lamblia, Entamoeba coli, and Endolimax nana. The outbreaks of Blastocystis hominis (2.9%), and Endolimax nana (0.3%) were the most and the least protozoan infections observed among the specimens, respectively. Also, there was no helminthic infection detected among the samples. The prevalence of intestinal parasites among the food handlers, based on variables including sex, age, job, and education, did not differ, whereas the prevalence of intestinal symptoms was shown to be higher in infected food handlers (p

In order to understand the effect of microorganisms, the study of their characteristics and behavior in various platforms is of prime importance. Over the years, time-consuming and labor-intensive, culture-based enumeration techniques have become obsolete for real-time applications, and increasing concerns on foodborne outbreaks necessitate rapid, on-site and sensitive methods for the detection ...

The objective of this study was to evaluate the effectiveness of pulsed light (PL) treatment, a novel antimicrobial (LAPEN) wash and combinations thereof in inactivating Salmonella on stem scars of cherry tomato. The treatment effects on background microbiota and sensory quality was also investigated while in storage for 21 days at 10 °C. Three serotypes of Salmonella enterica were chosen to prepare inoculum for the current investigation for their link with tomato and produce outbreaks. Stem scars of tomato were spot inoculated before being treated with PL (1–63 J/cm2), LAPEN sanitizer (2 min) or combinatio...

Authors: Gatti M, Raschi E, De Ponti F Abstract BACKGROUND: The management of Klebsiella pneumoniae carbapenemase producing (KPC) infections represents a major challenge. Several safety and efficacy concerns are shared by available antibiotics used in KPC infections, leading to the occurrence of serious adverse drug reactions (ADRs), with ceftazidime-avibactam possibly showing a more favourable risk-benefit profile. We investigated the potential impact of resistance on ADR reports in countries with different prevalence of KPC isolates (Italy vs. United Kingdom [UK]), and described safety profile of newer and older ...

Galectin-2 (Lec-2), a major component of Brugia malayi extracellular vesicles, is released by filarial worms, and was recently identified in the serum of persons with loiasis. We therefore sought to clone and characterize Lec-2, and to develop reagents to examine its potential as a biomarker and its role i...

The substrate specificity of RhlI, an enzyme in the RhlI–RhlR quorum sensing system of Pseudomonas aeruginosa, was explored by directed evolution to gain insight into the molecular mechanisms of quorum sensing. RhlI catalyzes S-adenosyl methionine and butanoyl or hexanoyl acyl carrier protein to form N-butanoyl...
