The genus Klebsiella belongs to the tribe Klebsiellae, a member of the family Enterobacteriaceae. The organisms are named after Edwin Klebs, a 19th century German microbiologist. Klebsiellae are nonmotile, rod-shaped, gram-negative bacteria with a prominent polysaccharide capsule. This capsule encases the entire cell surface, accounts for the large appearance of the organism on gram stain, and provides resistance against many host defense mechanisms.
Attempts by the Food and Drug Administration (FDA) to decrease the widespread use of antibiotics in livestock production have seldom succeeded. An effort to prohibit cephalosporins like Cefzil and Keflex in 2008 was stopped by frenzied lobbyists from the egg, chicken, turkey, milk, pork and cattle industries, who claimed they could not “farm” without the drugs.
A total of 679 strains of Klebsiella pneumoniae were selected for the study from June 2012-December 2013.@ http://www.omicsonline.org/open-access/prevalence-and-characterization-of-extended-spectrum-betalactamase-production-in-clinical-isolates-of-klebsiella-pneumonia-2161-0703-1000182.php?aid=53222
