BACKGROUND: Glycosylation is one of the most abundant posttranslational polypeptide chain modification in nature. Although carbohydrate modification of protein antigens from many microbial pathogens constitutes important components of B cell epitopes, the role in T cell immunity is not completely understood. There is growing evidence about the importance of these modifications in host bacteria interactions in tuberculosis. It is known, that the sugars present in some Mycobacterium tuberculosis glycoproteins play an important role in both humoral and cellular immune response against the pathogen...

Pelvic and peritoneal tuberculosis may resemble advanced ovarian cancer due to the presence of ascites, complex adnexal masses, peritoneal deposits and raised CA-125 level, especially in peri- and postmenopausal women. Other common features among women with these two conditions are abdominal pain and distension, weight loss and reduced appetite. As the treatment of pelvic-peritoneal tuberculosis is completely different from that of ovarian cancer, it is important to reach a correct diagnosis. Sometimes women with pelvic-peritoneal tuberculosis may be subjected to a laparotomy for suspected ovarian cancer which is likely to increase their morbidity...

Although phthiocerol dimycocerosates (DIM) are major virulence factors of Mycobacterium tuberculosis (Mtb), the causative agent of human tuberculosis, little is known about their mechanism of action. Localized in the outer membrane of mycobacterial pathogens, DIM are predicted to interact with host cell membranes. Interaction with eukaryotic membranes is a property shared with another virulence factor of Mtb, the early secretory antigenic target EsxA (also known as ESAT-6). This small protein, which is secreted by the type VII secretion system ESX-1 (T7SS/ESX-1), is involved in phagosomal rupture and cell death induced by virulent mycobacteria inside host phagocytes...

INTRODUCTION: Non-tuberculous mycobacteria (NTM) can cause disease which can be clinically and radiologically undistinguishable from tuberculosis (TB), posing a diagnostic and therapeutic challenge in high TB settings. We aim to describe the prevalence of NTM isolation and its clinical characteristics in children from rural Mozambique. METHODS: This study was part of a community TB incidence study in children <3 years of age. Gastric aspirate and induced sputum sampling were performed in all presumptive TB cases and processed for smear testing using fluorochrome staining and LED Microscopy, liquid and solid culture, and molecular identification by GenoType® Mycobacterium CM/AS assays...

HIV and tuberculosis infections are known to be associated with vasculopathy including occlusive disease and aneurysm formation. We report a case of 43-year-old male with miliary and central nervous system (CNS) tuberculosis; recently, diagnosed as HIV seropositive, on antiretroviral and antitubercular treatment presenting with painful neck swelling. He was found to have common carotid artery (CCA) pseudoaneurysm that was managed by endovascular stent grafting. HIV vasculopathy-related CCA pseudoaneurysm is a potentially life-threatening rare entity...

This study first presents a mathematical model of TB transmission considering BCG vaccination compartment to investigate the transmission dynamics nowadays. Based on data reported by the National Bureau of Statistics of China, the basic reproduction number is estimated approximately as R0=1.1892. To reach the new End TB goal raised by WHO in 2015, considering the health system in China, we design a mixed vaccination strategy. Theoretical analysis indicates that the infectious population asymptotically tends to zero with the new vaccination strategy which is the combination of constant vaccination and pulse vaccination...

In mycobacteria, it was assumed that efflux pumps only had a marginal role in drug resistance. In recent years, owing to the need to find novel drugs against multidrug-resistant tuberculosis, it has become clear that efflux should not be ignored. Although efflux inhibitors have been very useful for characterizing in vitro the properties of efflux pumps, their usefulness in vivo is limited because of their toxicity. Alternatively, programs aimed at discovering novel drugs for treating tuberculosis should implement strategies to characterize efflux liability of candidate drugs...

Urogenital tuberculosis is the second most frequent form of extrapulmonary tuberculosis. Starting with a pulmonary focus, 2 to 20% of patients develop urogenital tuberculosis through hematogenous spread to the kidneys, prostate, and epididymis; through the descending collecting system to the ureters, bladder, and urethra; and through the ejaculatory ducts to the genital organs. Urogenital tuberculosis occurs at all age ranges, but it is predominant in males in their fourth and fifth decades. It is a serious, insidious disease, generally developing symptoms only at a late stage, which leads to a diagnostic delay with consequent urogenital organ destruction; there are reports of patients with renal failure as their initial clinical presentation...
