Disseminated Streptococcus Equi Subsp. Zooepidemicus Infection In A Foal And Associated Mastitis In A Mare, A. Levent Kocabiyik, Esra Büyükcangaz, Ahmet Akkoç, Cüneyt Özakin, İ. Taci̇ Cangül

Turkish Journal of Veterinary & Animal Sciences

A systemic infection with Streptococcus equi subsp. zooepidemicus is described in a 22-day-old female foal for the first time in Turkey. Clinically the foal was in poor condition and had severe pneumonia. Painful swellings of the carpal and tarsal joints were evident. Examination of the dam revealed clinical mastitis. Postmortem histopathological and microbiological examinations of samples from the foal revealed a disseminated infection with S. equi subsp. zooepidemicus. The causative agent was also recovered in pure culture from a milk sample of the mare.


A Study Of Somatic Cell Counts In The Milk Of Holstein-Friesian Cows Managed In Mediterranean Climatic Conditions, Atakan Koç Jan 2008

A Study Of Somatic Cell Counts In The Milk Of Holstein-Friesian Cows Managed In Mediterranean Climatic Conditions, Atakan Koç

Turkish Journal of Veterinary & Animal Sciences

Somatic cell counts (SCC) in the milk of Holstein-Friesian (HF) cows were determined by direct microscopic SCC technique. For a two-year period, milk samples were collected monthly from buckets during the morning and evening milkings at 4 different dairy farms. In total, 1,464 SCC readings from 88 HF cows were analyzed by using repeated measures. Herd, lactation month, parity, milking time, and herd interaction effects on SCC were statistically significant (P < 0.05). The average SCC in milk per herd was between 296,483 and 688,811 cells/ml. SCC in milk increased as parity increased. The average SCC in milk from evening milking was about 83,165 cells/ml higher than from morning milking. Improving milking management, reducing stress, providing extra care during the first month of lactation, and milking at a uniform interval will help to decrease SCC in milk and the prevalence of mastitis.

Anticoagulant Rodenticide Intoxication In Animals – A Review, Ivan Valchev, Rumen Binev, Veska Yordanova, Yordan Nikolov Jan 2008

Anticoagulant Rodenticide Intoxication In Animals – A Review, Ivan Valchev, Rumen Binev, Veska Yordanova, Yordan Nikolov

Turkish Journal of Veterinary & Animal Sciences

The newest measures for the control of harmful rodent populations are from the anticoagulant rodenticide group, which are divided into 2 subgroups: first and second generations, and indandione derivatives. Non-target organisms are potentially at risk of direct consumption of baits (primary hazard) and of eating poisoned rodents (secondary hazard). Anticoagulant rodenticides inhibit the enzyme vitamin K-dependent carboxylase and thus impair the reactivation of vitamin K1, indirectly affecting physiological blood coagulation. The diagnosis is made on the basis of clinical signs (massive hemorrhages), laboratory findings, and especially the changes in coagulation markers (APTT, PT, TT, PCT, ACT, FDPs, and PIVKA). The …

Porcine Intestinal Epithelial Cell Lines As A New In Vitro Model For Studying Adherence And Pathogenesis Of Enterotoxigenic Escherichia Coli, Seung Y. Koh, Sajan George, Volker Brozel, Rodney A. Moxley, David H. Francis, Radhey Kaushik

School of Veterinary and Biomedical Sciences: Faculty Publications

Enterotoxigenic Escherichia coli (ETEC) infections result in large economic losses in the swine industry worldwide. The organism causes diarrhea by adhering to and colonizing enterocytes in the small intestines. While much progress has been made in understanding the pathogenesis of ETEC, no homologous intestinal epithelial cultures suitable for studying porcine ETEC pathogenesis have been described prior to this report. In the current study, we investigated the adherence of various porcine ETEC strains to two porcine (IPEC-1 and IPEC-J2) and one human (INT-407) small intestinal epithelial cell lines. Each cell line was assessed for its ability to support the adherence of …


Light-Evoked Calcium Responses Of Isolated Melanopsin- Expressing Retinal Ganglion Cells, Andrew T. E. Hartwick, Jayne R. Bramley, Jianing Yu, Kelly T. Stevens, Charles N. Allen, William H. Baldridge, Patricia J. Sollars, Gary E. Pickard Dec 2007

Light-Evoked Calcium Responses Of Isolated Melanopsin- Expressing Retinal Ganglion Cells, Andrew T. E. Hartwick, Jayne R. Bramley, Jianing Yu, Kelly T. Stevens, Charles N. Allen, William H. Baldridge, Patricia J. Sollars, Gary E. Pickard

School of Veterinary and Biomedical Sciences: Faculty Publications

A small number (<2%) of mammalian retinal ganglion cells express the photopigment melanopsin and are intrinsically photosensitive (ipRGCs). Light depolarizes ipRGCs and increases intracellular calcium levels ( [Ca2+]i ) but the signaling cascades underlying these responses have yet to be elucidated. To facilitate physiological studies on these rare photoreceptors, highly enriched ipRGC cultures from neonatal rats were generated using anti-melanopsin-mediated plate adhesion (immunopanning). This novel approach enabled experiments on isolated ipRGCs, eliminating the potential confounding influence of rod/cone-driven input. Light induced a rise in [Ca2+]i (monitored using fura-2 imaging) in the immunopanned ipRGCs and the source of this Ca2+ signal was investigated. The Ca2+ responses were inhibited by 2-aminoethoxydiphenyl borate, SKF-96365 (1–2-(4-methoxyphenyl)-2-[3-(4-methoxyphenyl)propoxy]ethyl-1H-imidazole), flufenamic acid, …


Stable Cell Lines Expressing High Levels Of The Herpes Simplex Virus Type 1 Lat Are Refractory To Caspase 3 Activation And Dna Laddering Following Cold Shock Induced Apoptosis, Dale Carpenter, Chinhui Hsiang, Donald J. Brown, Ling Jin, Nelson Osorio, Lbachir Benmohamed, Clinton J. Jones, Steven L. Wechsler Dec 2007

Stable Cell Lines Expressing High Levels Of The Herpes Simplex Virus Type 1 Lat Are Refractory To Caspase 3 Activation And Dna Laddering Following Cold Shock Induced Apoptosis, Dale Carpenter, Chinhui Hsiang, Donald J. Brown, Ling Jin, Nelson Osorio, Lbachir Benmohamed, Clinton J. Jones, Steven L. Wechsler

School of Veterinary and Biomedical Sciences: Faculty Publications

The herpes simplex virus type 1 (HSV-1) latency associated transcript (LAT) gene’s anti-apoptosis activity plays a central, but not fully elucidated, role in enhancing the virus’s reactivation phenotype. In transient transfection experiments, LAT increases cell survival following an apoptotic insult in the absence of other HSV-1 genes. However, the high background of untransfected cells has made it difficult to demonstrate that LAT inhibits specific apoptotic factors such as caspases. Here we report that, in mouse neuroblastoma cell lines (C1300) stably expressing high levels of LAT, cold shock induced apoptosis was blocked as judged by increased survival, protection against DNA fragmentation …


Neuroanatomy Of The Subadult And Fetal Brain Of The Atlantic White-Sided Dolphin (Lagenorhynchus Acutus) From In Situ Magnetic Resonance Images, Eric W. Montie, Gerald E. Schneider, Darlene R. Ketten, Lori Marino, Katie E. Touhey, Mark E. Hahn Dec 2007

Neuroanatomy Of The Subadult And Fetal Brain Of The Atlantic White-Sided Dolphin (Lagenorhynchus Acutus) From In Situ Magnetic Resonance Images, Eric W. Montie, Gerald E. Schneider, Darlene R. Ketten, Lori Marino, Katie E. Touhey, Mark E. Hahn

Veterinary Science and Medicine Collection

This article provides the first anatomically labeled, magnetic resonance imaging (MRI) -based atlas of the subadult and fetal Atlantic white-sided dolphin (Lagenorhynchus acutus) brain. It differs from previous MRI-based atlases of cetaceans in that it was created from images of fresh, postmortem brains in situ rather than extracted, formalin-fixed brains. The in situ images displayed the classic hallmarks of odontocete brains: fore-shortened orbital lobes and pronounced temporal width. Olfactory structures were absent and auditory regions (e.g., temporal lobes and inferior colliculi) were enlarged. In the subadult and fetal postmortem MRI scans, the hippocampus was identifiable, despite the relatively small size …

Microsattellite Polymorphism And Parentage Control In Thai Domestic Elephants (Elephas Maximus), Duangsmorn Suwattana, Weerapong Koykul, Jutharat Jirasupphachok, Sumolya Kanchanapangka

The Thai Journal of Veterinary Medicine

Polymorphism of microsatellite DNA in Thai domestic elephants (Elephas maximus) was studied using five genetic markers including LaT05, LaT07, LaT16, LaT17 and LaT26, in order to determine the efficiency of such markers in parentage identification. Eleven elephants from 5 families and 10 unrelated ones located in the northern, northeastern and central parts of Thailand were tested. It was found that LaT05, LaT16, LaT17 and LaT26 possessed marker sizes of 250-500 bp with numbers of alleles ranging from 4-13, heterozygosity 0.62-0.88 and PIC 0.56-0.87 whereas LaT07 could not be detected in all specimens used. LaT05 and LaT26 appeared to be the …

Potential Study Of Using Earthworms As An Enhancement To Treat High Strength Wastewater, Nathasith Chiarawatchai, Chackrit Nuengjamnong, Pichaya Rachdawong, Ralf Otterpohl Dec 2007

Potential Study Of Using Earthworms As An Enhancement To Treat High Strength Wastewater, Nathasith Chiarawatchai, Chackrit Nuengjamnong, Pichaya Rachdawong, Ralf Otterpohl

The Thai Journal of Veterinary Medicine

The aim of this research was to preliminarily investigate the potential of earthworms to reduce clogging by introducing into the lab-scale wetland-like reactors receiving high strength wastewater, which were swine wastewater in Thailand, and domestic wastewater in Germany. The preliminary results indicated that every unit with earthworms had no sign of clogging regardless of the type of wastewater, whereas clogging was the case in the units without earthworms receiving swine wastewater. Both studies reflected similarity, which exhibited little treatment in every microcosm. It could be implied that earthworms could thrive within the wetland body due to the survival rate of …

Molecular Diagnostic To Identify Mycobacterial Species In Veterinary Science, Carlos Julian De Luna, Olivier Andre Ettore Sparagano

The Thai Journal of Veterinary Medicine

The genus Mycobacterium is of utmost importance in veterinary medicine. Members of the genus cause serious diseases to livestock and they also could be transmitted to humans. Bovine tuberculosis, principally caused by M. bovis, is a widespread disease and causes serious economic losses to farmers worldwide. Paratuberculosis or Johne’s disease caused by the M. avium complex, is a slow-developing disease present in several species, particularly cattle, and it has been associated with Chrone’s disease of humans. It causes diarrhoea, and weight loss that could be fatal. The common diagnostic methods used rely upon culturing and microbiological identification of the Mycobacterium …

Review Of The Efficacy And Safety Of Poly (2-Propenal, 2-Propenoic Acid): A Novel Antimicrobial Polymer, Alistair Iain Murdoch, Rosalie Dianne Mccauley, David John Hampson Dec 2007

Review Of The Efficacy And Safety Of Poly (2-Propenal, 2-Propenoic Acid): A Novel Antimicrobial Polymer, Alistair Iain Murdoch, Rosalie Dianne Mccauley, David John Hampson

The Thai Journal of Veterinary Medicine

The withdrawal of antibiotic growth promoters is likely to increase the incidence of enteric disease in pig and broiler farms; especially in poorly sanitised conditions. Therefore, replacements for the antibiotic growth promoters currently used in both pig and poultry production, which offer disease control and delay the further development of antibiotic resistance, will become increasingly important. Poly (2-propenal, 2-propenoic acid) (pPPA) is a new chemical entity undergoing development by Chemeq Ltd, Australia. It was designed to contain aldehyde groups for antimicrobial activity, carboxylic acid groups to aid water solubility and conformationally is a long chain, high molecular weight polymer developed …

White coat color has been a highly valued trait in horses for at least 2,000 years. Dominant white (W) is one of several known depigmentation phenotypes in horses. It shows considerable phenotypic variation, ranging from approximately 50% depigmented areas up to a completely white coat. In the horse, the four depigmentation phenotypes roan, sabino, tobiano, and dominant white were independently mapped to a chromosomal region on ECA 3 harboring the KIT gene. KIT plays an important role in melanoblast survival during embryonic development. We determined the sequence and genomic organization of the approximately 82 kb equine KIT gene. A mutation …

2006 Michigan Dairy Farm Business Analysis Summary, Eric Wittenberg, Christopher Wolf

Michigan Bovine Tuberculosis Bibliography and Database

This report summarizes the financial and production records of 139 dairy farms from throughout Michigan in 2006. To be included, the farms must have produced at least 50 percent of gross cash farm income from milk and dairy animal sales. The records came from Michigan State University’s TelFarm project and the Farm Credit Service system in Michigan. The values were pooled into averages for reporting purposes. The farms are larger than would be the average of all dairy farms in Michigan. While considerable variation in the data exists, average values are reported in the summary tables and discussion that follows.


Differences In Virulence Among Escherichia Coli O157:H7 Strains Isolated From Humans During Disease Outbreaks And From Healthy Cattle, Diane R. Baker, Rodney A. Moxley, Mike B. Steele, Jeffrey T. Lejeune, Jane Christopher-Hennings, Ding-Geng Chen, Philip R. Hardwidge, David H. Francis Nov 2007

Differences In Virulence Among Escherichia Coli O157:H7 Strains Isolated From Humans During Disease Outbreaks And From Healthy Cattle, Diane R. Baker, Rodney A. Moxley, Mike B. Steele, Jeffrey T. Lejeune, Jane Christopher-Hennings, Ding-Geng Chen, Philip R. Hardwidge, David H. Francis

School of Veterinary and Biomedical Sciences: Faculty Publications

Escherichia coli O157:H7 causes life-threatening outbreaks of diarrhea, hemorrhagic colitis, and hemolyticuremic syndrome in humans and significant economic loss in agriculture and could be a potential agent of bioterrorism. Although the prevalence of E. coli O157:H7 in cattle and other species with which humans have frequent contact is high, human infections are relatively uncommon, despite a low infectious dose. A plausible explanation for the low disease incidence is the possibility that not all strains are virulent in humans. If there are substantial differences in virulence among strains in nature, then human disease may select for high virulence. We used a …

Enhancement Of Efficacy Of Prrsv Vaccines By Altering The Glycosylation Pattern Of Viral Glycoproteins, Asit K. Pattnaik Oct 2007

Enhancement Of Efficacy Of Prrsv Vaccines By Altering The Glycosylation Pattern Of Viral Glycoproteins, Asit K. Pattnaik

School of Veterinary and Biomedical Sciences: Faculty Publications

PRRSV, the causative agent of PRRS is of major economic significance to the pork industry in the USA and around the world. Current commercial vaccine does not provide adequate protection against PRRSV outbreaks. Therefore, there is an urgent need for development of more efficacious vaccine to combat PRRS. Our previous studies have suggested that (i) induction of neutralizing antibody response is an important correlate of evaluating the efficacy of a vaccine; (ii) neutralizing antibodies can be enhanced by hypoglycosylation of the major surface glycoprotein (GP5). While it is known that GP5 plays a prominent role in neutralizing antibody induction, it …
