Counting Pyrazinamide in Regimens for Multidrug-Resistant Tuberculosis [PDF]
Abstract Rationale For treatment of multidrug-resistant tuberculosis, World Health Organization (WHO) guidelines recommend four likely effective drugs plus pyrazinamide (PZA), irrespective of the likely effectiveness of PZA in an individual patient.

Mutations Associated with Pyrazinamide Resistance in the Clinical Isolates of Mycobacterium tuberculosis [PDF]
Pyrazinamide is one of the four first line drugs for treatment of tuberculosis. It has been widely accepted, that pyrazinamide (PZA) resistance in Mycobacterium tuberculosis is correlated with mutations in the pncA gene.

Molecular characterization of pyrazinamide resistance in Mycobacterium tuberculosis
Tuberculosis (TB) is a highly infectious disease that causes the second highest mortality rate in human worldwide. The emergence of multi-drug resistance tuberculosis (MDR-TB) leads to a major public health problem in controlling TB-caused mortality. Pyrazinamide (PZA) is an important first-line drug in the treatment of MDR-TB.

Pyrazinamide resistance in Mycobacterium tuberculosis fails to bite? [PDF]
In contrast to most other antimycobacterial drugs where--particularly in multidrug-resistant (MDR) strains--a limited number of resistance mutations dominate, pyrazinamide (PZA) resistance associated mutations remain highly diverse with limited clustering.

Impact of pyrazinamide resistance on multidrug-resistant tuberculosis in Karakalpakstan, Uzbekistan [PDF]
The World Health Organization (WHO) recommends the inclusion of pyrazinamide (PZA) in treatment regimens for multidrug-resistant tuberculosis (MDR-TB) unless resistance has been confirmed.To investigate the association between PZA susceptibility and MDR-TB treatment outcome among patients treated with a PZA-containing regimen and whether the duration ...

Analysis of rpoB and pncA mutations in the published literature: an insight into the role of oxidative stress in Mycobacterium tuberculosis evolution? [PDF]
Introduction: It is perceived wisdom that within the host macrophage, Mycobacterium tuberculosis frequently encounters oxidative stress. Exposure of bacteria to reactive oxygen intermediates can have a mutagenic effect on the DNA.

Programmatically selected multidrug-resistant strains drive the emergence of extensively drug-resistant tuberculosis in South Africa [PDF]
South Africa shows one of the highest global burdens of multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis (TB). Since 2002, MDR-TB in South Africa has been treated by a standardized combination therapy, which until 2010 included

Activity of n-propyl pyrazinoate against pyrazinamide-resistant Mycobacterium tuberculosis: investigations into mechanism of action of and mechanism of resistance to pyrazinamide [PDF]
The mechanism of action of pyrazinamide (PZA) is not known. One hypothesis is that PZA functions as a prodrug of pyrazinoic acid. Susceptibility to PZA correlates with amidase activity of the Mycobacterium tuberculosis isolate in question. PZA-resistant isolates retain susceptibility in vitro to pyrazinoic acid and n-propyl pyrazinoate.
