BACKGROUND: Tuberculosis (TB) is a major health problem, and accurate and rapid diagnosis of multidrug-resistant (MDR) and extended drug-resistant (XDR) TB is important for appropriate treatment. In this study, performances of solid and liquid culture methods were compared with respect to MDR- and XDR-TB isolate recovery and drug susceptibility testing. METHODS: Sputum specimens from 304 patients were stained with Ziehl-Neelsen method. Mycobacterium tuberculosis (Mtb) isolates were tested for recovery on Löwenstein-Jensen (LJ) medium and the BacT Alert 3D system. For drug susceptibility testing of Mtb, isolates were evaluated on M-KIT plates and the BacT Alert 3D system. RESULTS: The recovery rates were 94.9% (206/217) and 98.2% (213/217) for LJ medium and the BacT Alert 3D system, respectively (kappa coefficient, 0.884). The rate of drug resistance was 13.4% for at least one or more drugs, 6.0% for MDR-TB and 2.3% for XDR-TB. M-KIT plate and BacT 3D Alert 3D system were comparable in drug susceptibility testing for isoniazid (97.7%; kappa coefficient, 0.905) and rifampin (98.6%; kappa coefficient, 0.907). Antibiotic resistance was observed using M-KIT plates for 24 of the total 29 Mtb isolates (82.8%). CONCLUSION: The liquid culture system showed greater reduction in the culture period, as compared with LJ medium; however, drug susceptibility testing using M-KIT plates was advantageous for simultaneous testing against multiple drug targets.

Mycobacterium (M.) bovis, a bacterium in the M. tuberculosis complex, is a causative agent of bovine tuberculosis, a contagious disease of animals. Mycobacterial culture is the gold standard for diagnosing bovine tuberculosis, but this technique is laborious and time-consuming. In the present study, performance of the SD Bioline TB Ag MPT4 Rapid test, an immunochromatographic assay, was evaluated using reference bacterial strains and M. bovis field isolates collected from animals. The SD MPT64 Rapid test produced positive results for 95.5% (63/66) of the M. bovis isolates from cattle and 97.9% (46/47) of the isolates from deer. Additionally, the test had a sensitivity of 96.5% (95% CI, 91.2-99.0), specificity of 100% (95% CI, 96.7-100.0), positive predictive value of 100% (95% CI, 96.7-100.0), and negative predictive value of 92.9% (95% CI, 82.7-98.0) for M. bovis isolates. In conclusion, the SD MPT64 Rapid test is simple to use and may be useful for quickly confirming the presence of M. bovis in animals.

Mycobacterium (M.) bovis causes tuberculosis and has a broad host range, including humans, livestock, and wild animals. M. bovis infection of wild boar has been reported in several European countries. We report here the first case of M. bovis infection in a domesticated wild sow in Korea. Granulomatous and necrotizing lesions with small numbers of acid-fast bacilli were observed in nodules of the lung of wild sow. Furthermore, the M. bovis isolate from the wild sow had spoligotype SB0140 and a novel MIRU-VNTR allelic profile, which is not found in cattle and deer in Korea.

INTRODUCTION: In the Philippines, several health policies have been tailored to promote breastfeeding. Statistics show that despite efforts, breastfeeding prevalence remains low. This study aims to determine the demographics and associated barriers and enablers of breastfeeding among mothers living in Metro Manila. METHODS: The study used a cross-sectional analytical design through an online self-administered questionnaire on barriers and enablers answered by mothers between 15-49 years old, residing in Metro Manila. RESULTS: A total of 761 responses were included in the fnal analysis. Only age was found to be signifcantly associated with the practice of breastfeeding. Barriers identifed were 1) seeing breastfeeding as timeconsuming, 2) development of sore or tender nipples, 3) previously failed breastfeeding attempts, 4) poor latching on, and 5) not enough breastmilk production. Enablers identifed were 1) seeing the practice as a good way to bond with the child, 2) presence of breastfeeding areas at work or school, 3) previous success in breastfeeding experience, 4) support from hospital staff or midwives, 5) having knowledge on whom to contact when challenged with breastfeeding, and 6) knowledge of the benefts of breastfeeding on infant and maternal health. CONCLUSION Barriers and enablers towards breastfeeding may be target points for improvement of interventions aiming to increase prevalence of breastfeeding among mothers in Metro Manila.
