Veterinary Pathology

About Department

The Department of Veterinary Pathology came into being as an independent existence in June, 1965. In the year 1978-79, disease investigation part was separated and formed a part of the newly created Department of Veterinary Public Health & Epidemiology. Following are the objectives and activities of the Department.
  • Provides a significant role in the diagnosis and etio-pathological studies of important diseases of different species of animals and poultry prevailing in Haryana state
  • Diagnosis, prevention and control of emerging/ re-emerging diseases of livestock and poultry
    • Hematological and Biochemical testing
    • Post-mortem examination
    • Histopathological and Biopsy examination
  • Preservation of gross specimens of various diseases in museum for education and awareness
  • Public advisory service regarding diseases of zoonotic importance- Avian influenza, Swine flu, Rabies etc.
  • Development of quality human resource by providing education and imparting training
    • Education- BVSc & AH, MVSc, PhD
    • Continuing education of field veterinarians
    • Farmer advisement and counseling
  • Provides expert guidance for the disease diagnosis and its prevention and control to Livestock/Poultry farmers in form of Farm Darshan, Kisan Melas etc.

Major Achievements

Brucellosis: Diagnostic tests like dot enzyme linked immunosorbent assay, counter immunoelectrophoresis technique, coagglutination assay have been developed for the serodiagnosis of brucellosis.

Listeriosis: Listeria ivanovii has been isolated for the first time in India, from cases of abortion in sheep.

Degnala disease: Degnala disease in buffaloes and cattle has been found to be associated with feeding of fungus-infested (Fusarium equiseti) rice straw. On the basis of these findings, preventive measures have been suggested to the farmers and field veterinarians.

Horn cancer: Bovine horn cancer, a squamous cell carcinoma of the horn core epithelium, has been found to metastasize to various lymph nodes and internal organs like lungs, heart and meninges of brain. Treatment of the animals with a saline phenol extract of the cancer tissue and levamisole gave encouraging results in the restoration of the depressed CMI status and help in recovery in early cases.

Hydropericardium syndrome: Litchi disease (Hydropericardium syndrome), a highly contagious disease of broiler chicks, was experimentally reproduced and studied. A formalized liver suspension can be used for its prevention under field conditions. Significant research has been carried out in the department to study the effect of various parameters on the pathology and pathogenesis of the disease. These findings include :
  • Supplementation of Vitamin E @ 150 mg/kg of feed, Zinc sulphate @ 700 ppm or Ascorbic acid @ 330 ppm reduced the severity as well as recovery period of HPS infection suggesting their protective role in limiting the pathology and pathogenesis of HPS infection in broiler chickens. Secondly, Vitamin E supplementation enhanced the Cell mediated immune response suggesting its immunomodulatory activity.
  • Ochratoxin-A @ 1.5 ppm in feed causes the immuno-suppression and an increased severity of Hydropericardium syndrome (HPS) in broiler chicks.
  • Studies on administration of Cyclosporin A and Cyclophosphamide (important T- Cell suppressors) in experimentally affected HPS broiler chickens revealed that the T-Cell and B-Cell plays a significant role in pathogenesis and pathology of disease.
  • The effect of Infectious bursal disease (IBD) vaccine and levamisole was also studied on the pathology and pathogenesis of experimentally induced HPS and it was found that severity of HPS was increased in IBD vaccinated chickens whereas there was a therapeutic effect of levamisole on the basis of clinical signs, mortality and patho-biochemical studies.
  • A comparative study to investigate the efficacy of oil emulsion and formalin killed vaccines (inactivated vaccines) against hydropericardium syndrome in broiler chickens revealed that formalin killed vaccine is more effective than the oil adjuvant vaccine.
Etio-pathological studies on bovine mortality :
  • Etio-pathological studies on bovine calf mortality revealed that main cause of death of bovine calves is bacterial infections mainly Escherichia coli associated with pneumonia and enteritis and hepatitis.
  • Various serotypes of Escherichia coli were isolated and one of the serogroup O114 has significance from public health point of view.
  • In vitro drug sensitivity and resistance studies revealed that Escherichia coli isolates were most sensitive to combination of ceftriaxone and sulbactum followed by gentamicin and most resistant against oxytetracycline and streptomycin.
  • Plasmid profiling of Escherichia coli isolates revealed that out of 19 Escherichia coli isolates, 18 Escherichia coli isolates possessed plasmids of molecular weights ranged from 4 to 20 Kb. The serotypes which were resistant to one or more than four antibiotics were found to possess plasmid of high molecular weight i.e. 20 Kb.
Etio-pathological studies on poultry mortality: Etio-pathological studies on poultry mortality showed that gastrointestinal disorders are the main cause of poultry mortality. Severity of gross and microscopic lesions in cases of Salmonella spp. and Escherichia coli infections indicate that both are still major pathogens of poultry. Majority of isolates were sensitive to ceftrioxone, cefuroxime, amoxyclav, chloramphenicol, gentamycin and amoxycillin. So, these drugs may be used as the drug of choice for treating clinical cases of these bacterial infections.

Studies on Pasteurella multocida: In the experimental study of pathogenicity and preliminary vaccine trial in mice on field Pasteurella multocida isolated from post mortem cases it was observed that Saponin administration @200 µg/mice caused death and can not be advised as an adjuvant in the mice with killed Pasteurella multocida serotype B.

Studies on deficiency diseases :
  • Zinc deficiency which is quite common in Haryana state has been found to cause immuno-suppression (both cellular and humoral) and increases the severity of Salmonella infection and foot and mouth disease in guinea-pigs.
  • Outbreaks of rheumatism-like syndrome in buffaloes in different parts of Haryana were successfully investigated and were found to be associated with phosphorus deficiency. The affected animals responded favourably to phosphorus.
Immuno-pathological studies on herbal immunomodulators on various poultry diseases :
  • Supplementation of Ocimum sanctum (Tulsi) leaves powder @ 5g/kg feed was found to have protective effect and immune modulatory action in experimental Salmonella gallinarum and HPS infections in broiler chickens.
  • Supplementation of Neem leaf extract (10%) reduced the severity of HPS and Salmonella gallinarum infection and enhanced the cell mediated immune response, suggesting the protective role of Tulsi and Neem leaves in limiting the pathology and pathogenesis of infections in broiler chickens.
