Two groups of 4 dogs underwent nasal and ethmoidal turbinectomies followed by irradiation (mean minimal doses of 5,390 and 6,550 cGy of radiation, respectively) from implanted intracavitary sources of iridium 192. Two dogs from each group were euthanatized for histologic evaluation at 3 months after irradiation. The remaining 2 dogs from each group were euthanatized for similar evaluation at 6 months after irradiation. During the course of the study, few clinical complications were encountered. Histologic evaluation of the tissues forming the nasal passages revealed loss of epithelial lining and fibrous tissue replacement of surrounding bone. A direct correlation of pathologic changes could not be associated with the amount of radiation received, but there seemed to be a tendency for greater change in those dogs given higher doses and those kept alive for 6 months.

Porcine epidemic diarrhoea virus (PEDV) infection causes watery diarrhoea, vomiting, anorexia, and weight loss, especially among neonatal piglets, inflicting on them morbidity and mortality potentially reaching 90%–100%. Despite it being known that certain mammalian cell phases are arrested by PEDV, the mechanisms have not been elucidated, and PEDV pathogenesis is poorly understood. This study determined the effect of an epidemic PEDV strain on cell cycle progression. We observed the effect of the PEDV SHpd/2012 strain on an infected Vero cell cycle through flow cytometry and Western blot, investigating the interrelationships of cell-cycle arrest, the DNA damage–signalling pathway caused by PEDV and the phosphorylation levels of the key molecules Chk.2 and H2A.X involved upstream and downstream in this pathway. PEDV induced Vero cell-cycle arrest at the G1/G0 phase. The phosphorylation levels of Chk.2 and H2A.X increased with the prolongation of PEDV infection, and no significant cell-cycle arrest was observed after treatment with ATM or Chk.2 inhibitors. The proliferation of PEDV was also inhibited by treatment with ATM or Chk.2 inhibitors. PEDV-induced cell-cycle arrest is associated with activation of DNA damage–signalling pathways. Our findings elucidate the molecular basis of PEDV replication and provide evidence to support further evaluation of PEDV pathogenesis.

Derzsy’s disease and Muscovy duck parvovirus disease have become common diseases in waterfowl culture in the world and their potential to cause harm has risen. The causative agents are goose parvovirus (GPV) and Muscovy duck parvovirus (MDPV), which can provoke similar clinical symptoms and high mortality and morbidity rates. In recent years, duck short beak and dwarfism syndrome has been prevalent in the Cherry Valley duck population in eastern China. It is characterised by the physical signs for which it is named. Although the mortality rate is low, it causes stunting and weight loss, which have caused serious economic losses to the waterfowl industry. The virus that causes this disease was named novel goose parvovirus (NGPV). This article summarises the latest research on the genetic relationships of the three parvoviruses, and reviews the aetiology, epidemiology, and necropsy characteristics in infected ducks, in order to facilitate further study.

In this study, it was aimed to determine the prevalence of ear diseases in cats and dogs brought to clinics in Kocaeli provinces. For this purpose, a general ear examination of 66 cats and 46 dogs brought to the clinic in Kocaeli were performed and the ear canal and eardrum were examined with an otoscope. In addition, a radiographic imaging method (x-ray), as well as microbiological and histopathological examinations were performed. After diagnosing the diseases, they were recorded and evaluations about ear diseases were analyzed statistically.

This study was carried out on 124 dogs between February 2018 and November 2018 to determine the prevalence of gastrointestinal helminths in stray dogs in Van. Collected stool samples, after macroscopic examination, were examined by native, flotation and sedimentation methods in terms of eggs and larvae. According to the results of the study, 43 (34.68%) of 124 dogs were detected as infected with various types of helminths. The most common species were respectively Toxascaris leonina (16.13%), Toxocara canis (12.90%), Ancylostoma caninum (5.64%), Taenia spp. (4.84%), Dipylidium caninum (3.22%), Uncinaria stenocephala (3.22%), Capillaria spp. (3.22%), Fasciola hepatica (2.70%) and Dicrocoelium dentriticum (1.35%) 35.14% of the female dogs were infected with parasites, while this rate was 34% for males. Statistically, infection status in males and females does not differ significantly by gender (Chi-Square: 0,17 p >0.05). When the distribution by age is examined, it is 0.5-2 years with the highest rate of 45.3%, 2-6 years with 27.7% and 5-9 years with 25%. According to age, infection status does not show a statistically significant difference (Chi-Square: 4.64, p> 0.05). As a result, it was concluded that the subsi substantial presence of zoonotic helminths in straydogs in the province of Van poses a threat to human health and protective measures should be taken againstit.

The present study aimed to investigate the prevalence of Salmonella and their antibiotic resistance pattern against two commonly used antibiotics: ciprofloxacin and ceftriaxone in marketed live chickens in a live birds market. Materials and methods: The study was conducted on live Sonali chickens (crossbred of Fayoumi female and Rhode Island Red male). Cloacal swabs were collected from 50 randomly selected live birds from 5 retail sellers (10 samples/seller) at Jhawtola live birds’ market, Chattogram, Bangladesh. Culture and biochemical tests were used to identify Salmonella. Positives samples for Salmonella were further tested for antibiogram by disc diffusion method.Salmonella was identified from 28 (56%) of samples by culture and biochemical test. Among the positive isolates, 27 (96.42%) samples exhibited resistant to ceftriaxone, and 20 (71.42%) samples were to ciprofloxacin.The result of this study indicates there is a high prevalence of Salmonella in marketed local chicken and are resistant to ceftriaxone and ciprofloxacin which has economic importance as well as a public health concern. Awareness should be increased to prevent random use of antibiotics and provision of strict biosecurity measures.

The study was conducted to determine the prevalence of Peste des Petits Ruminants in different breed of goats based on age, sex, seasonal variation and vaccination status at Upazilla Veterinary Hospital, Pirojpur Sadar, Bangladesh during the period from January 2015 to December 2015. A total of 319 cases of different breed of goats were recorded in which 43 (13.48%) were infected by Peste des Petits Ruminants. The diagnosis of Peste des Petits Ruminants was performed based on clinical history, clinical signs and some laboratory techniques. The major clinical signs were high fever, nasal discharge, rapid breathing, mouth lesions and bloody diarrhea.The prevalence was highest in Black Bengal goat (6.90%) compare to Jamunapari (3.76%) and crossbreds (2.82%). Female goats were more susceptible (60.47%) than the male goats (39.53%). 5 months to 11 months aged goats showed highest prevalence (48.84%) followed by 1 to 3 years aged goats (27.91%) and 0 to 4 months aged goats (23.26%). In winter season, the prevalence was highest (55.81%) compare to summer (25.58%) and rainy season (18.60%). The non-vaccinated goats were more susceptible (90.91%) than the vaccinated goats (9.09%).Those prevalence of Peste des Petits Ruminants in different breed of goats based on age, sex, seasons and vaccination will help clinician to know the occurrence of Peste des Petits Ruminants in this area and will help them to take proper preventive measures.

This study was carried out to investigate the gastrointestinal helminthes of dogs in Udgir area. Materials and This study consisted of 218 dogs over period of 10 months. A total of 218 faecal samples collected over a period of 10 months from dogs in Udgir area were subjected to fecal sample examination by standard parasitological procedures.An overall prevalence to the tune of 31.65% was noted. The major helminthes parasites recovered were Ancylostoma caninum (66.67%), Ancylostoma braziliense (4.35%), Toxocara canis (26.08%) and Dipylidium caninum (2.89%).There were non-significant differences in age wise and sex wise distribution of helminthes infecting dogs of the area.

Objective—To evaluate the long-term protective immunity of a cyprinid herpesvirus 3 (CyHV3) vaccine in naïve koi (Cyprinus carpio koi). Animals—72 koi. Procedures—Vaccinated koi (n = 36) and unvaccinated control koi (36) were challenge exposed to a wild-type CyHV3 strain (KHVp8 F98-50) 13 months after vaccination. Results—The CyHV3 vaccine provided substantial protective immunity against challenge exposure. The proportional mortality rate was less in vaccinated koi (13/36 [36%]) than in unvaccinated koi (36/36 [100%]). For koi that died during the experiment, mean survival time was significantly greater in vaccinated than in unvaccinated fish (17 vs 10 days). Conclusions and Clinical Relevance—The CyHV3 vaccine provided substantial protective immunity against challenge exposure with CyHV3 13 months after vaccination. This provided evidence that koi can be vaccinated annually with the CyHV3 vaccine to significantly reduce mortality and morbidity rates associated with CyHV3 infection.

Objective: To compare myocardial cytokine expression in dogs with naturally occurring cardiac or systemic diseases and dogs without cardiac or systemic diseases (control dogs). Sample: Myocardial tissue samples from 7 systemic disease-affected dogs (SDDs), 7 cardiac disease-affected dogs (CDDs), and 8 control dogs. Procedures: mRNA expression of interleukin (IL)-1, IL-2, IL-4, IL-6, IL-8, IL-10, tumor necrosis factor (TNF)-α, interferon (IFN)-γ, transforming growth factor (TGF)-β1, TGF-β2, TGF-β3, and growth differentiation factor-15 in myocardial tissue samples obtained from CDDs, SDDs, and control dogs were analyzed via quantitative PCR assays. Results: In control dogs, only mRNA for TNF-α, TGF-β1, and TGF-β3 was detected; concentrations were significantly higher in male than in female dogs. In SDDs and CDDs, all cytokines, growth factors, and growth differentiation factor-15 were expressed. Compared with findings in SDDs, IL-1, IL-6, IL-8, IL-10, TNF-α, and IFN-γ expression was significantly increased in CDDs; specifically, IL-1, IL-8, TNF-α, TGF-β1, and TGF-β3 expression was increased in the atria and IL-8, IL-10, TNF-α, and IFN-γ expression was increased in the ventricles of CDDs. Conclusions and Clinical Relevance: Data suggested that the alterations in cytokine expression in SDDs and CDDs, compared with control dog findings, were a result of inflammatory system activation. The differences in cytokine expression in atria and ventricles between SDDs and CDDs were suggestive of different remodeling processes. A better knowledge of myocardial involvement in SDDs and of immune regulation in CDDs might beneficially affect morbidity and mortality rates and provide new treatment approaches.
