Antibiotics have been used to maintain the overall health of poultry by increasing production efficiency, promoting growth, and improving intestinal function for more than 50 years. However, they a number side effects, such as antibiotic resistance, gut dysbiosis, destruction beneficial bacteria, potential spread diseases humans. In order address aforementioned issues, lot effort is put into de...

Incomplete treatment of patients with infectious tuberculosis (TB) may not only lead to relapse but also to the development of antibiotic resistant TB-one of the most serious health problems facing society today. In this article, we formulate one-strain and two-strain TB models to determine possible mechanisms that may allow for the survival and spread of naturally resistant strains of TB as we...

This study examined culturable skin microbiota that was associated with farmed European seabass (Dicentrarchus labrax). Healthy were sampled during summer commercial harvest from one conventional fish farm where antibiotics are used, and another practicing a certified antibiotic-free aquaculture. Physicochemical microbiological analysis of seawater sediment performed, as well determination bact...

OBJECTIVES The use of antibiotics for the treatment of infectious diseases has led to important changes in the structure of pathogenic bacterial populations. However, these changes could be buffered if the expression of antibiotic resistance genes were to lead to the counter-selection of antibiotic-resistant strains in antibiotic-free environments. To test the effect of antibiotic resistance on...

conclusions our findings indicate that probiotic bacterial strains of lactobacillus have a significant inhibitory effect on the growth of p. aeruginosa ptcc 1430. the antimicrobial potency of this combination can be useful for designing and developing alternative therapeutic strategies against p. aeruginosa infections. results the results showed a significant effect of cfs on the growth of p. a...

patients and methods two-hundred and fifty-five clinical specimens were collected from four major provinces of iran. samples were cultured and the mrsa strains were subjected to polymerase chain reaction (pcr). the patterns of antibiotic resistance were determined using the disk diffusion method. results seventy-four out of 255 (29.01%) clinical samples were positive for mrsa. of the 74 mrsa st...
