Salient achievements pertaining to disease diagnosis during the period under ADMAS

Sero-prevalence studies

A total of 1538 serum samples were collected from cattle from different parts of Meghalaya for detection of various diseases by serological tests. Sero-prevalence study for Infectious Bovine Rhinotracheitis (IBR), Brucellosis and Leptospirosis from cattle of Meghalaya was carried out using ELISA kit for the period of 2001-09. Similarly, sero-prevalence study for the parasitic diseases like Hemonchus spp. Oesophagostomum spp. and Trichuris spp. in cattle of Meghalaya were also carried out. . Out of these 1538 serum samples tested, 115/588 (19.56%) samples for Infectious Bovine Rhinotracheitis (IBR), 123/971 (12.67%) for Brucellosis, 12/18 (66.6%) for Leptospirosis, 30/258 (11.62%) for Hemonchus spp., 39/258 (15.11%) for Oesophagostomum spp. and 58/258 (22.48%) for Trichuris spp. were found to be positive by ELISA.

Additionally, 621 serum samples were also collected from cattle from different parts of the NEH region (Assam-92, Manipur-140, Mizoram-359, Arunachal Pradesh-4 and Sikkim-26) which were tested for IBR and Brucellosis using ELISA kit and the detail sample collection and results are depicted in Table 4. Overall, 152/528 (28.79%) and 100/485 (20.62%) serum samples of cattle were positive for IBR and brucellosis, respectively.

Serum samples (200) from mithun were also collected during the period under report from NRC, Mithun farm, Nagaland for the detection of sero-prevalence for IBR and brucellosis. All the 200 serum samples were tested for IBR and brucellosis where, 18 (9.0%), and 26 (13.0%) samples were found to be positive for the respective diseases.
Besides these, 64 serum samples were also collected from buffaloes from different parts of the NEH region. These samples were tested for IBR and Brucellosis using ELISA kit Overall, 0/8 (0.0%) and 7/64 (10.94%) serum samples of buffaloes were positive for IBR and brucellosis, respectively.

Sheep (23) and goat (121) serum samples were collected during the period under report from Meghalaya for the detection of sero-prevalence rate of brucellosis and toxoplasmosis by using ELISA kit. Only 2 (8.69%) samples from sheep were positive for brucellosis, while 3/62 (4.8%) and 2/21 (9.52%) serum samples of goat were positive for brucellosis and toxoplasmosis, respectively .

One hundred and sixty seven serum samples were collected from Swine of Meghalaya for detection of sero-prevalence rate of Classical Swine Fever (CSF) and brucellosis . Total of 14/119 (11.76%) samples for CSF and none for brucellosis were found to be positive.

Also, 110 serum samples from poultry from Meghalaya were collected and tested for Leechi disease and Infectious Bursal Disease (IBD), where 1/110 (0.9%) serum samples for Leechi disease & 20/110 (18.9%) for IBD were found positive.
