Oxygen consumption, thermal conductance and body temperature of Meriones unguiculatus (Milne-Edwards, 1867) were measured at a temperature range from 5 to 40°C. The lowest mean metabolic rate tBMR) was 2.13 ± 0.14 ml02 g~ 1 h , which is higher than the predicted values based on their body mass. The thermal neutral zone (TNZ) was 26 to 38°C. Mean body temperature below the TNZ was 38.4 ± 0.5°C. Mean thermal conductance below the TNZ was 0.179 ± 0.037 ml02 g-1 • h-1 • °C which is also higher than predicted values based on their body mass. Thermoregulatory characteristics of Mongolian gerbils are very different from that found in arid-adapted small mammals. The extreme severe climate perhaps is the main selective force faced by Mongolian gerbils during their evolution with their macroenvironments.

A nematode Dentostomella translucida was found during parasitological examination of a pet Mongolian gerbil Meriones unguiculatus. Gerbils in the wild are known as hosts of this parasite in Asia, pet gerbils — in the USA and Brazil. Our record is the first in Europe. Complete descriptions of male and female individuals are given.

Using stained acryl latex injected techniques the arteries of the base of the brain in the Mongolian gerbil (Meriones unguiculatus) were studied. The brain of the Mongolian gerbil is supplied with blood by even internal carotid arteries and odd basilar artery. The branches of the internal carotid arteries supply the forebrain and interbrain. They form the arterial circle at the base of the brain. The basilar artery is a source of blood for the midbrain and hindbrain. In this species, except one case, the opened type at the back side of arterial circle was found. The posterior communicating arteries between basilar artery and internal carotid arteries were not observed.

Preliminary study of memory processes in Mongolian gerbil (Meriones unguiculatus). Mongolian gerbil (Meriones unguiculatus) a small rodent living in the wild steppes of Mongolia was discovered in 1866 and it is becoming increasingly popular as a pet. The present work is an introduction to describe the behavior of this species and to investigate the influence of gender and age on memory process. 40 gerbils divided into four study groups (young males, young females, adult males, adult females) were twice tested in a modified version of the Lashley III maze (repeat after a week). Using statistical tests memory parameters, the activity of animals and behavior associated with the level of stress were analyzed. Conducted observations and calculations performed showed no difference between the groups (p > 0.05), which leads to the conclusion that in Mongolian gerbils age and sex have no effect on memory.

Wstępne badanie procesów pamięciowych u myszoskoczka mongolskiego (Meriones unguiculatus).Myszoskoczek mongolski (Meriones unguiculatus) to mały gryzoń dziko żyjący na stepach Mongolii, odkryty w 1866 roku i stający się coraz bardziej popularny jako zwierzę domowe. Niniejsza praca stanowi wprowadzenie do opisania zachowania tego gatunku oraz zbadanie wpływu płci i wieku na procesy pamięci. 40 myszoskoczków podzielonych na cztery badane grupy (młode samce, młode samice, dorosłe samce, dorosłe samice) zostało dwukrotnie zbadanych zmodyfikowaną wersją labiryntu Lashley'a III (powtórzenie po tygodniu). Za pomocą testów statystycznych analizowano procesy pamięciowe, aktywność zwierząt oraz zachowania związane z poziomem stresu. Przeprowadzone analizy nie wykazały różnic między grupami (p > 0.05), co prowadzi do wniosku, że u myszoskoczków mongolskich wiek i płeć nie mają wpływu na procesy pamięciowe.

The impact of in vitro isolation and molecular characterisation of Neospora caninum as well as sequence analyses was studied. The brain homogenate of a naturally Neospora-infected dairy cow (positive in ELISA and Western blot) was intraperitoneally inoculated into Mongolian gerbils (Meriones unguiculatus). The brain of gerbils on day 60 post-inoculation was homogenized, and, after trypsin-digestion, cultured on Vero cells. Neospora-like tachyzoites were first observed after 77 days of cultivation. The parasite was confirmed by polymerase chain reaction (PCR) using Neospora-specific primers Np21 and Np6. The PCR product of the first Slovak isolate (NC-SKB1) was subsequently sequenced and published in GenBank under accession number GU300774. Sequencing and BLAST search identified the isolate as N. caninum.
