A FATAL MIXED BACTERIAL INFECTION IN GUINEA PIGS – CLINICAL SYMPTOMS, MICROBIOLOGY AND PATHOMORPHOLOGY – CASE REPORT

The paper describes a case of an acute lethal infection in guinea pigs, demonstrated with watery to bloody profuse diarrhea, respiratory paralysis and death. Microbiological tests indentified several isolates: Clostridium novyi (oedematiens) (C. novyi), Escherichia coli (E. coli), Enterococcus sp. and Bacillus cereus (B. cereus). Materials from internal organs were obtained for pathohistological examination. Histo-ry data, microbiology and histopathology were evidential for toxin-forming pathogenic microorganisms, imported by food and/or probably turned to virulent endogenous bacterial strains, causing the death of the animals.
