ABSTRACT
Javed MT, Usman M, Cagiola M, Irfan
M, Ahmad I., Prevalence of tuberculosis, epidemiology and blood changes in
buffaloes in Pakistan, Onl J Vet Res., 22 (3):216-228, 2018. We describe prevalence of tuberculosis at one farm with 165 buffalo
and another with 163 in Punjab, Pakistan detected by intradermal tuberculin and
purified protein (PPD) tests. Results were assessed at 72 hours as no reaction,
doubtful with a 2-4 mm dermal reaction and definite >4 mm skin or diffuse
inflammatory reaction. Blood was assessed for RBC, WBC, haemoglobin, PCV, ESR
and differential leukocyte count, serum total protein,
albumin and serum globulins. Epidemiological data was collected. We found incidence ranging from 8.48 percent (14/165) to 2.45 percent
(4/163). At both farms we found high levels of doubtful reactions. Reactions in
buffalo over 6 years of age were greater (P < 0.03), higher in weights below
550 kg (P = <0.005), less than 3 partus (P <
0.001) or milk production of 5-7 litres (P < 0.05). Number of buffalo, species and
vicinity to villages had greater effect on prevalence than farm conditions
per se. We found decreased RBC and
ESR (P < 0.05). Serum proteins and globulins were higher in buffaloes with
positive PPD (P < 0.05) and changes in serum total proteins correlated with
globulins (r = 0.918; P = 0.0001) and doubtful reactors (r =
0.691 ; P = 0.0015).
Key words: Tuberculosis, prevalence, epidemiology, blood, Pakistan.
