Leptospirosis is a bacterial zoonotic disease that causes abortions, infertility and mastitis in cattle. This research was aimed at investigating the temporal and spatial pattern, sex, age, breed wise distribution of leptospirosis in Tamil Nadu. A seroreactivity of 28.2% was noticed among cattle in seven agro-climatic zones. The temporal trend of leptospirosis recorded during the post-monsoon season (30.5%) was significant when compared to the pre-monsoon season (25.8%). The spatial distribution revealed a high proportion of leptospirosis (31.2%) in the North East zone in comparison with the other zones. The serogroups Australis (37.9%), Hebdomadis...

Haematological indicators may resent physiological variation by age. Vitamin B12 promotes haematopoiesis. The aims of this study were: 1) to compare the values of the haematological variables and the concentration of vitamin B12 in pre- or post-weaned veal calves and 2) to identify the possible association between the values of the haematological variables and the concentration of B12 in the blood of veal calves. Blood was collected on the same day from 31 pre-weaned and 31 weaned calves of the Limousine breed from the same farm. The complete blood count, including the blood cell morphology evaluation, was performed and the serum B12, total protein...

Glucocorticoids (GCs) cause excess fat accumulation, which leads to fertility dysfunction in broilers. The study investigated alterations in the morphology and morphometry of the testes of broilers in response to GC and dexamethasone (DEX). Male day-old chicks were randomly divided into a control group and three experimental groups (E1, E2, and E3). The control group was fed a commercial broiler ration. The experimental groups were fed a commercial broiler ration containing GC (i.e. DEX 3, 5, and 7 mg/kg, respectively). The testes were collected and stained with haematoxylin and eosin to count the number of testicular seminiferous tubules. An increase...

Sodium chloride is widely used in aquaculture due to its antiparasitic effects and its ability to reduce stress during fish transport and manipulation. The aim of this study was to assess the safety of short-term exposure to sodium chloride for the common carp (Cyprinus carpio). In our experiment, fish were placed into a sodium chloride bath (c = 30 g l^-1; T = 30 min; t = 20 °C) and the effects of the treatment were assessed immediately after the bath (T0) and 24, 48 and 240 h later (T24, T48 and T240, respectively), with non-treated fish serving as control groups. Though significant differences compared to the controls were observed...

An 8-year-old, neutered male Yorkshire Terrier dog presented with left ventromedial canthus swelling over a one-month period, refractory to pharmacological therapy. There was no history of trauma. On ultrasonography, the lesion had a cystic character filled with anechoic fluid and hyperechoic sedimenting debris. The computed tomography (CT) and CT-dacryocystography showed a cystic lesion protruding from the lacrimal sac fossa and occupying a defect in the orbital plate and an ethmoidal ectoturbinate surrounded by a bony structure with an intact nasolacrimal system. The dog underwent the surgical resection of the cyst and its fluid content was aspirated....

Congenital ichthyosis in a Maltese dog: A case reportCase Report

This case report describes congenital ichthyosis in a Maltese dog, a condition, which has not previously been reported in this breed. The dog presented with several dry, tightly adhering scales showing a multi-focal appearance. The histology revealed severe orthokeratotic hyperkeratosis and hyperplasia with an irregular granular layer without epidermolysis. Non-epidermolytic ichthyosis (NI) has strong breed predilection in dogs, and its morphological features vary by breed while the microscopic changes are similar. It is likely to be the first reported case of congenital ichthyosis in a Maltese dog showing a different morphological appearance compared...
