Three different areas -hospital, food-handling establishments and human dwellings, were surveyed for pathogenic gram-negative bacteria carried on the cuticles of cockroaches. Fifty species of bacteria were identified from all cockroaches. Escherichia coli, Klebsiella pneumoniae, Citrobacter freundii and Enterobacter cloacae were the most frequently found. Pathogenic and potentially pathogenic b...
Antimicrobial resistant zoonotic pathogens present on food constitute a direct risk to public health. Antimicrobial resistance genes in commensal or pathogenic strains form an indirect risk to public health, as they increase the gene pool from which pathogenic bacteria can pick up resistance traits. Food can be contaminated with antimicrobial resistant bacteria and/or antimicrobial resistance g...
Background and purpose: Essential oils are volatile components of plants. Some essential oils with phenolic compounds have a strong antimicrobial properties. Probiotics are live microbial food supplements which beneficially affect host by improving its intestinal microbial balance, and they are well recognized as antimicrobial agents that compete with pathogenic bacteria and inhibit their growth...
BACKGROUND Food-borne pathogens are among the most significant problems in maintaining the health of people. Many probiotics have been widely reported to alleviate and protect against gastrointestinal infections through antibacterial secretion. However, the majority of them cannot always play antagonistic roles under gut conditions. Probiotic bacteria of human origin must possess other protecti...
مروری برآلودگی فراورده های غذایی با منشا دامی به باقی ماندههای آنتی بیوتیکی طی سه دهه اخیر در ایران
Antibiotics residues in animal derived food products are a great concern for public health. The major risk associated with this problem is drug resistance in pathogenic bacteria in consumers.This survey is a comprehensive review of many studies carried out by scientists in Iran in food hygiene, livestock breeding and toxicology over the last thirty years. Food samples were examined by different...
Modern food animal production depends on use of large amounts of antibiotics for disease control. This provides favourable conditions for the spread and persistence of antimicrobial-resistant zoonotic bacteria such as Campylobacter and E. coli O157. The occurrence of antimicrobial resistance to antimicrobials used in human therapy is increasing in human pathogenic Campylobacter and E. coli from...
background: monitoring of indicator and pathogenic microorganisms is essential for proper composting. the aim of this study was to evaluate the change in population of coliform bacteria and salmonella spp. in composting process of municipal wastes and after its application on soil. methods: the samples were taken from each raw waste pile, initial pile, and active phase pile, cooling phase pile ...
objective: microorganisms are responsible for many problems in industry and medicine because of biofilm formation. therefore, this study was aimed to examine the effect of thymus vulgaris (t. vulgaris) extracts on the planktonic form and biofilm structures of six pathogenic bacteria. materials and methods: antimicrobial activities of the plant extracts against the planktonic form of the bacteri...
Foodborne diseases caused by various pathogenic bacteria occur worldwide. To prevent foodborne diseases and minimize their impacts, it is important to inspect contaminated foods and specifically detect many types of pathogenic bacteria. Several DNA oligonucleotide biochips based on 16S rRNA have been investigated to detect bacteria; however, a mode of detection that can be used to detect divers...
Detection of microorganisms such as bacteria and viruses is important in a variety of fields such as bioscience research, medical diagnosis, screening analysis in food processing and for environmental testing. Bacterial contamination of food, water and the environment is on the rise around the globe. The Centers for Disease Control and Prevention (CDC) estimates 76 million food-borne illnesses ...
