Aim: A comparative study of Ziehl Neelsen Staining Vs Modified Ziehl Neelsen Staining in the Diagnosis of Osteoarticular Tuberculosis Patients. Materials and Methods: This present study was conducted in our hospital. Entire subjects were signed an informed consent approved by institutional ethical committee RIMS. A total of 200 patients of clinically confirmed osteoarticular tuberculosis (OTB) with age group of 15 years to >75 years were enrolled in this study. All the patients were categorised into two groups (group A&B). Each group had 100 OTB patients. ZN technique was used in group A patients. And MZN technique was used in group B patients. Results: 62% and 63% patients of ZN and MZN staining were males respectively. Among ZN-staining, 37(37%) males and 26(26%) females had smear positive. Among MZN staining group, 40(40%) males and 27(27%) females hadsmear positive. In this present study, smear positivity was seen in 59(59%) ZN- staining and 67(67%) MZN staining OTB patients. Conclusions: This present study concluded that the OTB was more preponderance in middle age male population. Smear positivity for osteoarticular tuberculosis was greater in Modified Ziehl Neelsen staining technique as compared to Ziehl Neelsen. Hence, MZN is a better technique for the diagnosis of osteoarticular tuberculosis.
