Parasites Of Caribou (2): Fly Larvae Infestations

Zoonotics and Wildlife Disease: Publications

All wild animals carry diseases. In some cases these might be of concern if they can spread to humans or domestic animals. In other cases they might be of interest if they impact on the health of our wild herds, or simply because the signs of the disease have been noticed and you want to know more.
This fact sheet is one of a series produced on the common diseases of caribou and covers the larval form of two different flies commonly seen in this province. Neither of these are a cause of public health concern.

Parasites Of The Snowshoe Hare (1): Tapeworm Cysts

Zoonotics and Wildlife Disease: Publications

All wild animals carry diseases. In some cases these might be of concern because they can spread to humans or domestic animals. In other cases they may be of interest simply because the signs of the disease have been seen and you want to know more. Though diseases are relatively common in these animals there is usually an increase in reporting when the hare populations are at a peak. High populations mean that there is an increased chance of one animal infecting another. In addition, when there are too many animals in one area, the amount of available food is …

Keep Your Cabin Free Of Rodents

Zoonotics and Wildlife Disease: Publications

Cabins that have been closed for the winter can become nesting sites for mice, shrews and other rodents. These animals can carry fleas, ticks, viruses or other organisms on their skin, in their droppings or urine. These can cause diseases in humans, especially when you breathe in the dust from their droppings or nesting sites.
Avoid close contact with rodent urine, droppings, nesting materials or with any food or surfaces contaminated with them.
Always wear rubber gloves when handling dead rodents, or when cleaning traps, droppings, nesting sites or other areas that rodents may have visited.

Neuroanatomical Structure Of The Spinner Dolphin (Stenella Longirostris Orientalis) Brain From Magnetic Resonance Images, Lori Marino, Keith Sudheimer, William A. Mclellan, John I. Johnson

Veterinary Science and Medicine Collection

High-resolution magnetic resonance (MR) images of the brain of an adult spinner dolphin (Stenella longirostris orientalis) were acquired in the coronal plane at 55 antero-posterior levels. From these scans a computergenerated set of resectioned virtual images in the two remaining orthogonal planes was constructed with the use of the VoxelView and VoxelMath (Vital Images, Inc.) programs. Neuroanatomical structures were labeled in all three planes, providing the first labeled anatomical description of the spinner dolphin brain.

Relative Importance Of Heat-Labile Enterotoxin In The Causation Of Severe Diarrheal Disease In The Gnotobiotic Piglet Model By A Strain Of Enterotoxigenic Escherichia Coli That Produces Multiple Enterotoxins, Emil M. Berberov, You Zhou, David H. Francis, Michael A. Scott, Stephen D. Kachman, Rodney A. Moxley

School of Veterinary and Biomedical Sciences: Faculty Publications

Enterotoxigenic Escherichia coli (ETEC) strains that produce multiple enterotoxins are important causes of severe dehydrating diarrhea in human beings and animals, but the relative importance of these enterotoxins in the pathogenesis is poorly understood. Gnotobiotic piglets were used to study the importance of heat-labile enterotoxin (LT) in infection with an ETEC strain that produces multiple enterotoxins. LT^- (ΔeltAB) and complemented mutants of an F4⁺ LT⁺ STb⁺ EAST1⁺ ETEC strain were constructed, and the virulence of these strains was compared in gnotobiotic piglets expressing receptors for F4⁺ fimbria. Sixty percent of the piglets …

Physiological Reactions Of Poultry To Heat Stress And Methods To Reduce Its Effects On Poultry Production, Narongsak Chaiyabutr

The Thai Journal of Veterinary Medicine

Thermal environment is regarded as the prime factor governing the production because, both the feed consumption and heat production are related closely to the thermal environment. Therefore, heat stress is caused by a combination of environmental and animal factors that result in reduced performance as the animal attempts to cool itself. In this review, the physiological reactions of bodily functions during heat exposure in poultry are described. Thermal panting, the marked response of poultry to heat stress, is compensatory behavior to permit a high rate of evaporative cooling from the respiratory tract. Cardiorespiratory responses to thermal stress show different patterns …

The Thai Journal of Veterinary Medicine

Archived paraffin-embedded lymphoid tissue samples from seventy five experimental PRRSV-infected pigs were examined for PRRSV antigen and IFN-γ positive cells, using immunohistochemistry. Lymphoid tissues (5 pigs/group) including spleen, tracheobronchial lymph nodes and tonsil came from negative control pigs (group 1), low virulence strain of PRRSV (RespPRRS/ReproTM, modified-live virus vaccine) infected pigs (group 2) and high virulence strain of PRRSV (VR-2385) infected pigs(group 3). They were necropsied at 3, 7,10, 14 or 28 days post-inoculation (DPI). According to the study, microscopic lesions in the lymphoid tissues from pigs infected with the high virulence strain had more severe lesions, characterized by severe …

The Function Of The Oviduct In Relation To Sperm Transport And Capacitation In Swine, Paisan Tienthai

The Thai Journal of Veterinary Medicine

In the pig, sperm transport is regulated, to facilitate normal fertilization of the ovulated oocytes, by the oviduct which contains a particular segment, the sperm reservoir. The main function of the sperm reservoir is to ensure that stored spermatozoa have maintained viability and fertilizing capacity. The process of sperm capacitation is delayed in the sperm reservoir, during the lengthy pre-ovulatory estrus by interactions between the spermatozoa, the oviduct epithelium and secretion products. Sperm capacitation seems to be facilitated by the tubal fluid in the upper segment of the oviduct releasing sperm from the reservoir in relation to the time of …

The Estimation Of Glomerular Filtration Rates Using Endogenous Creatinine Clearance In Nine Dogs, Chollada Buranakarl, Wanchai Yenpetch, Siram Suvarnavibhaja

The Thai Journal of Veterinary Medicine

The objective of this study was to estimate the glomerular filtration rates of normal dogs using the clearance of endogenous creatinine, and comparing it to the clearance of exogenous creatinine. Nine healthy dogs, of both sexes, were used in this study. The results showed a significant relationship, with a correlation coefficient = 0.714 (p<0.05). The regression line was an endogenous creatinine clearance = (-0.803 + 0.677) x exogenous creatinine clearance. The use of endogenous creatinine clearance is a simple and convenient method without the need to administer any substances and can be used to evaluate renal function in clinical practice.

Pcr-Rflp Analysis In An Open Reading Frame 5 Of Variants Of Prrsv Isolated In Thailand, Nusara Punprapa, Anudep Rungsipipat, Amornrat Tatsanakit, Piya Wongyanin, Roongroje Thanawongnuwech

The Thai Journal of Veterinary Medicine

Ten selected Thai isolates of Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) were amplified in an open reading frame 5 by a reverse, transcriptase, polymerase chain reaction (RT-PCR) and cut with restriction enzymes: MluI, HincII, SacII and HaeIII for the US genotype and PstI, HaeII and ClaI for the EU genotype. None of the field isolates had a similar cutting pattern when compared to modified live virus vaccines, however, several cutting patterns were obtained from this study. The results suggested that genetic variation was present among the Thai isolates, even within the same genotype. The variations may be the result …

The Effect Of Parity Number, Body Condition Score, Backfat Thickness And Weaning To Oestrus Interval On The Time Of Ovulation In Sows, Woravit Anuvongnukroh, Chaowaphan Yinharnmingmongkol, Sutthatip Punieam, Padet Tummaruk, Annop Kunavongkrit

The Thai Journal of Veterinary Medicine

The present study was performed to study the time of ovulation in 53 weaned sows, by using real time B-mode ultrasonography and to study the influence of parity, body condition score, backfat thickness and weaning-to-oestrus interval on the time of ovulation. The study revealed that ultrasound B mode successfully determined the time of ovulation in 37 sows. Parity number, weaning-to-oestrus interval and oestrus duration influenced the ovulation time, whereas backfat thickness and body condition score was not correlated with either the ovulation time or the duration of oestrus.

The results from 34 milkings at farm 1 and 28 milkings at farm 2 showed that the amount of colostrum obtained was 96.77±38.63 ml and 114.93±75.09 ml, respectively, taking an average of 19 mins/milking with no damage to the udder. The second part of the study was to manually feed 9 ml of the colostrum, obtained from …

Rabies In Newfoundland & Labrador

Zoonotics and Wildlife Disease: Publications

Rabies is a deadly viral disease of the brain spread by the bite of infected mammals. It is most commonly seen in red or arctic foxes in this province though other wild animals such as bats may carry the disease. Sick foxes can bite other foxes, dogs, cats, wolves, caribou, other animals and people and make them sick. Once bitten by an animal with rabies it can take from two weeks to six months before the animal shows signs of the disease. Though uncommon, this period can be as short as 4 days or as long as a year or …

Identification Of A Novel Bovine Herpesvirus 1 Transcript Containing A Small Open Reading Frame That Is Expressed In Trigeminal Ganglia Of Latently Infected Cattle, Melissa Inman, Joe Zhou, Heather Webb, Clinton J. Jones

School of Veterinary and Biomedical Sciences: Faculty Publications

Bovine herpesvirus 1 (BHV-1), like other Alphaherpesvirinae subfamily members, establishes latency in sensory neurons. The latency-related (LR) RNA is abundantly expressed during latency, and expression of an LR protein is required for the latency reactivation cycle in cattle. Within LR promoter sequences, a 135-aminoacid open reading frame (ORF) was identified, ORF-E, that is antisense to the LR RNA. ORF-E is also downstream of the gene encoding the major viral transcriptional activator, bICP0. Strand-specific reverse transcription-PCR demonstrated that a transcript containing ORF-E was consistently expressed in trigeminal ganglia (TG) of latently infected calves, productively infected cultured cells, and acutely infected calves. …

“French Heartworm” Infection Of Dogs & Foxes In Newfoundland

Zoonotics and Wildlife Disease: Publications

French Heartworm is the common name for a parasitic disease affecting foxes, dogs, and other members of the dog family. Caused by the nematode (worm) Angiostrongylus vasorum, this disease was first thought to exist in France in the mid 1800's. It is now considered to exist generally in Europe but has not been reported in North America other than on the Island of Newfoundland, with the exception of infected animals imported from Europe but diagnosed in North America. The first case recorded in Newfoundland was in Aquaforte (Avalon Peninsula) in 1973.
When and how it might have come over …
