Wild animals have been maintained in close association with humans since the dawn of human creation. Tremendous advances have been made in the care and management of wild animals, but some areas still need improvement. It is therefore important to identify the husbandry factors which minimize or maximize the occurrence of infectious or parasitic diseases. A universal influence on all animals is...
During an immune response a small number of rare Ag-specific clones proliferate extensively and decline, leaving a residual population for long-term memory. TCR transgenic (tg) CD4 T cells have been used widely to study the primary and memory response in vivo. We show here that naive TCR tg CD4 T cells from the DO11.10 strain transferred into wild type (wt) BALB/c recipients and not stimulated ...
Background and purpose: Heavy metals can enter into animals’ body through consumption of contaminated food and water and leave toxic effects on different organs. Considering the potential public health risk posed by heavy metal contamination, information about concentration of heavy metals in animals can help in analyzing the suitability of ecosystems. Materials and methods: This study...
Abstract Connecting people with nature is a powerful concept that opens doors for relationship building and conservation messaging. The roles of wild animals in the city (e.g., zoos aquariums) how we interact them—and vice versa—must evolve along our theoretical discussions animal management practices order to advance field. While taking into consideration long history captivity, where are toda...
two isolates of trichinella were obtained from the jackal, canis aureus: one from the north caspian area, the other from the south-west khuzestan area of iran. the infectivity of the isolates was tested in laboratory animals, in a wild rodent (tatera indica) and in wild pigs. the isolate from khuzestan was of low infectivity to albino rats and it was provisionally identified as trichinella nels...
Forty-one wild sheep (Ovis ammon orintalis) from Kabodan Island of National Park of Urmia Lake (North-West of Iran), were examined during a period of six months from October 2002 to March 2003, for helminthes and coccidian infection. The numbers of oocyst and eggs per gram of faeces (OPG & EPG) were determined by the centrifuge flotation technique using saturated sugar solution. The rate of inf...
Background and purpose: Wild boars (Sus scrofa) are potential reservoirs for a lot of zoonotic diseases, so it is possible to transmit these infections to wild and domestic animals and also humans. This research aimed to survey the protozoan prevalence of Sus scrofa in Mazandaran Province, North of Iran. Materials and methods: In a descriptive cross-sectional study a total of 21 wild boars was...
