In the urine of plague-infected great gerbils Yersinia pestis capsular antigen was detected by means of diagnostic preparations, both commercial and experimental (based on monoclonal antibodies). The antigen was detected in many urine samples taken from the animals over a prolonged period. The incidence and duration of antigenuria were found to be related to the survival time of great gerbils after infection and the level of antibodies in their blood. The number of animals with antigenuria markedly exceeded the number of animals from which Y. pestis was isolated, especially at a later period after infection. Examinations of urine samples from live great gerbils trapped in natural foci appears to be a method more effective in epizootiological survey than the bacteriological analysis of the animals.

The great gerbil () is a gregarious rodent in Central Asia and is one of the major pests found in desert forest and grassland areas. The distribution changes and migration routes of in Central Asia under climate change remain unexplored. This study employed multi-model ensemble, correlation analysis, jackknife method, and minimum cumulative resistance (MCR) model to simulate the potential habitat of under current and future (2030 and 2050) climate scenarios and estimate its possible migration routes.

Rodents, such as those that feed on plants and nest in plant roots, can significantly affect the growth and development of desert plants. The aim of this study was to investigate the effects of disturbance on the photosynthetic characteristics and nutrient status of at different growth stages in the Gurbantunggut Desert. The effects of great gerbil disturbance on the photosynthetic characteristics of at different growth stages were investigated by measuring the gas exchange parameters, instantaneous water use efficiency, and chlorophyll fluorescence parameters of at different ages (young, middle, and adult) under the disturbance of great gerbils.

Background And Aim: Echinococcosis is one of the most dangerous parasitic diseases common to humans and animals. In Kazakhstan, echinococcosis is widespread in animals. This study aimed to estimate the prevalence and biological characteristics of echinococcosis in agricultural animals, dogs, wild carnivores, and rodents in the Western region of the Republic of Kazakhstan.

Studying parasitic nematodes, which generate a massive hazard to animal health, is more difficult than studying free-living nematodes as appropriate animal models are essential, and the relationship between parasites and hosts is extremely complex. is an intestinal nematode parasite that mainly infects dogs, humans and other primates. Currently, worms needed for research mainly rely on their natural host, the dog.
