Thirteen of 14 patients prospectively cultured were colonized by the epidemic organism in the intestinal tract, while rectal carriage preceded infection by the same strain in at least four patients. Under the microscope it is rod shaped, motile (can move due to its flagella) and has a characteristic swarming ability that allows it to migrate across catheter surfaces (Armbruster 2013). Only the number of operations (P < 0.01) and proximity to another case (P < 0.05) remained significant risk factors when related parameters were controlled by multivariate analysis. Proteus is a gram-negative, anaerobic bacterium of the Enterobacteriaceae family (Brooker 2008). Case-control analysis indicated a significantly increased risk of infection related to length of hospital stay (P <0.005), number of operations (P < 0.005), proximity to another case (P < 0.01), number of antibiotics received (P < 0.02), and use of a respirator (P < 0.01). Clinical features appeared as early as day 6 of life, and with no evidence of ear, sinus or urinary infections, ascending maternal transmission is the most.
No common source of infection was identified, and person-to-person transmission was the most likely mode of spread. inase-producing Proteus mirabilis and Providencia stuartii and multidrug-resistant Pseudomonas aeruginosa susceptible only to polymyxin and fosfomycin were.
An outbreak of nosocomial infections involving an unusual strain of multiply resistant Proteus mirabilis (phage type 8888) occurred in 15 patients, 14 of whom were in the surgical intensive care unit at that time. Nineteen multidrug-resistant Proteus mirabilis strains were isolated from 19 patients suffering from infections probably caused by P.
