First Report Of Canine Visceral Leishmaniasis In Bulgaria, Ilia Tsachev, Ioannis D. Kyriazis, Sofia Boutsini, Evdokia Karagouni, Eleni Dotsika Jan 2010

First Report Of Canine Visceral Leishmaniasis In Bulgaria, Ilia Tsachev, Ioannis D. Kyriazis, Sofia Boutsini, Evdokia Karagouni, Eleni Dotsika

Turkish Journal of Veterinary & Animal Sciences

Seroepidemiological studies on canine leishmaniasis in Bulgaria, even in areas where human leishmaniasis has been detected, are controversial. This report describes 2 clinical cases of canine visceral leishmaniasis. The disease was confirmed by microscopical, serological, and molecular methods. It is, therefore, suggested that infected dogs could constitute the reservoir for human leishmaniasis in the country.

Intestinal Geotrichosis In A German Shepherd, Yajane Lee, Wei-Li Hsu, Chin-Fu Lin, Shao-Wei Lee, Feng-Pang Cheng

Turkish Journal of Veterinary & Animal Sciences

A 4-year-old sexually intact male German shepherd with a 3-month history of chronic watery diarrhea was referred to the Veterinary Medical Teaching Hospital. Dehydration and serum biochemistry revealed hypoalbuminemia, and fecal material contained a large quantity of round arthroconidia that were microscopically observed. A specimen was submitted for fungal culture and yielded a white to cream-colored subsurface colony. Microorganisms derived from the colony exhibited chains of smooth, septate hyaline hyphae that were producing 1-celled arthroconidia. Geotrichum candidum was thus identified. Colonoscopic features included erythema, edema, and loss of the usual fine vascular pattern, with granularity of the mucosa of the …

Estimating The Extent Of Spatial Association Of Mycobacterium Bovis Infection In Badgers In Ireland, G. E. Kelly, G. E. Mcgrath, S. J. More Jan 2010

Estimating The Extent Of Spatial Association Of Mycobacterium Bovis Infection In Badgers In Ireland, G. E. Kelly, G. E. Mcgrath, S. J. More

Michigan Bovine Tuberculosis Bibliography and Database

Mycobacterium bovis infects the wildlife species badgers Meles meles who are linked with the spread of the associated disease tuberculosis (TB) in cattle. Control of livestock infections depends in part on the spatial and social structure of the wildlife host. Here we describe spatial association of M. bovis infection in a badger population using data from the first year of the Four Area Project in Ireland. Using second-order intensity functions, we show there is strong evidence of clustering of TB cases in each the four areas, i.e. a global tendency for infected cases to occur near other infected cases. Using …

Emergence Of Diseases From Wildlife Reservoirs, J. C. Rhyan, T. R. Spraker Jan 2010

Emergence Of Diseases From Wildlife Reservoirs, J. C. Rhyan, T. R. Spraker

Michigan Bovine Tuberculosis Bibliography and Database

Interest in the epidemiology of emerging diseases of humans and livestock as they relate to wildlife has increased greatly over the past several decades. Many factors, most anthropogenic, have facilitated the emergence of diseases from wildlife. Some livestock diseases have ‘‘spilled over’’ to wildlife and then ‘‘spilled back’’ to livestock. When a population is exposed to an infectious agent, depending on an interaction of factors involving the host, agent, and environment, the population may be resistant to infection or may become a dead-end host, a spillover host, or a maintenance host. Each exposure is unique; the same species of host …

Comparative Studies On The Sensitivity Of Polymerase Chain Reaction (Pcr) And Microscopic Examination For The Detection Of Trypanosoma Evansi In Horses, M.A. Muieed, Zafar Iqbal Chaudhry, A. R. Shakoori Jan 2010

Comparative Studies On The Sensitivity Of Polymerase Chain Reaction (Pcr) And Microscopic Examination For The Detection Of Trypanosoma Evansi In Horses, M.A. Muieed, Zafar Iqbal Chaudhry, A. R. Shakoori

Turkish Journal of Veterinary & Animal Sciences

The lack of reliable diagnostic methods is a setback in the effective control of diseases. Diagnosis of Trypanosoma evansi infection (surra) in livestock is of considerable economic importance. Detection of trypanosomes in blood has been the "gold standard"; however, finding the organisms or establishing patency of parasitaemia has not always been possible even in symptomatic infections. As a consequence of low dose infection, the pre-patent period in Trypanosoma evansi may be longer and, even when symptoms have developed, trypanosomes may still not be demonstrable in blood, thus delaying treatment and thereby increasing morbidity and mortality. Trypanosoma evansi, a protozoan parasite …

The Role Of Bone Marrow In Siv Pathogenesis Using The Rhesus Macaque Model, Amy F. Gill Jan 2010

The Role Of Bone Marrow In Siv Pathogenesis Using The Rhesus Macaque Model, Amy F. Gill

LSU Doctoral Dissertations

CD4+ memory T cells are depleted in mucosal tissues post human immunodeficiency virus (HIV) and simian immunodeficiency virus (SIV) infection without restoration to pre-infection levels during progressive course of disease. Bone marrow (BM) as a hematopoietic organ has been investigated for hematologic and morphologic changes during HIV infection. However, BM as a primary lymphoid tissue during HIV infection has been poorly characterized. We proposed BM was also a site of CD4+ T cell depletion driven by increased apoptosis during progressive HIV disease. We chose to investigate bone marrow changes using the premier non-human primate Rhesus macaque SIV model for the …

Role Of Gastrointestinal Multidrug Resistance (Mdr1) Gene And P-Glycoprotein (P-Gp) In The Oral Absorption Of Methadone In Horses, Renata Lehn Linardi Jan 2010

Role Of Gastrointestinal Multidrug Resistance (Mdr1) Gene And P-Glycoprotein (P-Gp) In The Oral Absorption Of Methadone In Horses, Renata Lehn Linardi

LSU Doctoral Dissertations

Methadone is a mu-opioid receptor agonist which is a very effective analgesic used to treat moderate to severe acute and chronic pain in humans. Due to methadone’s minimal undesirable side-effects in people, we believed it could be of use in horses as an analgesic agent. As found with the majority of lipophilic drugs, absorption of methadone occurs primarily in the small intestine via transcellular transport and its absorption is regulated by P-glycoprotein. P-glycoprotein is a transmembrane transporter protein encoded by the multidrug resistance gene, which is constitutively expressed in the apical membrane of enterocytes of various species. This protein may …

In Vivo And In Vitro Pathogenesis Of Francisella Asiatica In Tilapia Nilotica (Oreochromis Niloticus), Esteban Soto Jan 2010

In Vivo And In Vitro Pathogenesis Of Francisella Asiatica In Tilapia Nilotica (Oreochromis Niloticus), Esteban Soto

LSU Doctoral Dissertations

Francisella asiatica is a Gram negative, facultative intracellular pathogen that causes fish francisellosis. In this project, homologues to the F. tularensis iglABCD genes were found present in F. asiatica. As few as 23 F. asiatica bacteria injected in the peritoneum were found capable of causing mortalities in tilapia nilotica (Oreochromis niloticus), and even fewer were enough to cause pathological changes. We examined the in vivo and in vitro interaction of F. asiatica wild type (WT) and a ÄiglC strain with tilapia and tilapia head kidney derived macrophages (HKDM). The ÄiglC was found to be attenuated following intraperitoneal and immersion challenges …

In Vitro And In Vivo Evaluation Of A Brucella Putative Hemagglutinin, Lauren E. Duhon Jan 2010

In Vitro And In Vivo Evaluation Of A Brucella Putative Hemagglutinin, Lauren E. Duhon

LSU Doctoral Dissertations

Brucellosis, a zoonotic disease caused by Brucella spp., presents both health and economic difficulties for livestock, wildlife, and humans. While brucellosis is nearly eradicated in the United States, the disease remains detrimental in many countries worldwide. Attempts to produce a safe and effective small ruminant vaccine have been met with limited success. The current vaccine for bovine brucellosis in the United States is B. abortus RB51. This strain transiently colonizes the host and induces a cell-mediated immune response. Levels of protection have not been demonstrated in goats and thus it is considered a relatively poor caprine vaccine that probably does …

Ospc In The Pathogenesis Of Borrelia Burgdorferi, Sunita V. Seemanapalli Jan 2010

Ospc In The Pathogenesis Of Borrelia Burgdorferi, Sunita V. Seemanapalli

LSU Doctoral Dissertations

Lyme disease is a multisystem disorder caused by the tick vector Borrelia burgdorferi. During its life cycle between the tick vector and the mammalian host, Borrelia up- and down-regulates the expression of its surface lipoproteins. Of its many surface lipoproteins, the Outer surface protein C (OspC) is crucial for initial mammalian infection. OspC has a common role shared with other lipoproteins of protection against host innate defences and a unique function in facilitating the dissemination of B. burgdorferi in the murine host. The structure of OspC was solved in 2001 and the lipoprotein was found to be predominantly alpha-helical with …

Conception Rates For Standing Estrus And Fixed-Time Insemination In Dairy Heifers Synchronized With Gnrh And Pgf_{2\Alpha}, Samir Z. El-Zarkouny Jan 2010

Conception Rates For Standing Estrus And Fixed-Time Insemination In Dairy Heifers Synchronized With Gnrh And Pgf_{2\Alpha}, Samir Z. El-Zarkouny

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to evaluate the effectiveness of GnRH PGF-based protocols on reproductive outcome in Holstein heifers. Heifers were randomly assigned to the control group (n = 14), or treatment groups (n = 50) treated with GnRH (day -7) and PGF_{2\alpha} (day 0). Heifers that exhibited estrus were inseminated (Select Synch, n = 34) and heifers that did not exhibit estrus up to 48 h after PGF_{2\alpha} injection received a second GnRH injection and were fixed-time inseminated (Ovsynch, n = 16). Conception rates were 40%, 55.9%, and 31.3%, and overall pregnancy rates (P < 0.05) were 64.3%, 97%, and 87.5% in the control, Select Synch, and Ovsynch groups, respectively. Ovsynch heifers had 1.8 ± 0.5 and 3.2 ± 0.6 ng mL^{–1} of serum P4, versus 3.3 ± 0.5 and 3.8 ± 0.6 ng mL–1 in the Select Synch heifers at the time of the first GnRH and PGF_{2\alpha} injection, respectively. Conception rates were 55.6% and 58.3% when P4 concentrations were high, and were 50% and 25% when P4 concentrations were low at the time of the first GnRH and PGF_{2\alpha} injection, respectively. Dairy heifers synchronized with GnRH and PGF_{2\alpha} should be inseminated when estrus is observed, and heifers that do not exhibit estrus up to 48 h after PGF_{2\alpha} injection should be given a second GnRH injection and fixed-time inseminated 16-20 h later.

Impairments In Haematological Parameters Of Saprolegnia Spp. Infected Tench,Tinca Tinca, Syed Lal Shah Jan 2010

Impairments In Haematological Parameters Of Saprolegnia Spp. Infected Tench,Tinca Tinca, Syed Lal Shah

Turkish Journal of Veterinary & Animal Sciences

Haematological parameters of tench (Tinca tinca) infected by Saprolegnia spp. were studied. All parameters, except mean corpuscular volume (MCV), decreased in response to infection. A significant (P < 0.05) decrease was observed in haemoglobin (Hb) (-26.85%), red blood cell count (RBCc) (-20.94%), leucocrit (Lct) (-24.14%), and mean corpuscular haemoglobin concentration (MCHC) (-9.06%). Haematocrit (Hct), white blood cell count (WBCc), and mean corpuscular haemoglobin (MCH) also decreased (-7.66%, -12.44%, and -6.19%, respectively); however, differences between the infected and control groups were not significant. Among the parameters, only MCV had a non-significant increase (+7.84%) in the infected fish. The study results show that saprolegniasis caused anaemia and immunosuppression, followed by mortality in tench. Mortality was attributed to haemodilution caused by haemorrhaging and the breakdown of osmotic balance due to tissue (skin and muscular layer) destruction via the penetration of the hyphae; however, lethargy was another mortality promoting factor. Mortality among the Saprolegnia-infected fish also depended upon the initial site of infection, type of tissue destroyed, growth rate of the fungus, and ability of individual fish to withstand the stress. The present study was conducted to investigate physiological impairment in Saprolegnia-infected Tinca tinca under laboratory conditions; however, further studies at the population level in natural habitats and under similar stress conditions are needed.
