Acridine-resistant mutants of T2H bacteriophage.
mechanisms which prevent formation of infective T2H bacteriophage in T ~ c h r i c h i a coli in the presence of acridine dyes are unknown. That interruption of normal maturation occurs in a late stage of phage development was suggested by the work of FOSTER (1948) and has been substantiated physiologically and cytologically. DEMARS, LURIA, FISHER and LEVINTHAL ( 1953) and DEMARS (1955) found i...
متن کاملAntimicrobial-resistant enteric bacteria from dairy cattle.
A study was conducted to understand the descriptive and molecular epidemiology of antimicrobial-resistant gram-negative enteric bacteria in the feces of healthy lactating dairy cattle. Gram-negative enteric bacteria resistant to ampicillin, florfenicol, spectinomycin, and tetracycline were isolated from the feces of 35, 8, 5, and 42% of 213 lactating cattle on 74, 39, 9, 26, and 82% of 23 farms...
متن کاملAntibiotic-Resistant Enteric Bacteria in Environmental Waters
Sources of antibiotic resistant organisms, including concentrated animal feeding operations (CAFOs), may lead to environmental surface and groundwater contamination with resistant enteric bacteria of public health concern. The objective of this research is to determine whether Salmonella, Escherichia coli, Yersinia enterocolitica, and enterococci resistant to clinically relevant antibiotics are...
متن کاملBacteriophage-resistant and bacteriophage-sensitive bacteria in a chemostat.
In this paper a mathematical model of the population dynamics of a bacteriophage-sensitive and a bacteriophage-resistant bacteria in a chemostat where the resistant bacteria is an inferior competitor for nutrient is studied. The focus of the study is on persistence and extinction of bacterial strains and bacteriophage.
متن کاملVirulence reduction in bacteriophage resistant bacteria
Bacteriophages can influence the abundance, diversity, and evolution of bacterial communities. Several bacteriophages have been reported to add virulence factors to their host and to increase bacterial virulence. However, lytic bacteriophages can also exert a selective pressure allowing the proliferation of strains with reduced virulence. This reduction can be explained because bacteriophages u...
