A two-year study was carried out between February 2011 and January, 2013 to isolate and characterize
Salmonella from cases of suspected fowl typhoid and Pullorum disease in chickens in Kaduna,
Nigeria. Morganella morganii was isolated in pure culture from many of the fatal cases suspected to be
fowl typhoid or Pullorum disease. Morganella morganii, a Gram-negative rod commonly found in the
intestines of humans and other animals, was isolated in fatal infections in chickens by culture,
isolation and biochemical characterization using conventional means and commercial kits (Microbact®
GNB 24E and api®NH). Biochemical tests revealed that the isolates were positive for: catalase, nitrate,
citrate, urease, methyl red, and indole; and negative for oxidase and Voges Proskauer; they were
fermenters on Oxidative-fermentative test. Some important pathologic lesions noticed in birds at post
mortem included: enlarged and congested spleen, enlarged congested and friable liver with areas of
necrosis, congested lungs; congested, mis-shapened and regressed ovaries. Experimental infection of
chickens with the organism is hereby recommended. There is also the need for further characterization
of isolates to determine the strains and antibiotic resistance genes.
