Non-typhoid Salmonella spp. resistant to cefotaxime

J Antimicrob Chemother. 1995 Oct;36(4):697-702. doi: 10.1093/jac/36.4.697.

Abstract

beta-Lactamases with pIs of 5.4 and 8.1 were detected by hydrolysis of ampicillin and ceftriaxone respectively among cefotaxime resistant serovars of Salmonella spp. suggesting TEM-1 and an unidentified extended spectrum beta-lactamase have spread throughout these strains in Argentina.
