Pseudorabies detected in hunting dogs in Alabama and Arkansas after close contact with feral swine (Sus scrofa).

Background: Pigs (Sus scrofa) are the natural hosts of pseudorabies virus (PRV), also known as Aujeszky's disease. Infection in mammals, with the exception of humans, typically causes extreme itching, facial swelling, and excessive salivation, followed by death in non-suid species. The risk to susceptible mammals was assumed to decrease when PRV was eliminated from U.

Diminished activity of ceftizoxime in comparison to cefotaxime and ceftriaxone against Streptococcus pneumoniae.

Previous reports documenting the essentially identical spectra of activity of ceftizoxime, cefotaxime, and ceftriaxone prompted our hospital formulary committee to replace the latter two drugs with ceftizoxime on the basis of cost differences. However, we subsequently observed that every one of 60 isolates of Streptococcus pneumoniae tested was less susceptible to ceftizoxime than to either cefotaxime or ceftriaxone. The difference between minimal inhibitory concentrations (MICs) was greatest for strains moderately or fully resistant to penicillin, which at our institution represent approximately 32% of all isolates of S.
