abstract background and purpose: according to the reported problems in area of the inappropriateness of water quality which used for washing and staining of car apparatuses in a car factory, this research was carried out for identification of physical, chemical, and microbiological characteristics of the consumed water in babol car factory, iran. materials and methods: physical and chemical par...

objective:investigating the microbes and interactions of the beneficial symbiotic relationships between the components of the system ecology in the food chains and life cycles is one of the modern sustainable agriculture topics. in this regard, to evaluate the effects of bacteria and vermicompost on morphological characteristics and yield of soybean an experiment was conducted as split plot in ...

background: weissellicin 110 is the only bacteriocin reported in weissella cibaria up to now. this bacteriocin represents several unique features. this is the first report on the gene sequence that encodes for the bacteriocin.objectives: providing a rapid detection method to isolate the weissellicin 110 encoding gene and determination of the bacteriocin distribution were the objectives.material...

results the k. pneumonia isolates were resistant to erythromycin (70%), cefixime (53.3%), tetracycline (50%) and ceftazidime (36.6%). the amplification of teta and tetb genes of k. pneumonia revealed that all of the isolates harbored these genes. conclusions resistance to tetracycline and other antibiotics, and the presence of various resistance genes in k. pneumonia strains are alarming signs ...

two probiotic bacteria (lb. acidophilus and b. lactis) were immobilized on the alginate coat of strawberry pieces and were added to the prepared sweet non fat dietary stirred yogurt. physico-chemical parameters namely ph value, titratable acidity and synersis along with the viability of probiotic bacteria of the samples were evaluated over the 8 days of storage at 5 ºc at 2 day intervals. a sig...

b a ckground: the brown-banded cockroach, supella longipalpa is known as a carrier of pathogenic bacteria in urban environments, but its role is not well documented regarding the carriage of antibiotic-resistant pathogenic bacte- ria in iran. the aim of this study was to determine the resistance bacteria isolated from the brown-banded cockroach in ahvaz, south west of iran. m e t hods: totally ...

b a ckground: microbes particularly bacteria presenting in the gut of haematophagous insects may have an important role in the epidemiology of human infectious disease. m e t hods: the microbial flora of gut and surrounding environmental of a laboratory strain of phlebotomus papatasi , the main vector of zoonotic cutaneous leishmaniasis (zcl) in the old world, was investigated. biochemical reac...

background and objectives : due to the extensive use of antibiotics, the spread of drug-resistant bacteria is one of the most worrisome threats to public health. one strategy that can be used to overcome potential shortcomings might be the inactivation of these organisms by photodynamic therapy. in this study, we have investigated whether drug-resistant wound-associated organisms (staphylococcu...

polycyclic aromatic hydrocarbons (pahs) are one of the most common contaminants found in soil. pahs exhibit a significant concern because of their toxicity, carcinogenic, teratogenic and mutagenic properties. using microorganisms for cleaning the pollution of soil can be cheap, effective and can provide environmental immunity. the goal of this study is to isolate and identify phenanthrene degra...

Although there are many health advantages assigned to different live bacteria such as probiotics, some health threatening effects have also been reported. For example, live bacteria can transfer antibiotic resistance genes to other commensal and opportunistic bacteria of gastrointestinal tract. Recently, it was shown that using killed bacteria have some advantages over live ones. In this resear...
