Clinical and pathological insights into Johne's disease in buffaloes.

Alternative diagnostic tools and interesting epidemiological assumptions were associated with an outbreak of Johne's disease. In a buffalo herd infected with paratuberculosis, seven clinically affected animals and 21 animals with anti-Mycobacterium avium ELISA reactions were identified. Total herd included 203 buffaloes. Most lesions were comparable to those described in buffaloes and cattle affected by Johne's disease. Water buffalo behaviors such as communal nursing and allosuckling may be additional risk factors for this disease. Detection of positive Ziehl-Neelsen staining and anti-M. avium immunolabeling in rectal biopsies from one buffalo with paratuberculosis are highlighted as auxiliary diagnostic tools for Johne's disease in live animals.

Evaluation of chlorhexidine effects on periodontium healing after gingivoplasty surgery

Introduction and objective: The aim of this study was to evaluate, in vivo, the effect of 0.12% chlorhexidine on the healing of gingival tissues undergoing gingivoplasty. Material and methods: The clinical assessment was checked by plaque and gingival indexes and by periodontal probing depth. After the basic procedures of periodontal therapy, 12 patients underwent gingivoplasty technique. All patients used chlorhexidine mouthrinsing for 7 or 14 days postoperatively. Results: Postoperative indexes measured at 14 and 30 days after surgery showed significant improvements in all parameters. Conclusion: The use of chlorhexidine resulted in statistically significant responses, reducing the plaque and gingival indexes of tissues undergoing gingivoplasty surgery. There is no need of extending chlorhexidine for more than 7 days.
