Abstract

BASSO, P.C. et al. Ovariosalpingohisterectomy in bitches: comparison of pain, cardiopulmonary, pressure and arterial blood gas analysis of the conventional approaches, by NOTES hybrid and NOTES pure. Arq. Bras. Med. Vet. Zootec. [online]. 2014, vol.66, n.5, pp.1329-1338. ISSN 0102-0935.  http://dx.doi.org/10.1590/1678-6671.

The aim of the present study was to perform bacteriological and molecular methods for identification of Mycobacterium bovisin lesions derived from bovine carcasses detected during routine post-mortem examination in officially inspected slaughterhouses. We checked the slaughter and inspection of 825,394 bovines, health upon ante-mortem examination, by the official service in 10 slaughterhouses of Bahia state from April, 2009 to April 2012. Lesions suggestive of tuberculosis were collected from 180 bovines and further evaluated by bacteriology and multiplex PCR. The majority of lesions were located in the respiratory tract lymph nodes and 71% were from male bovines up to 32 months old. 13.9% of samples presented small, granular and creamy-yellowish colonies after being cultured in Stonebrink-Leslie with an average growth time of 34 days. All smears from the isolated samples were Acid Fast Bacilli (AFB) and among them 56% were identified by mPCR as M. bovis. Thus, the association between post-mortem examination, culture and multiplex PCR allowed the bacillus identification in a reduced time and in regions of low prevalence, pointing out its importance for bovine tuberculosis detection and as a supportive tool for the tuberculosis control and eradication program.
