Thelazia callipaeda has been regarded in Europe in the last few decades as a "new" agent of an ocular disease in dogs, cats, several wild species, and not least in humans. After the first European description in Italy, in 1989, the parasite has been reported in many other countries, showing a widespread distribution of this parasite. The first case of canine thelaziosis in Romania has been reported in 2015, and it has been followed by other studies confirming the presence of the nematode in dogs or broadening the host spectrum with some wild carnivore species that have been found positive. Despite being considered suitable primary hosts for T. callipaeda, infection with T. callipaeda in domestic cat is rarely reported in Europe, probably due to some behavioral and physical particularities of this host. This study describes the first autochthonous report of T. callipaeda infection in a domestic cat from Romania. Additionally, to these findings, new geographical records of canine thelaziosis are being revealed, confirming the increased risk of this emerging vector-borne zoonosis.

Background: Double chambered right ventricle (DCRV) is a congenital heart anomaly where the right ventricle is divided into two chambers. We describe, for the first time, an unusual combination of DCRV combined with some other congenital heart defects., Case Presentation: A 1.2-year-old Golden Retriever was presented with lethargy, exercise intolerance and ascites. Physical examination revealed an irregularly irregular pulse and a grade V/VI, systolic, right cranial murmur. Electrocardiography revealed widened and splintered QRS complexes with a right bundle-branch block pattern. Radiography demonstrated right-sided cardiomegaly. Two-dimensional echocardiography identified a DCRV with tricuspid valve dysplasia. The patient died despite abdominocentesis and 4 days of oral pharmacotherapy, and necropsy revealed an anomalous fibromuscular structure that divided the right ventricle into two compartments. Another finding was tricuspid valve dysplasia with hypoplasia of the posterior and septal leaflets. The anterior leaflet was prominent, being part of the anomalous structure that divided the right ventricle. Necropsy also identified a perimembranous ventricular septal defect and mild subaortic stenosis. Histopathological examination of the fibromuscular band that separated the right ventricle identified longitudinally oriented layers of dense fibrous connective tissue and myocardial cells arranged in a plexiform pattern. The muscular component was well represented at the ventral area of the fibromuscular band, and was absent in the central zone. Superficially, the endocardium presented areas of nodular hyperplasia covering mainly the fibrous part of the abnormal structure. The nodules were sharply demarcated and were composed by loosely arranged connective tissue with myxoid appearance, covered by discrete hyperplastic endocardium., Conclusions: Concomitant cardiac malformations involving DCRV, tricuspid valve dysplasia, perimembranous ventricular septal defect and mild subaortic stenosis have not been previously described in veterinary medicine, and are reported here for the first time. Moreover, this is the first report of a canine patient with tricuspid valve dysplasia (TVD) and DCRV where the anterior leaflet is part of an anomalous structure dividing the right ventricle (RV) into two separate compartments.

During six years (April 2010-April 2016) we examined individual feces samples collected from 1314 dogs located in Center and Northwest Romania (Transylvania). Stool samples were analyzed by saturated salt flotation, sedimentation technique and modified Ziehl-Nielsen staining method. The overall prevalence of endoparasitic infections was 66.6% (n=875). Sixteen species/genera of endoparasites were identified. The most prevalent species were Ancylostoma caninum/Uncinaria stenocephala (33.0%) (p=0.0001) followed by Trichocephalus vulpis (25.0%). Mixed infections, were significantly more frequent (p=0.0001) than single species infections. The age and the living condition/service of dogs were identified as the main risk factors for infection with endoparasites., (Copyright © 2017 Elsevier B.V. All rights reserved.)

Canine dirofilarioses are mosquito-borne zoonotic diseases with a continuous expansion of their geographical distribution, as a consequence of different climatic and ecological factors. Dirofilaria immitis, the aetiological agent of heartworm disease, has gained a major veterinary interest, mainly due to its severe clinical implication. In the last decades, D. repens, despite of being regarded as a less pathogenic species, regained attention due to its recognized zoonotic potential. Romania has been traditionally regarded as a non-endemic country, but recent epidemiological surveys are highlighting the presence of both D. repens and D. immitis. The present case report describes the clinical and pathological features of a natural co-infection with D. repens and D. immitis in 5year old male Boxer from north-western Romania. Based on clinical and laboratory investigations, a diagnosis of kidney failure and chronical cystitis was established. The parasites were identified by morphology and confirmed by PCR and sequencing. To the best of our knowledge this is the first worldwide report of the ectopic presence of D. repens adults in the pelvic cavity and mesentery by natural infection and first report of the ocular localization of this parasite for Romania. The clinical and paraclinical findings suggest the implication of D. repens microfilariae in the aetiology of histopathological lesions. Further investigations are needed in order to establish the actual pathogenic potential of D. repens, a frequently neglected parasite., (Copyright © 2017 Elsevier B.V. All rights reserved.)

Prostate cancer in dogs belongs to the category of diseases that affect mainly elderly animals. Due to low frequency and slow development of this disease, the diagnosis and staging of these tumours present a challenge. The aim of this study was to highlight the role of contrast enhanced ultrasound in the diagnosis and staging in a case report of prostate adenocarcinoma in Rottweiler aged 7 years. Conventional ultrasound examination of the dog revealed a profoundly altered structure of the prostate, the presence of masses in both the kidney and liver parenchyma with hepatic veins consistent with turgor, and also a hyperechoic content of the gallbladder. Optimization of the examination with contrast substance revealed a vascular pattern of malignancy both in the prostate and kidney, and has excluded any bile and kidney determinations. Pathological examination revealed a primary tumour in the form of an anaplastic prostate adenocarcinoma with multiple secondary determinations in the lung, kidney and bone. Ultrasound enhanced with intravenously administered contrast substance is an optimal imaging technique that provides real-time information on the vascular space replacement formations behaviour in prostate and kidney, with a role in the diagnosis and staging of prostate tumours.
