The prevalence of Dirofilaria repens in dogs in countries bordering Slovenia ranges from 1.5% to 47.3%. The aim of this study was to estimate its prevalence in Slovenian dogs and to present the cases of dirofilariasis diagnosed in humans from 2010 to 2020.

Introduction: In the present study apoptosis was investigated in the cornu ammonis and cerebellum of 10 dogs naturally infected with rabies virus. Diagnosis of rabies was based on the results of fluorescent antibody staining and experimental inoculation.

While the current tools to assess canine postoperative pain using physiological and behavioural parameters are reliable, an objective method such as the parasympathetic tone activity (PTA) index could improve postoperative care. The aim of the study was to determine the utility of the PTA index in assessing postoperative analgaesia.

Leishmaniasis is a life-threatening zoonosis of which dogs are the major reservoir and sandflies are the vectors. Until now, the prevalence of canine leishmaniasis (CanL) in the Slovenian dog population was unknown.

Introduction: The aim of the study was to investigate the presence of human papillomaviruses (HPV), mouse mammary tumour virus (MMTV), Epstein-Barr virus (EBV), and human polyomavirus BK in canine mammary tumours (CMTs) and to correlate the results of histopathological classification with the results of virological examination. Material and Methods: Eighty CMTs and ten normal canine mammary gland samples were evaluated using histopathological methods and TaqMan real-time PCR analysis. Results: The results indicated that all mammary tumours and normal mammary tissue samples were negative for HPV16 and other HPV, EBV, human polyomavirus, and human mammary tumour virus strains. Conclusion: Further studies should be performed to investigate the existence of other strains of HPV, EBV, and human polyomavirus in CMTs.

Improvements in veterinary medicine have resulted in a significant benefit in the life of pets in the last 20 years, and increased pet life expectancy led to an increased prevalence of canine neoplasia. Cancer epidemiology and spatial analysis tools, although well developed for human oncology research, is just beginning to be explored in veterinary oncology. São Paulo city, capital of the state of São Paulo, Brazil, is divided into five regions: North, South, East, West and downtown. The Veterinary Hospital of the School of Veterinary Medicine and Animal Science, University of São Paulo (HOVET-SVMAS-USP), is located in the West region of São Paulo, Brazil, and admits cases of small and large animals. Canine mammary tumors are so numerous that they are not routinely treated at the HOVET. The aim of this work was to perform a cartographic study to describe the spatial distribution of prevalent cases of neoplasms in dogs from the HOVET. Of the 3,620 cases seen in 2002 and 2003, 380 cases (10.5%) were of dogs affected with benign and malignant neoplasms. No statistical difference was found for the 380 addresses distributed among the five regions of the city. These results showed that the HOVET receives canine patients from all regions of São Paulo and there is a homogeneous spatial distribution of neoplasms. Authors encourage additional broader studies, involving several veterinary hospitals, clinics or laboratories in order to obtain more accurate data on distribution of canine neoplasms in São Paulo, SP, Brazil.

This study investigated the prevalence, risk factors and species composition of ticks, fleas and lice infesting dogs and cats in and around Hawassa in southern Ethiopia. In total, 200 dogs and 100 cats were examined from November 2008 to April 2009. Of the dogs and cats examined, 99.5% and 91.5%, respectively, were infested with one or more species of ticks, fleas or lice. The overall prevalence was higher in dogs than in cats. A total of six different species of ectoparasites were collected and identified from dogs, but only three species from cats. Ctenocephalides felis was the predominant species amongst the animals, with a prevalence of 82.9% on dogs and 67% on cats. Other prevalent species on dogs included Ctenocephalides canis (73.8%), Heterodoxus spiniger (4%), nymphs of Amblyomma spp. (3.5%), Pulex irritans (2.5%) and Haemaphysalis leachi (0.5%). C. canis (18%) and P. irritans (6%) were also found on cats. More female than male fleas and lice were observed. The study revealed that the prevalence of fleas, ticks and lice on dogs was not significantly different between male and female animals or between young and adult dogs. However, the prevalence of these ectoparasites was significantly higher in female than in male and in adult than in young cats. The study showed that the prevalence of ectoparasites on both dogs and cats was significantly higher on animals with flea allergy dermatitis (FAD) than those without FAD, and on animals with lesions on their skin compared with those without lesions.

A penta-dog inactivated cell culture vaccine was prepared to protect dogs againstcanine distemper virus, canine parvovirus, canine adenovirus1, 2 and rabies virus.The potency of this vaccine was compared with that of single inactivated vaccinesprepared against each disease, in different groups of susceptible dogs. It was foundthat the protective dose of penta-dog vaccine (2ml) including the protective amounts of the five viral proteins resulted in full protection of vaccinated dogs against the challenge with virulent strain of the used viruses showing no antagonizing effect between each other with and no adverse postvaccinal reaction. So, the prepared inactivated cell culture penta-dog vaccine is a safe and potent vaccine for dogs which resulted in saving time, cost, and effort stress factors on animals and providing good immune statues.

Staphylococcus pseudintermedius infections present a serious challenge because of the emergence of resistance to numerous conventional antibiotics. Antimicrobial peptides are novel alternatives to traditional antibiotics due to their unique mechanism of action. In this study, we investigated the antibacterial activity of 12 short synthetic peptides against two clinical isolates of S. pseudintermedius isolated from two dog cases with ophthalmic lesions. In addition, the ability of the peptides to disrupt the established biofilm of these two S. pseudintermedius isolates was investigated. RRIKA and 5RHH showed good antimicrobial activity with MICs 2 and 4 µg/ml, respectively. IK8aIID and Indolicidin showed antimicrobial activity with MICs 8 and 16 µg/ml, respectively. Indolicidin, 5RHH and IK8aIID showed a significant biofilm mass % reduction up to 90%.  Taken together, these results support the potential use of antimicrobial peptides for the treatment of S. pseudintermedius infections.

Leptospirosis is a systemic disease caused by the species of bacteria Leptospira spp., which affects human beings, domestic and wild animals. The present study searched the presence of antibodies against Leptospira spp. in the canine population of the city Teresina, Piauí, and the most common serovars. Blood samples from 425 stray dogs were collected in the local zoonosis center in Teresina from July 2010 to January 2012 and submitted to the Microscopic Seroagglutination Test (MAT). This study found an average infection rate of 17.41% (IC 95%; 13,8 – 21,0) by 11 different serovars; the four most frequent were Canicola (18.9%), Autumnalis (16.2%), Icterohaemorrhagiae (12.1%), and Butembo (12.1%). The questions raised in this study indicated the occurrence of Leptospira spp infection in dogs of Terezina- Piaui, Brazil.
