Moreover, one should suspect these strains when treatment with these agents for gram-negative infections fails despite reported in vitro susceptibility. Once an ESBL-producing strain is detected, the laboratory should report it as "resistant" to all penicillins, cephalosporins, and aztreonam, even if it is tested (in vitro) as susceptible.
Proteus mirabilis is a Gram-negative, facultatively anaerobic, rod-shaped bacterium. It shows swarming motility and urease activity. P. mirabilis causes 90% of all Proteus infections in humans. It is widely distributed in soil and water. [1] Proteus mirabilis can migrate across the surface of solid media or devices using a type of cooperative ...
Escherichia coli O157:H7 is a serotype of the bacterial species Escherichia coli and is one of the Shiga-like toxin–producing types of E. coli. It is a cause of disease, typically foodborne illness, through consumption of contaminated and raw food, including raw milk and undercooked ground beef. [1][2] Infection with this type of pathogenic ...
β-Lactam antibiotics (beta-lactam antibiotics) are antibiotics that contain a β-lactam ring in their chemical structure. This includes penicillin derivatives (penams), cephalosporins and cephamycins (cephems), monobactams, carbapenems [1] and carbacephems. [2] Most β-lactam antibiotics work by inhibiting cell wall biosynthesis in the ...
