A nine months male cat was presented with the history of itching and scratching over the face, ears and forelimb since a month. On physical examination alopecia, scales, crusty, thick, wrinkled and leathery lesions were found on the face and ears. All the vitals were within the normal range. Microscopic examination of the skin scrapping revealed Notoedres cati. Further history also revealed the presence of pruritus and cutaneous lesions on the shoulder and arm region of the owner. The cat was treated with Inj.Ivermectin @200 µg/kg along with topical application of sulphur (10%).

Ranula rarely resolve without surgery and marsupialisation is easily applicable technique to manage sublingual salivary mucocele. A two year old male German shepherd dog was presented to Veterinary Clinical Complex, Veterinary College and Research Institute, Namakkal with the history of swelling on ventral aspect of the tongue for the past one and half month. The fine needle aspiration cytology revealed macrophages mixed with coccobacillary clumps, haematobiochemical parameters were within the physiological range. Based on the clinical signs, the case was diagnosed as ranula. Under atropine sulphate and xylazine hydrochloride premedication, induction of anaesthesia with ketamine and diazepam followed by isoflurane maintenance, marsupialization was done.  Postoperatively, the animal was treated with broad spectrum antibiotic and antiinflammatory drugs for five days, and the animal recovered uneventfully after 15 days.

Bacterial infection followed by implant fixation is a common complication after surgery. In order to reduce the incidence of implant-associated infections, several biomaterial surface treatments have been proposed. In this study, the effect of in vitro antibacterial activity of magnetron sputtered silver nanoparticles was studied. Sputtering was done using radiofrequency magnetron sputtering technology. Film applicator coating assay was used to assess the antibacterial effect of the coated titanium implants. SEM examination revealed successful deposition of silver nanoparticles on the titanium surface. The average diameter of the nanoparticles was 40-60 nm. SEM examination before incubation and after incubation of bacteria was done. The bactericidal ratio between the uncoated and coated implant was determined.

The study was carried out on male zebrafish containing technical grade deltamethrin (98.5%). A total of 20 males were randomly divided into two groups (Group I) and Group II (Group II) and their pre-exposure spawn count, fecundity, and embryo mortality were calculated at weekly intervals within each group. Results show significant (p0.05 and 0.01) reduction in total count of embryos over 21 days in Group I. Similarly, in Group II it was 36.49 0.54, 72.740.09 and 86.370.06 at 7, 14 and 21 days respectively postexposure of males to deltamethionine.

Leptospirosis is one of the most important zoonotic disease caused by the pathogenic leptospires Leptospira interrogans. In this study, four pathogenic Leptospira serovars were selected based on the seroprevalence data, their LPS extracted, assessed for its purity and seroreactivity and processed for the determining the fatty acid profiles. The average concentration of the LPS extracted from the cultures across the serovars was 742.75+19.4 µg/ml with the polysaccharides contributing to 77.2 % of the LPS (573.6+18.01 µg/ml). The common fatty acids that were present in all the four serovars included butyric acid (C4:0), capric acid (C10:0), palmitoleic acid (C16:0),  eicosapentaenoic acid (C20:5n3) and docosapentaenoic acid (C22:6n3). The heptadecanoic acid (C17:1) was present in serovars australis and autumnalis; pentadecanoic acid (C15:0) in canicola and hardjo serovars and caproic acid (C6:0) in the serovars autumnalis and canicola. The fatty acid eicosatrinoic acid (C20:3n3) was unique to the serovar autumnalis and the myristic (C13:0) and docosadienoic acid (C22:2) being unique to the serovar hardjo. Future studies to understand the fatty acid profile of the other common pathogenic circulating Leptospira LPS will add scientific evidence to the minor cross-reactivity observed across the serovars in MAT.

Mammary tumours are considered as the most important neoplasms in dogs especially in sexually intact female dogs. Prognosis is directly associated with various factors such as tumour size, metastases, involvement of lymph node, tumour type and grade. Recently, tumour microenvironment (TME) has gained huge importance and proved to be a key regulator of breast cancer's biologic behaviour, according to mounting data. The capacity of extracellular matrix components like collagen to alter their intrinsic structure and alignment aids in tumour invasion and metastasis. We present a case study of 25 canine mammary tumours (CMTs), where the stroma associated with the malignancy was specifically considered while histomorphologically analysing the tumours. The majority of the tumours were malignant (96 per cent) and one was identified to be benign. Simple carcinomas made up the majority of tumours, followed by mixed types. Cancer associated stroma was assessed by routine H and E staining and additionally by performing immunohistochemistry technique with anti-cytokeratin antibody to access the relative abundance of neoplastic epithelial cells. Special stains such as Picrosirius red, Masson’s trichrome and Herovici were employed to demonstrate the desmoplastic stromal reaction and varying grades of collagen could be observed in the stroma of different tumours. The extent of fibroplasia was found to be directly proportional to the grade and size of tumour. Thus, results of the present study indicated that the cancer associated stroma significantly in fluence the CMT progression and clinical outcome.

An attempt was made to measure the comparative advantage of dairy farming among different occupational groups of rural Tamil Nadu (540 households and 2500 persons) for its poverty alleviation role. The most commonly used measures of poverty viz., head count index (P 0), poverty gap index (P1) and squared poverty gap (poverty severity) index (P2), the Watts index and average exit time from poverty were calculated. About 59 per cent of the total sample households and close to 65 per cent of sample population were found to stay below poverty line. P1 P2 and W index were observed to be the highest among agricultural labourers and the lowest among dairy farmers. At four per cent of hypothetical income growth rate, the time required to exit out of poverty was estimated to be the least for dairy farmers (4.66 years for buffalo and 4.91 years for cattle), followed by fishermen (5.09 years). Keeping in view of poverty reduction potential of dairy farming, it shall be included in poverty alleviation programmes. 

A pregnant graded Murrah buffalo at eight months of gestation in third parity having bilateral distension of abdomen was presented. The case was diagnosed as hydramnios and treated with dinoprost tromethamine, diethyl stilbesterol, valethamate bromide and dexamethasone. After 76 hours, cervix was dilated fully and trans-cervical amniocentesis was performed and approximately 60-70 litres of amniotic fluid was drained and a dead male fetus with cleft palate was delivered.

A one and half year old heifer was presented with a hard mass hanging from brisket region. The mass was oval shaped, 10 x15 cm in size, pedunculated with the base at the level of carpal joint. Cytological examination revealed melanocytes with the presence of numerous blackish melanin pigments in the cytoplasm. Histopathological examination revealed that the tumor was comprised of heavily pigmented spindle shaped cells, arranged in sheets with a large nuclei and abundant granular black pigment in the cytoplasm. Following surgical removal of the mass, the animal recovered with no recurrence. Based on clinical examination, cytology and histopathological findings, the growth was diagnosed as cutaneous melanoma.

A two year old non descript bitch was presented to the Department of Veterinary Surgery and Radiology, Veterinary Clinical Complex, Rajiv Gandhi Institute of Veterinary Education and Research, Puducherry with a history of an accidentall fall from the first floor of a building to the spiked metal railings of a gate onto the ground level. Physical examination revealed respiratory distress, pain on palpation around thoracic and abdomen region, perforating wound was noticed on the left lateral thorax at the level of 10 costal cartilage and animal was vomiting since then. On radiographic examination, a mild pneumothorax and gas filled air pockets were noticed in the abdomen, suspecting gastric perforation. Haematobiochemical values were within the normal range. Animal was stabilized by oxygen supplementation, IV fluids and analgesics. After stabilization, anaesthesia was achieved by Inj. Diazepam @ 0.5 mg/kg and Inj. Propofol @ 3 mg/kg IV. Exploratory laparotomy was performed to repair the perforating wound. Post operatively, antibiotics and analgesia were administered for 5th days along with fluid therapy. Based on history and clinical examination, the case was diagnosed as gastric perforation due to high rise syndrome and animal made an uneventful recovery.
