Bovine tropical theileriosis is an important haemoprotozoan disease of domestic and wild bovids, caused by Theileria annulata and transmitted by different species of Hyalomma ticks. It has serious economic impact in view of mortality, reduced milk yield, weight losses, abortions, and control costs associated with the disease. In present report, a case of acute bovine tropical theileriosis is discussed in a cattle with the objective of early diagnosis of Theileriosis infection on the basis of clinical findings collaborating with haematological alterations and presence of Theileria spp. parasite in the blood smear. A crossbred cattle was presented to the Veterinary Clinical Complex, PGIVER, Jaipur, exhibited prominent clinical signs like elevated body temperature, pale mucous membrane, presence of ticks on body of animal, anemia and mild enlargement of superficial lymph nodes. The blood sample was collected with EDTA vial from the same cattle. Confirmation of theileriosis was done by peripheral blood smear examination by Giemsa's staining method..On microscopic examination of blood smear, several piroplasms were noticed within the erythrocytes and schizonts in lymphocytes. The peripheral blood smear revealed higher parasitaemia. The cattle was treated with diminazine aceturate @5mg/kg, IM 2 doses on alternate day and oxytetracycline @ 20mg/kg, IV once daily for 5 consecutive days.along with supportive therapy .The cattle was successfully recovered after one week of treatment.

Canine demodicosis caused by mites in the genus Demodex is a major and common ectoparasitic disease of dogs. In this report, a case of Canine demodicosis is discussed. A white pomeranian female dog aged between 9 and 10 months was presented to the Veterinary Clinical Complex, PGIVER, Jaipur with a history of depression, anorexia, chronic dermatitis associated with pruritus.Upon clinical examination, dogs exhibited papules, pustules, erythema ,alopecia and scaling on the ventral aspects of the chest, all four limbs, the ventral aspect of the neck and around the eyes,erosions, lichenification and cellulitis. Distribution of lesions observed on face, around the eyes and ears, chin region, fore and hind limbs, neck and lateral abdomen. Skin scrapings and tape impression smears were collected from the lesions of affected dog for laboratory examination. By using tape impression smears examination large number of adult short-tail Demodex mites were found. Demodex cornei was identified by based on the morphological characters including short opisthosoma with blind and round terminal end. Dog was treated with daily oral ivermectin @ 500 μg/kg/day, external application of amitraz along with supportive therapy. After six weeks of treatment dog was recovered completely without any side effects.

The present investigation was carried out to record the prevalence, cytopathological and histopathological findings of Sarcocystosis in oesophagus of goat in Jaipur, Rajasthan. In this study, a total of 1115 of digestive tract samples were collected from goats, irrespective of age groups, breeds and sex. Out of the total 1115 samples, 152 representative samples of oesophagus were processed for subsequent cytopathological and histopathological examinations. The results of the present study revealed an overall prevalence of sarcocystosis as 13.63 per cent. After investigated esophagi, the goat had been infected with both types, macroscopic and microscopic cysts for the infection. During gross examination, only in four cases (0.35%) macroscopic sarcocysts noticed, in the form of many white to pale, oval fat (macro), grain sized, multifocal nodules on outer surface and in the majority of cases microsarcocysts were evident in oesophgeal muscles. In cytopathology, giemsa stained impression smears, collected from the oesophagi were found positive for microscopic sarcocysts and banana-shaped bradyzoites in clusters as well as individually. Histopathologically, the study depicted the presence of several forms of microscopic cyst, including spindle, circular, elliptical, cylindrical and twisted form in esophagus. Microscopically, these appeared as blue colour sarcocysts contained bradyzoites in tunica muscularis including both thin-walled and thick-walled. Individual microcyst was surrounded by single layer of muscle fibers and degeneration and necrosis of muscle bundles were prominent. Hence, this study is one of the very few studies which have investigated the cytodiagnosis of zoonotic disease in veterinary sciences. It contributes in the existing literature on cytohistopathological diagnosis of the Sarcocystosis not only in goats but also in other meat producing animals. In present investigation, the prevalence was primarily related to the presence of microsarcocysts in muscles. Thus, microscopic examination of slide impression smears collected from the meat is essential to diagnose the Sarcocystosis for screening of the disease. It is recommended that meat should be cooked sufficiently or frozen before use to prevent health hazards to the consumer.

A total number of 518 samples of small intestine were examined from carcasses of cattle, irrespective of age, sex and breeds. Out of these 151 samples showing gross lesions were collected and tissue sections from these were subjected to histopathological examination. This paper describes two cases of indigestible foreign bodies obstruction observed in small intestine of cattle during this study. The gross changes were dark bluish-red discolouration of intestinal wall and lodgment of intraluminal foreign bodies while microscopically, revealed congestion, pressure necrosis, venous stasis of mucosa and submucosa of intestine.
