Glasnost and the great gerbil: Virulence polymorphisms in the epidemiology of leishmaniasis

Trends in Ecology & Evolution, 1990
botomus papatasi, particularly in spring and summer when trans- mission intensity is highs; and viru- lent clones outcompete avirulent ones when this vector is experimen- tally infected with bothg. The relative abundance of virulent and avirulent isolates from gerbils changes dramatically with season.

Molecular analysis of isolates of the cestode Rodentolepis nana from the great gerbil, Rhombomys opimus

Journal of Helminthology, 2015
AbstractRodentolepis nana (syn. Hymenolepis nana) is a cyclophyllidean zoonotic enteric parasite with worldwide distribution. In humans, it is more prevalent in children, especially in temperate zones. A morphologically similar species of R. nana occurs in different rodents, including gerbils.

Alarm signals of the great gerbil: acoustic variation by predator context, sex, age, individual, and family group.

The Journal of the Acoustical Society of America, 2005
The great gerbil, Rhombomys opinus, is a highly social rodent that usually lives in family groups consisting of related females, their offspring, and an adult male. The gerbils emit alarm vocalizations in the presence of diverse predators with different hunting tactics. Alarm calls were recorded in response to three predators, a monitor lizard, hunting

Prediction of the potential distribution pattern of the great gerbil (Rhombomys opimus) under climate change based on ensemble modelling.

Pest Management Science, 2022
BACKGROUND Rodent infestation is a global biological problem. Rodents are widely distributed worldwide, cause harm to agriculture, forestry, and animal husbandry production and spread a variety of natural focal diseases.

Survey for Rickettsiae Within Fleas of Great Gerbils, Almaty Oblast, Kazakhstan

Vector-Borne and Zoonotic Diseases, 2017
Little is known of the endemicity of flea-borne rickettsiae in Kazakhstan. Thus, a survey for rickettsiae within great gerbil fleas was conducted in Almaty oblast. High prevalence of Rickettsia asembonensis was detected among Xenopsylla gerbilli, demonstrating that flea-borne rickettsiae are endemic to southeastern Kazakhstan.

Bayesian Population Dynamics of Interacting Species: Great Gerbils and Fleas in Kazakhstan

Biometrics, 2005
SummaryWe propose a discrete‐time Bayesian hierarchical model for the population dynamics of the great gerbil–flea ecological system. The model accounts for the sampling variability arising from data originally collected for other purposes. The prior for the unknown population densities incorporates specific biological hypotheses regarding the ...

[Fertility of the flea, Xenopsylla gerbilli Minax, that parasitizes the great gerbil (Aphaniptera)].

Parazitologiia, 1979
It has been established experimentally that the fecundity of females of Xenopsylla gerbilli minax is wavy in its character from the beginning to end of their reproduction (peaks are replaced by falls). In spring and summer the egg laying proceeds on the 2nd--3rd day after the first bloodsucking of fleas and lasts to the end of their life. In autumn the

Persistence of plague outbreaks among great gerbils in Kazakhstan: effects of host population dynamics

Population Ecology, 2015
Abstract Outbreaks of plague ( Yersinia pestis ) among great gerbils ( Rhombomys opimus ) generally require a high host abundance to be initiated.

Transplacental (passive) transmission of plague antibodies in the great gerbil. Serological investigations in plague

Bulletin of Experimental Biology and Medicine, 1964
Passive transmission of plague antibodies from immune female great gerbils to their progeny was established. A high antibody titre was revealed in all the embryos, the placenta and amniotic fluid. The antibodies were retained in the serum of the young up to the 20th day after birth (observation period).
