Bacterial culture from gastrointestinal tract, oral cavity, and lesions such as abscesses. Histology with presence of abscesses with small gram-positive rods is indicative.
It is usually asymptomatic. Acute outbreaks of pyogenic infections with bacteraemia and lesions are abscesses in lungs, liver, kidneys, skin, synovium/arthritis.
Susceptible mouse strains: BALB/c nude, A/J, CBA/N, MPS, and BALB/cCr. Most resistant strains were C57Bl/6Cr, B10.BR/SgSn, ddY and ICR.
Asymptomatic, acute or chronic infections.
C.kutscheri is susceptible to most disinfectants used in animal facilities.
Pyogenic infections will result in significant disease and losses.
Pathogen exclusion by rederivation through caesarean section or embryo transfer onto/into pathogen free dams is recommended.
