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.

A CONTRIBUTION TO THE PATHOLOGICAL ANATOMY OF PLAGUE IN GREAT GERBILS UNDER NATURAL CONDITIONS

, 1966
Abstract : The pathologoanatomical picture was studied in 182 naturally infected great gerbils. Of these, in 12% a generalized form of plague with the presence of septicemia was recorded, and in 88% a local form of infection was noted. In the latter the plague microbe was isolated only from the liver in 9%, only from the spleen in 44%, simultaneously ...

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

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 ...

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.

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

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).

A computer model of plague epizootic process in the great gerbil (Rhombomys opimus) settlements: Description and test for adequacy

Biology Bulletin, 2010
The spread of plague epizootics in areas with natural plague foci, including Rhombomys opimus settlements, is usually studied in the course of annual epizootiological observations. Direct studies on the structure of epizootics and parameters of their spread are labor-intensive and, therefore, rare.

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

Population Ecology, 2015
AbstractOutbreaks of plague (Yersinia pestis) among great gerbils (Rhombomys opimus) generally require a high host abundance to be initiated. The duration of an outbreak is expected to depend on the subsequent development of this abundance; however, prediction is nontrivial due to the complexity of the gerbil–plague system. The aim of this study was to

Mitochondrial DNA diversity in the populations of great gerbils, Rhombomys opimus, the main reservoir of cutaneous leishmaniasis

Acta Tropica, 2011
Accurate identification of animal reservoirs of transmissible diseases is an absolute requirement to any epidemiological survey of zoonoses and is essential for predicting species-specific population outbreaks and therefore to develop accurate ecological control strategies.

OBSERVATIONS ON THE ROLE OF THE REACTIVITY OF GREAT GERBILS TO P. PESTIS DURING THE DEVELOPMENT OF THE EPIZOOTOLOGICAL PROCESS. 2. DYNAMICS OF THE HEMAGGLUTININS IN THE GREAT GERBILS AFTER A PRIMARY CONTACT WITH P. PESTIS. (ALMA-ATA; TALDY-KURGAN)

1966
Abstract : The report is devoted to revealing the regularities in the dynamics of hemagglutinins in great gerbils -- the main carriers of the plague microbe in the Central Asian desert plague focus -- after their initial contact with the causative agent.
