Although antibiotic-resistant pathogens pose a significant threat to human health, the environmental reservoirs of the resistance determinants are still poorly understood. This study reports the detection of resistance genes (ermB, mecA, mupA, qnrA, qnrB and tetL) to antibiotics among certain culturable and unculturable bacteria associated with the marine sponge Petromica citrina. The antimicro...

Antibiotics, disinfectants and bacteria resistant to them have been detected in environmental compartments such as waste water, surface water, ground water, sediments and soils. Antibiotics are released into the environment after their use in medicine, veterinary medicine and their employment as growth promoters in animal husbandry, fish farming and other fields. There is increasing concern abo...

Background and Objective: Antibiotic resistance is the ability of microbes to survive antibiotic exposure with standard doses. Regular updating of antibiotics is one solution to overcome antibiotic resistance. One source with potential new antibiotics is moonmilk from caves because it contains various bacteria proven to have antibacterial activity. The objective of the present study is to explo...

Shrimp farming is a sufficiently large and mature industry to have an effective range of antimicrobial agents for most bacterial diseases in shrimp culture. However, at present, there exists great concern over the widespread use of antibiotics in aquaculture, which may result in residue of antibiotics in water and mud, and subsequently, the development of antibiotic resistance in bacteria in th...

There is concern that antibiotic resistance can potentially be transferred from animals to humans through the food chain. The relationship between specific antibiotic resistant bacteria and the genes they carry remains to be described. Few details are known about the ecology of antibiotic resistant genes and bacteria in food production systems, or how antibiotic resistance genes in food animals...

Introduction: Diffusion of antibiotic resistance genes by horizontal gene transfer has led to the fast emergence of multidrug resistance (MDR) among bacteria. Multiple classes of integrons are effective genetic elements which play a significant role in the acquisition and nosocomial dissemination of resistance factors in strains of Gram-negative bacteria, Pseudomonas aeruginosa, and Acinetobact...

Misuse of antibiotics in humans and animals often leads to the development ofmultidrug resistance (MDR)bacteria. Resistance can occur within a few years of novel antibiotics being introduced. Lytic bacteriophage (phage) are a kind of virus that undergo a cyclical lifestyle wherein they infect and replicate through the use of a bacterial host cell and cause cell lysis. Phage recognizes specific ...

Antibiotic resistance thwarts the treatment of infectious diseases worldwide. Although a number of factors can be identified which contribute to the problem, clearly the antibiotic as a selective agent and the resistance gene as the vehicle of resistance are the two most important, making up a 'drug resistance equation'. Both are needed in order for a clinical problem to arise. Given sufficient...

Resistance to bile acids is a necessary ability for bacteria that live in the gastrointestinal tract, such as Helicobacter pylori. The role of bacterial drug efflux system important acid tolerance. Using H. pylori JP26 strain and JP26AcrB deficient AcrB relationship between tolerance was investigated. Bacterial susceptibility measured by agar dilution method. To examine acids, intracellular acc...

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 esherichia coli with ...
