Nasal Squamous Cell Carcinoma In A Cow, Ali Baniadam, Navid Moezzi, Babak Mohammadian

Turkish Journal of Veterinary & Animal Sciences

A patient with a turgid, hemorrhagic mass infected by myiasis in the left nostril and diagnosed as squamous cell carcinoma (SCC) is presented. Complete blood count (CBC) showed moderate neutrophilia and eosinophilia and vital signs were in normal range. After aseptic surgical preparations and local anesthesia, the mass removed en bloc and submitted to the Department of Veterinary Pathology for histopathological evaluation. SCC was recognized microscopically by identifying malignant epithelial cells demonstrating various degrees of differentiation towards keratinocytes.

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.

Isolation And Characterization Of Vibrio ( Listonella) Anguillarum From Catfish, Mehrnaz Rad, Davar Shahsavani

Turkish Journal of Veterinary & Animal Sciences

Vibrio anguillarum was isolated from several organs of some aquarium catfish in a fish population with high mortality. Macroscopic examination of the affected catfish revealed ascites in the abdomen, site-petechiae, and dorsal erection. Although there are some variations in phenotypic characterization among different isolates of Vibrio anguillarum, the majority show a common biochemical profile with distinct microscopic appearance that can provide presumptive identification of Vibrio anguillarum. Biochemical tests were used for identification of Vibrio anguillarum in aquarium catfish in this report.

Factors Affecting Wool Characteristics Of Kari Sheep In Pakistan, Sohail Ahmad, Muhammad Sajjad Khan, M. Fatah Ullah Khan

Turkish Journal of Veterinary & Animal Sciences

The present study attempted to generate some basic information on wool production and quality in the Kari breed. Thirty flocks, 10 each in the 3 Union Councils (UCs), were registered for on-farm performance recording in the Lotkho Tehsil, north of Chitral city. Two animals per flock were selected for collecting fleece samples from 3 yearly shearings. The actual greasy wool yield per sheep was 937 g. Wool yield per shearing averaged 366 ± 9.6 g. Location and flock differences were found significant (P < 0.01). The same was also true for the clean fleece yield with an overall average of 300 ± 8.2 g per shearing. The fibre diameter averaged 23 ± 0.2 µm, and flock differences were significant (P < 0.01). The staple length varied among flocks (P < 0.01), locations, and shearing season (P < 0.05). Male Kari had more medulated fibres than female Kari (6.9 ± 0.37% vs. 5.5 ± 0.37%). The greasy and clean fleece yields were quite repeatable traits (repeatability > 0.5). The repeatability estimates of fibre diameter and staple length were 0.38 and 0.20, respectively. Sheep of …

United States Department of Agriculture Wildlife Services: Staff Publications

Context. Feral pigs represent a significant threat to agriculture and ecosystems and are disease reservoirs for pathogens affecting humans, livestock and other wildlife. Information on the behavioural ecology of feral pigs might increase the efficiency and effectiveness of management strategies.

Aims. We assessed the frequency of promiscuous mating in relation to oestrous synchrony in feral pigs from southern Texas, USA, an agroecosystem with a widespread and well established population of feral pigs. An association between multiple paternity of single litters and synchrony of oestrous may indicate alternative mating strategies, such as mateguarding.

Methods. We collected gravid sows at …

Detection And Molecular Characterization Of Canine Enteric Viruses In Southern Ireland., Susan Mcelligott

Theses

Enteric viruses, such as canine parvovirus (CPV) and canine coronavirus (CCoV), are a major cause of gastroenteritis in dogs. More serious clinical symptoms occur in young pups, or when both of these viruses infect an animal simultaneously. Caliciviruses and rotaviruses can also cause gastroenteritis in dogs, but these viruses, while causing significant problems in other animal species and humans, are considered to be less significant pathogens of canines. However, on occasion, these viruses have been reported to produce severe clinical symptoms such as vomiting, haemorrhagic enteritis and severe dehydration.

Many viral vaccines for canines are formulated using old vaccine viral …
