Aim: To compare the Modified Ziehl Neelsen Staining and Ziehl Neelsen Staining in the Diagnosis of Osteoarticular Tuberculosis Patients. Materials and Methods: This present study was conducted in Department of Microbiology. Entire subjects were signed an informed consent approved by institutional ethical committee. A total of 100 patients of clinically confirmed osteoarticular tuberculosis (OTB) with age group of 16 years to >70 years were enrolled in this study. All the patients were categorised into two groups (group A&B). Each group had 50 OTB patients. ZN technique was used in group A patients. And MZN technique was used in group B patients. Results: 60% and 64% patients of ZN and MZN staining were males respectively. Among ZN- staining, 18(36%) males and 12(24%) females had smear positive. Among MZN staining group, 20(40%) males and 15(30%) females had smear positive. In this present study, smear positivity was seen in 28(56%) ZN- staining and 35(70%) MZN staining OTB patients. Conclusions: The current investigation found that the occurrence of OTB was higher in the male population of middle age. The Modified Ziehl Neelsen staining approach demonstrated a higher level of positive for osteoarticular TB compared to the Ziehl Neelsen technique. Therefore, MZN is a superior method for diagnosing osteoarticular tuberculosis.
