LYMPHOMA IN DOGS: CLINICOPATHOLOGICAL STUDY OF 331 CASES
Lymphoma was diagnosed in 331 dogs based on cytological examination of clinical samples which accounted to an incidence of 5.88% of the total tumours diagnosed during the period. The highest incidence of lymphoma was recorded in non-descript, Labrador, Dobermann, German shepherd breeds, male dogs, and dogs of age group 5-10 years and 1-5 years in breed, sex and age wise analysis of tumour incidence. In cytological examination, the smears displayed high cellularity with monomorphic population of medium to large sized lymphoblasts exhibiting moderate anisocytosis and anisokaryosis and containing round to spherical to indented nucleus placed centrally or eccentrically. Nucleoli appeared as single large to multiple prominent. The cytoplasm was basophilic and appeared as a narrow marginal rim around the nucleus. Increased number of mitotic figures and lymphoglandular bodies were also seen. Histopathological studies revealed sheets of monomorphic neoplastic lymphocyte cells with round nuclei.
Histiocytoma in Dogs: Cytomorphological and Incidence based study of 162 cases
During the study period, cutaneous histiocytoma was diagnosed in 162 dogs based on pathological evaluation of tumour architecture and cellular morphology. Confirmatory histopathology was performed on selected cases. Demographic variables including breed, age and sex were recorded and analyzed. Histiocytomas diagnosed represented 2.88% of all tumours in the sample population. The tumours were most frequently identified in non descript, Labrador Retriever, and Pug breeds. A male predisposition was noted, and the highest incidence occurred in young dogs, particularly those in the 1–5 year age group followed by dogs less than one year old. Cytologically, tumours exhibited round to spherical neoplastic cells in a discrete pattern, featuring eccentric round, oval, cleaved or indented nuclei, indistinct to prominent multiple nucleoli, and basophilic cytoplasm. Histopathological examination revealed neoplastic cells displaying eccentrically positioned round to bean shaped nuclei, coarse chromatin, prominent nucleoli, and a basophilic cytoplasm, consistent with canine histiocytoma.
Papilloma in Dogs: Cytomorphological Evaluation and Incidence Analysis of 48 Cases
In a study on cytopathological analysis of samples submitted for tumour diagnosis, papilloma was diagnosed in 48 dogs, which accounted to an incidence of 0.85% of the total tumours diagnosed in dogs during the period. Breed, sex and age wise analysis revealed the highest incidence in non descript and Labrador retrievers, with a male predominance and peak occurrence in the 1–5 year age group. Cytologically, the smears showed individual to clustered neoplastic cells of polyhedral to hexagonal shape resembling normal squamous epithelial cells and characterized by pink to purple cytoplasm and round to oval nuclei which were consistent with papilloma. Histopathology demonstrated classic finger like papillary projections of hyperplastic squamous epithelium overlying a fibrovascular connective tissue core, pronounced spinous (prickle) cell layer hyperplasia and hyperkeratosis with round to oval, vesicular nuclei.
MICROSPORUM CANIS DERMATOPHYTOSIS IN PET DOGS AND CATS IN CHENNAI
The study reports the isolation and identification of the dermatophyte Microsporum canis by mycological culture of skin scabs and hair plucks collected from dogs and cats with dermatological complaints and presented to the Centralized Clinical Laboratory, Madras Veterinary College, Chennai-07. M. canis was successfully isolated from 64 canine and 16 feline patients which accounted to population incidence of 4.31% in canine and 72.72% in feline population. Breed-specific analyses in dogs indicated the highest prevalence in Labrador and non-descript breeds, while sex-based analysis showed a predominance in males, and age-wise distribution revealed a peak in the 1-5 year age group. Similarly, in cats, native Indian breeds, females, and individuals aged 1-5 years exhibited the highest incidence. A notable seasonal trend was observed, with the highest occurrence of M. canis recorded during the summer season in both dogs and cats.
HEMATOLOGICAL AND SERUM BIOCHEMICAL PROFILE OF SAHIWAL DAIRY COW DURING TRANSITIONAL PERIOD
The transition period in dairy cows, encompassing the final weeks of pregnancy through the early stages of lactation, is marked by profound metabolic and physiological changes. This study aimed to evaluate the hematological, biochemical, and metabolic profiles of Sahiwal cows during the transition period in comparison to mid-lactation cows. A total of 24 clinically healthy Sahiwal cows were divided into two groups: Group 1 (transition cows, n = 12) and Group 2 (mid-lactation controls, n = 12). A total of 72 Blood samples were collected at multiple time points from 21 days before calving to 21 days postpartum for hematological, lipid, protein, enzyme, and mineral analyses from group 1 and 12 samples were collected from group 2. Results of the present study indicated significant (P ≤ 0.05) hematological alterations, including reduced white blood cell counts and lymphocyte percentages on the day of calving, along with increased platelet counts. Most of the red blood cell indices (Hb, HCT, MCV, MCH), MCHC, remained within normal physiological ranges. Serum lipid parameters like total cholesterol, triglycerides, HDL-C, LDL-C, and VLDL—declined significantly at calving, reflecting a negative energy balance, and did not return to pre-calving levels even 21 days postpartum. Liver enzymes (AST, ALT, ALP) peaked on the day of calving, possibly due to hepatic stress and muscle damage. Significant reductions in calcium, phosphorus, and magnesium levels were also recorded on the day of calving. Protein metabolism was altered, with reduced total protein and globulin concentrations and increased albumin-to-globulin ratios at parturition. Additionally, elevated levels of blood urea nitrogen and creatinine indicated heightened protein catabolism around calving. In conclusion, the study highlights that Sahiwal cows experience marked metabolic stress during the transition period. These findings underscore the importance of closely monitoring blood biochemical parameters to mitigate health risks and optimize management strategies during this transition period.
