The adjustment of Calomys callosus (Rodentia, Cricetidae) to food deprivation [PDF]
The adjustment of Calomys callosus (Rodentia, Cricetidae) to intermittent food deprivation was investigated. Animals subjected either to 24-hr or to 48-hr repeated periods of deprivation successfully compensated, showing (1) increases in post-fast intake relatively to the intake by control animals; (2) rapid recovery of the baseline levels of body ...

Animal Models for the Study of Rodent‐Borne Hemorrhagic Fever Viruses: Arenaviruses and Hantaviruses
Human pathogenic hantaviruses and arenaviruses are maintained in nature by persistent infection of rodent carrier populations. Several members of these virus groups can cause significant disease in humans that is generically termed viral hemorrhagic fever (HF) and is characterized as a febrile illness with an increased propensity to cause acute ...

Trypanosoma cruzi infection was studied in mouse lines selected for maximal (AIRmax) or minimal (AIRmin) acute inflammatory reaction and for high (HIII) or low (LIII) antibody (Ab) responses to complex antigens. Resistance was associated with gender (females) and strain—the high responder lines AIRmax and HIII were resistant.
