This can be confirmed by taking into account the concentration data for the same sample. P. mirabilis causes 90% of all Proteus infections in humans. The literature abounds with studies on the taxonomy of the genusProteus since the original publication by Hauser, who first described the genus (Table 1) (). Thus the increase in total bio-mass in the presence of the antibiotic can be attributed to changing morphology and not to increasing microbe concentration. Proteus mirabilis is a Gram-negative, facultatively anaerobic, rod-shaped bacterium. Microbiology 152: 2149–2157. Proteus mirabilis microbes exposed to amoxicillin/clavulonic acid show the development of both filaments and spheroplasts. It shows swarming motility and urease activity.

Proteus mirabilis is a Gram-negative, facultative anaerobe bacilli, part of the Enterobacteriaceae family, with an ability to ferment maltose and inability to ferment lactose 1).Proteus mirabilis is well-known in clinical laboratories and microbiology survey courses as the species that swarms across agar surfaces, overtaking any other species present in the process. SUMMARY: Microbes were grown on microscope slides so that the growth could readily be observed by phase-contrast microscopy. Having said that, the colony count, the dominant organism and multiple organism all suggest that this is not real urinary infection. The concentration of the two … Helpful, trusted answers from doctors: Dr. Horng on proteus mirabilis morphology: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Proteus mirabilis isolates of different origins do not show correlation with virulence attributes and can colonize the urinary tract of mice.

A P. rettgeri phage (7480 b) is unique in that it possesses a head with a regular hexagonal outline, a collar and a non-contractile tail while a Providence phage (9266) is believed to be the largest phage active on Gram-negative bacteria. A temperate Proteus mirabilis phage (12/57) and a temperate P. morganii phage (10041/2815) differ from phage P22 in that they possess collars. Proteus mirabilis UTI. Current Classification The genus Proteus currently consists of five named species (P. mirabilis, P. penneri, P. vulgaris, P. myxofaciens, and P. hauseri) and three unnamed genomospecies (Proteus genomospecies 4, 5, and 6).. Proteus mirabilis is a type of bacteria that can cause infections in the body, particularly urinary tract infections.
