S.; Kolomak, I. O.; Kravchenko, S. O.; Dmytrenko, N. I.; Burda, T. L.Histological examination of testicular tumours in cryptorchid males allows determining the nature of neoplasia, prognosis of long-term consequences in the form of metastases, and defining the optimal method of treatment of the animal, which determines the relevance of research in this area. The aim of the work is to determine the pathohistological structure of neoplasia of the left, cryptorchid, and morphology of the contralateral testes in a Yorkshire Terrier male with unilateral cryptorchidism. General clinical, ultrasonographic, radiological and histological methods were used in the examination of the animal. The article presents data on a mixed tumour of the intraperitoneal left testis of a 6-year-old Yorkshire Terrier, which is an atypical clinical case. It was found that the characteristic ultrasonographic features of the cryptorchid left testis tumour were numerous isoechoic foci of different diameters (from 4 to 26 mm), hyperechoic septa, and tuberous contours with a hyperechoic capsule. At laparotomy, the altered testis had an uneven surface saturated with blood vessels. The section showed milky-white neoplastic areas separated by fibrous bands that did not correspond to the normal structure of the organ. Histological examination of the parenchyma revealed areas of similar rounded cells in the form of a group of shapeless masses separated by a fibrous barrier. Neoplastic tubules had a developed fibrovascular stroma with an eosinophilic necrotic area. The protein membrane also had numerous fibrous formations. The layers of multifaceted cells were located perpendicular to the basal lamina, often with central necrosis, and the testicular mass contained multifocal haemorrhages. Such signs are characteristic of the lesion of Sertoli cells and interstitial Leydig cells, which indicated a mixed type of tumour of the left extraperitoneal testis of the Yorkshire Terrier. The contralateral right testis was unchanged and corresponded to the natural morphological and histological structure. The prostate was normal on macroscopic and histological examination, which has not been previously reported. Six-month follow-up of the dog showed no signs of metastatic process. The practical significance of the work is to obtain new scientific knowledge about the development of mixed tumours of the testis in cryptorchid males and the prospects for the treatment of diseased animalsItem An Investigation of Embryo and Eggshell Development in Trichuris suis (Nematoda, Trichuridae) under Laboratory Conditions(2016-06-15) Yevstafieva, V.

I.; Сизоненко, Наталія Миколаївна; Syzonenko, N. M.; Опара, Надія Миколаївна; Opara, N. M.Dirofi lariasis is a zoonotic disease of domestic and wild carnivorous animals and humans. Subcutaneous migration of the parasite Dirofi laria repens Railliet & Henry, 1911 can lead to the local swellings with changeable localization. In humans, this parasite can cause the damage of lungs, male genitalia, and eyes. Th e range of D. repens is constantly spreading to new areas, and, considering the zoonotic potential of this parasite, it is important to widen the existing data concerning the morphology of D. repens. Present study provides the morphometric description of nematodes D. repens, obtained from subcutaneous tissue of dogs in Ukraine. Th e aim of this study was to make an accent on the key features for performing the identifi cation of parasites of this species. For males, 27 morphometric traits were identifi ed, characterising the total size of the body and the esophagus, the thickness of the cuticle in the region of the mouth opening, the localisation of the nerve ring and the cloaca, the morphological structure and metric parameters of the spicules, and the length of the tail. For females, 18 morphometric traits were identifi ed that, in addition to the common parameters, characterise cuticle thickness in the region of the vulva, localisation of the vulva and anus, body width in the regions of the anus and vulva, and tail length. Th is report widens the existing data on the morphological and metric characteristics of nematodes D. repensItem DIAGNOSIS AND ACTIONS FOR LIQUIDATION OF DOGS STREPTOCOCCOSIS IN PRIVATE NURSERY(2019) Peredera, R.
