Aeromonas species, aquatic Gram-negative bacilli, distributed globally and ubiquitously in the natural environment, may be implicated in a variety of human diseases. They can produce various β-lactamases which confer resistance to a broad spectrum of β-lactams, and therefore in vitro susceptibility testing must be used to guide antimicrobial therapy. However, conventional in vitro susceptibilit...

I the management of pseudomonal infections, carbapenems are among the most potent and the last-line of antibiotics. Therefore, reliable in vitro susceptibility testing of the clinical isolates of Pseudomonas aeruginosa (P. aeruginosa) against carbapenems is of paramount importance for the healthcare outcome.1 However, in the post-market evaluations, it has been demonstrated that not all the tes...

abstract background: the invasion of microorganisms into the bloodstream and spread to different parts of body can cause disruption the functions of vital organs and even death. the proper and prompt treatment is essential and can significantly reduce morbidity and mortality rates. this study aimed to determine the frequency and the antimicrobial susceptibility of bacteria isolated from blood c...

Tritrichomonas foetus KV(1), a nitroimidazole-susceptible strain, and KV(1)/M100, its nitroimidazole-resistant daughter strain, differed markedly in their in vivo susceptibility to metronidazole. In vitro susceptibility testing in multiwell plates and tubes with different trichomonad media containing no, or low concentrations of, ascorbate demonstrated that the resistant strain behaves like the...
