ABSTRACT: The Mongolian gerbil (Meriones unguiculatus) serves as an animal model for a wide range of diseases. A practical limitation in its use is the definition of the hygienic status, as not much is known about viruses that potentially infect gerbils and might be transmitted to other rodents. As successful re-derivation was recently described for gerbils, we now aimed at investigating which mouse viruses induce seroconversion in gerbils and might be transmitted to mice. Gerbils were inoculated with viral agents of mice and co-housed with mouse contact sentinels. Seroconversion in gerbils was observed after oronasal inoculation with Sendai virus (SeV), mammalian orthoreovirus serotype 3 (Reo-3) and rotavirus A (RV-A, EDIM), seroconversion to RV-A also in sentinel mice. Pneumonia virus of mice (PVM) was not detected by serology but by polymerase chain reaction in gerbils and respective sentinel mice. No seroconversion towards or transmission of murine hepatitis virus, murine norovirus, minute virus of mice or mouse cytomegalovirus was detected. Anti-gerbil IgG antibodies did not increase sensitivity of indirect immunofluorescence (IFA) compared with anti-mouse IgG. In conclusion, seroconversion to SeV, Reo-3 and RV-A as well as transmission of RV-A and PVM indicate that these agents should be included in health monitoring of gerbils. Furthermore, anti-mouse IgG is suitable as a secondary antibody for IFA with gerbil serum.
