mtdna indicates profound population structure in indian tiger panthera tigris tigris
Conservation Genetics, 2009Co-Authors: Reeta Sharma, Heiko Stuckas, Ranjana Bhaskar, Sandeep K Rajput, Surendra Prakash Goyal, Imran Khan, Ralph TiedemannAbstract:We analyzed mtDNA polymorphisms (parts of control region, ND5, ND2, Cytb, 12S, together 902 bp) in 59 scat and 18 tissue samples from 13 Indian populations of the critically endangered Indian tiger (Panthera tigris tigris), along with Zoo Animals as reference. Northern tiger populations exhibit two unique haplotypes suggesting genetic isolation. Western populations from Sariska (extinct in 2004) and Ranthambore are genetically similar, such that Ranthambore could serve as a source for reintroduction in Sariska. Zoo populations maintain mitochondrial lineages that are rare or absent in the wild.

genetic diversity of blastocystis in livestock and Zoo Animals
Protist, 2013Co-Authors: Mohammed A Alfellani, Hisao Yoshikawa, Rune C Stensvold, Derya Tanermulla, Alison S Jacob, Christine Atim Imeede, Graham C ClarkAbstract:Blastocystis is a common unicellular anaerobic eukaryote that inhabits the large intestine of many Animals worldwide, including humans. The finding of Blastocystis in faeces in mammals and birds has led to proposals of Zoonotic potential and that these hosts may be the source of many human infections. Blastocystis is, however, a genetically diverse complex of many distinct organisms (termed subtypes; STs), and sampling to date has been limited, both geographically and in the range of hosts studied. In order to expand our understanding of host specificity of Blastocystis STs, 557 samples were examined from various non-primate animal hosts and from a variety of different countries in Africa, Asia and Europe. STs were identified using 'barcoding' of the small subunit rRNA gene using DNA extracted either from culture or directly from faeces. The host and geographic range of several STs has thereby been greatly expanded and the evidence suggests that livestock is not a major contributor to human infection. Two new STs were detected among the barcode sequences obtained; for these, and for three others where the data were incomplete, the corresponding genes were fully sequenced and phylogenetic analysis was undertaken.

subtype distribution of blastocystis isolates from synanthropic and Zoo Animals and identification of a new subtype
International Journal for Parasitology, 2009Co-Authors: Rune C Stensvold, Mohammed A Alfellani, Sara Norskovlauritsen, Katrine Prip, Emma L Victory, Charlotte Maddox, Henrik Vedel Nielsen, Graham C ClarkAbstract:Blastocystis isolates from 56 Danish synanthropic and Zoo Animals, 62 primates primarily from United Kingdom (UK) collections and 16 UK primate handlers were subtyped by PCR, sequencing and phylogenetic analysis. A new subtype (ST) from primates and artiodactyls was identified and designated as Blastocystis sp. ST10. STs isolated from non-human primates (n=70) included ST3 (33%), ST8 (21%), ST2 (16%), ST5 (13%), ST1 (10%), ST4 (4%) and ST10 (3%). A high prevalence of ST8 was seen among primate handlers (25%). This ST is normally very rare in humans, suggesting that acquisition of Blastocystis ST8 infections from primates by their handlers had occurred in these cases. Data from published studies of non-human primates, other mammals and birds were collected and interpreted to generate a comprehensive overview on the ST distribution in such Animals. On the basis of information on 438 samples, it was found that Blastocystis from primates belong mainly to ST1, ST2, ST3, ST5 and ST8, ungulates and dogs mainly ST1, ST2, ST3, ST5 and ST10, rodents ST4 and birds mainly ST6 and ST7. The data indicate moderate host specificity, most clearly exemplified by the fact that STs isolated from avian and non-avian hosts rarely overlap.

calodium hepaticum syn capillaria hepatica in captive rodents in a Zoological garden
Journal of Comparative Pathology, 2005Co-Authors: Sharon P Redrobe, J C PattersonkaneAbstract:Calodium hepaticum infection was diagnosed in the Bristol Zoo Gardens in 13 captive rodents of four species that died or were humanely killed over a 40-month period. Of these infected Animals, nine were black-tailed prairie dogs (Cynomus ludovicianus), representing 45% of the members of this species examined during the study. A wild rat (Rattus norvegicus) found dead in an enclosure was also infected. To date few cases of C. hepaticum infection have been reported in the UK. The number of cases diagnosed in this urban Zoo may be explained by the potentially high prevalence of infection in urban rat populations and increased risk of exposure of Zoo Animals kept in enclosures to which rats have access. As C. hepaticum is potentially Zoonotic, members of staff in Zoos should be careful to avoid soil-to-mouth contact, particularly in prairie dog enclosures.

seroprevalences of antibodies to neospora caninum and toxoplasma gondii in Zoo Animals
Veterinary Parasitology, 2006Co-Authors: K Sedlak, E BartovaAbstract:Abstract Neospora caninum is an apicomplexan parasite that causes neuromuscular disease in dogs and abortions in cattle. Little is known about the prevalence of antibodies to this parasite in Zoo Animals. Sera from 556 Animals, from 13 Czech and Slovak Zoos were tested for antibodies to N. caninum and Toxoplasma gondii by indirect fluorescent antibody test. Antibodies to N. caninum were found in 31 of 556 Zoo Animals (5.6%), representing 18 of 114 species tested: Eurasian wolf ( Canis lupus lupus ), Maned wolf ( Chrysocyon brachyurus ), fennec ( Vulpes zerda ), cheetah ( Acinonyx jubatus ), jaguarundi ( Herpailurus yaguarondi ), Eurasian lynx ( Lynx lynx ), Indian lion ( Panthera leo goojratensis ), fisher ( Martes pennanti ), blackbuck ( Antilope cervicapra ), European bison ( Bison bonasus ), lechwe ( Kobus leche ), African buffalo ( Syncerus caffer caffer ), eland ( Taurotragus oryx ), sitatunga ( Tragelaphus spekei gratus ), Thorold's deer ( Cervus albirostris ), Eastern elk ( C. elaphus canadensis ), Vietnam sika deer ( C. nippon pseudaxis ) and Pere David's deer ( Elaphurus davidianus ). Titres ranged from 1:40 to 1:2560. The highest prevalence 50% was found in family mustelidae of the order carnivora. Antibodies to T. gondii were detected in 193 of 556 Zoo Animals (34.7%) representing 72 of 114 species tested, with titres ranging from 1:40 to 1:40960. The highest prevalence 100% was found in families: hyaenidae, mustelidae, ursidae and viveridae of the order carnivora. The results of this study indicate that Zoo Animals have more exposure to T. gondii than to N. caninum . It is the first report of seroprevalence of antibodies to N. caninum in European Zoo Animals.
