It is important for animals to adapt to changes in food availability in order to survive. Hoarding is one method ofaccomplishing this and the golden hamster (Mesocricetus auratus) is particularly adept at hoarding. Previous literature suggests a connection between hoarding and stress. To further examine this connection, the present study looked at the effects of illumination and food deprivatio...

Barros and Austin (1) have reported on the inhibition of ovulation in the golden hamster by parenteral actinomycin D (AMD). During studies aimed at characterising the meiotic chromosome damage induced by various inhibitors of DNA, RNA, and protein, the author has made some observations in vitro and in vivo on the effects of AMD on female mouse meiosis . These data extend the information of Barr...

We compared transmission characteristics for prions from L-type bovine spongiform encephalopathy and MM2-cortical sporadic Creutzfeldt-Jakob disease in the Syrian golden hamster and an ovine prion protein-transgenic mouse line and isolated distinct prion strains. Our findings suggest the absence of a causal relationship between these diseases, but further investigation is warranted.

The objective of this study was to investigate fungal flora of the hair coat of domestic golden hamsterswith and without skin lesions. Sixty hamsters were examined in the Small Animal Teaching Hospitalof the Faculty of Veterinary Medicine, Ferdowsi University of Mashhad, and Mashhad, Iran. Asteriletoothbrush was used for sample collection, from the entire body of the hamsters, all skin lesions ...

background: irradiation is one of the major causes of induced sperm dna damage. various studies suggested a relation between sperm dna damage and fertilization rate after intra-cytoplasmic sperm injection (icsi). objective: in this study, fertilization rate and premature chromosome condensation (pcc) formation after icsi of hamster oocytes with irradiated sperms from normal and oligosperm indiv...

We qualitatively and quantitatively investigated the parathyroid glands of golden hamsters aged 6, 12, 18, 24 and 30 months. Percent area of rER in the parathyroid gland in golden hamsters at 24 months of age was significantly higher when compared to 6 and 12 months of age, and the percent area at 30 months of age was significantly higher when compared to 12 months of age, but there were no sig...

1. Balance studies were carried out with rats and golden hamsters (Mesocricetus auratus) given diets high and low in calcium (10.8 and 5.1-5.2 g Ca/kg respectively) and high and low in phytate (3.4 and 1.6 g phytate-phosphorus/kg respectively) in a 2 X 2 factorial experiment. 2. Values for Ca absorption and phytate availability (relative to the amount ingested) and for urinary excretion of Ca a...

Marburg virus (MARV), a close relative of Ebola virus, is the causative agent of a severe human disease known as Marburg hemorrhagic fever (MHF). No licensed vaccine or therapeutic exists to treat MHF, and MARV is therefore classified as a Tier 1 select agent and a category A bioterrorism agent. In order to develop countermeasures against this severe disease, animal models that accurately recap...
