Bovine tuberculosis (bTB) is a chronic illness in animals, especially in cattle, leading to loss in the productivity and signifies a crucial public health risk. Regardless of the zoonotic threat and significant economic costs associated with the disease, precise estimates of bTB prevalence are deficient in many countries, including India, where national control programs are yet to be instigated. The true burden of the disease remains unknown due to lack of routine surveillance data from most of the developing countries. India is progressing well towards attaining the End TB goal, yet bTB continues to remain largely hidden. Moreover, the paucity of literature on bTB in India might lead to undue complacency and hence has to be scrupulously guarded and prevented from gaining any misconceptions in the minds of the common people. Preventing and controlling bTB at the animal interface is pivotal to evade transmission to human, increase food safety and guard the livelihood of the people. To attain this goal, implementation of strategies based on international norms and a multi-sectoral approach will empower enhanced surveillance and diagnosis of disease in animals and subsequently reduce the risk for humans. As an initiative, we step forward to address this review which briefly summarizes the available data in the literature from early 20th century to date to assess the status of bTB in India. We have discussed in detail, the epidemiology, transmission and diagnosis pertaining to bTB. The review also focuses on the interconnection between the health of people and animal, discuss the preventions and control strategies and recommend the use of vaccination in cattle to reduce the spread of infection among other animals and humans. Implementing One Health approach in India, which recognizes the interdependence of the health of people and animals will help the nation in the fight against TB. Multidrug-resistant tuberculosis (MDR-TB) is one of the causes of morbidity and mortality, among tuberculosis (TB) patients in Malaysia. The purpose of this study was to determine the contributing risk factors to the prevalence of (MDR-TB). Based on systematic review of the literatures, the prevalence of (MDR-TB) and associated risk factors in Malaysia were studied. A comprehensive search of Scopus, Science direct, PubMed, DOAJ, CINAHL Plus, MyJournal, BIREME, BMC Public Health, Medline, CAB, and WoS databases were done among the articles published from 31st January 2009 to 31st December 2018, by using medical subject heading (MeSH) key terms. In conducting this study, a total of 121 papers were reviewed and 23 research papers were chosen, because, they met the specific inclusion criteria. In this study, gender, age, marital status, ethnicity, homeless status, living in urban area and history of imprisonment were evaluated as demographic factors, while educational level and employment were evaluated as socioeconomic factors. SM-102 order Smoking, diabetes mellitus, drug abuse and alcohol consumption were evaluated as behavioral and co-morbidities factors. All the studies chosen as eligible to be included in this study were found to be significantly associated with the risk factors for the prevalence of (MDR-TB). It was also discovered that, lack of adequate knowledge among the community and (TB) patients might increase the progression of (MDR-TB) infection in Malaysia. Thus, carried out a systematic review provided a comprehensive assessment of the (MDR-TB) which might be useful for policy makers, health experts and researchers to implement appropriate strategies for (TB) infected population in Malaysia. Pulmonary tuberculosis is associated with higher plasma levels of antimicrobial peptides (AMPs) and lower granulysin levels. However, the association of AMPs with tuberculous lymphadenitis (TBL) is not well studied. Hence, we measured the plasma levels of human beta defensin-2 (HBD2), granulysin, human neutrophil peptides 1-3 (HNP1-3) and cathelicidin (LL37) in TBL compared to latent tuberculosis (LTB) and healthy controls (HC) and in TBL individuals upon completion of anti-tuberculosis treatment (ATT). We examined the association of AMPs with TBL lymph node culture grade or lymph node involvement. Finally, the discriminatory potential of these proteins was assessed using receiver operating characteristic (ROC) analysis. TBL individuals display significantly diminished circulating levels of AMPs (granulysin and HNP1-3) but not HBD-2 and LL-37 in comparison to LTB and HCs. Similarly, after ATT, both HBD-2 and HNP1-3 were significantly elevated and LL-37 was significantly reduced in TBL individuals. Granulysin and HNP1-3 discriminates TBL from LTB and HC individuals upon ROC analysis. AMPs did not exhibit significant correlation either with lymph node culture grades or lymph node involvement. Overall, TBL individuals show decreased AMPs and their reversal after ATT suggesting their association with underlying immune alteration in this poorly studied form of TB disease. In this study, we analyzed the M. tuberculosis complex (MTBc) population structure among multidrug-resistant TB (MDR-TB) patients in Niger and tested whether the Cameroon family displayed a slower response to MDR-TB treatment. We genotyped baseline clinical isolates that had been collected from pulmonary MDR-TB patients recruited consecutively between 2008 and 2016 in Niger. Spoligotyping was used to analyze the genetic diversity of mycobacterial lineages, and Kaplan Meier's analysis to compare treatment outcomes. A total of 222 MTBc isolates were genotyped; 204 (91,9%) were identified as the Euro-American L4 lineage, with the Ghana family (106, 47,4%) and the Cameroon family (63, 28,4%) being predominant. Patients infected by Cameroon family isolates 61(96,8%) showed faster conversion (log-rank p 0.05). Our findings show that MDR-TB in Niger is caused by major spoligotypes of the Euro-American L4; with more rapid smear and culture conversion in patients infected with the Cameroon family. These first insights may alert clinicians that slow conversion may be associated with the type of infecting strain.
