The hand and wrist are rare sites for tuberculosis (TB) and account for < 1% of all skeletal TB. Though rare, TB of the wrist is a cause of major morbidity. A common feature in the available reports on wrist TB is a delay in diagnosis causing residual stiffness and pain after treatment. Although TB of the wrist has a varied presentation, the majority of lesions respond to conservative treatment. We report a 12-year-old girl who presented with wrist swelling, having intercarpal, carpometacarpal, and radiocarpal joint involvement which turned out to be tuberculous and it healed with residual deformity...

Most infections related to peritoneal dialysis (PD) are caused by common bacteria, and non-tuberculous mycobacteria are rare. The clinical characteristics and prognosis of PD patients with non-tuberculous mycobacterial infections were investigated at our hospital. Non-tuberculous mycobacteria were detected in 11 patients (exit-site infection, tunnel infection, and peritonitis in 3, 5, and 3 patients, respectively). Mycobacterium fortuitum , Mycobacterium chelonae , and Mycobacterium abscessus were identified in 4, 2, and 2 patients, respectively...

OBJECTIVE: To report atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) levels in patients with tuberculous meningitis (TBM) and acute encephalitis syndrome (AES), and evaluate their relationship with hyponatraemia. METHODS: Consecutive patients with TBM and AES were included in the study. Hyponatraemia was categorised as cerebral salt wasting (CSW), syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and a miscellaneous group based on clinical and laboratory criteria...

BACKGROUND: The well-documented association between underweight and increased incidence of active tuberculosis (TB) has not been extended to incidence or prevalence of latent tuberculous infection (LTBI). DESIGN: After identifying studies that reported a categorical measure of body mass index (BMI) and used the tuberculin skin test (TST) or QuantiFERON®-TB Gold In-Tube (QFT) to measure LTBI, a maximum likelihood random-effects model was used to examine the pooled association between LTBI and low BMI (<18...

Mycobacterium tuberculosis has a wide variety of presentations. A rare occurrence is gastrointestinal tuberculosis. It may occur anywhere along the alimentary canal but usually occurs in the ileocecum with rare involvement of the appendix.

Tuberculous meningitis (TBM) is a severe form of tuberculosis with a high mortality rate. The factors associated with TBM pathogenesis are still unclear. Using comparative whole-genome sequence analysis we compared Mycobacterium tuberculosis (Mtb) isolates from cerebrospinal fluid of TBM cases (n = 73) with those from sputum of pulmonary tuberculosis (PulTB) patients (n = 220) from Thailand. The aim of this study was to seek genetic variants of Mtb associated with TBM. Regardless of Mtb lineage, we found 242 variants that were common to all TBM isolates...

AIMS: Mycobacterium tuberculosis and non-tuberculous mycobacteria (NTM) are clinically different, and the rapid detection and differentiation of M. tuberculosis complex (MTBC) and NTM is crucial for patient management and infection control. Given the slow growth of most pathogenic mycobacteria, nucleic acid amplification assays are excellent tools for direct identification of mycobacteria in clinical specimens. Recently, a multiplex real-time PCR assay was developed that can directly detect 20 mycobacterial species in clinical specimens...

Accurate diagnosis of tuberculosis in cattle may be compromised in areas where there are high rates of exposure to environmental/non-tuberculous mycobacteria (NTM). This cross reaction of immune responses to Mycobacterium bovis antigens shared with NTMs can result in reduced specificity of commonly used diagnostic tests including tuberculin skin tests and the interferon gamma assay (IFN-ɣ). In this study we assessed the cross-reactive immune responses of M. bovis (infected) and NTM exposed animals to M. bovis and M...

BACKGROUND: Fitz-Hugh-Curtis syndrome or acute perihepatitis is considered a rare complication of pelvic inflammatory disease, mostly associated with chlamydial or gonococcal salpingitis. Peritoneal tuberculosis is a rare site of extra-pulmonary infection caused by Mycobacterium tuberculosis. Infection usually occurs after reactivation of latent tuberculous foci in the peritoneum and more seldom after contiguous spread from tuberculous salpingitis. CASE PRESENTATION: We describe a case of a 21-year old female of Somalian origin diagnosed with Fitz-Hugh Curtis syndrome associated with tuberculous salpingitis and peritonitis, presenting with new onset ascites...

BACKGROUND: Species of Mycobacteriaceae cause serious zoonotic diseases in mammals, for example tuberculosis in humans, dogs, parrots, and elephants (caused by Mycobacterium tuberculosis) and in ruminants and humans (caused by M. bovis and M. caprae). Pulmonary diseases, lymphadenitis, skin diseases, and disseminated diseases can be caused by non-tuberculous mycobacteria (NTM). Diagnosis and differentiation among Mycobacterium species are currently done by culture isolation. The established diagnostic protocols comprise several steps that allow species identification...

Mycobacterium avium subsp. hominissuis (MAH) is an important zoonotic pathogen with raising global health concerns. In humans, MAH is one of the most widespread non-tuberculous mycobacterial species responsible for lung disease. In animals, MAH is frequently isolated from pigs; however, it is also an opportunistic pathogen for other mammals including cattle. To elucidate the genetic diversity of MAH in cattle, a molecular characterization of isolates ( n  = 26) derived from lymph nodes was performed. Fourteen isolates originated from slaughtered cattle with visible altered lymph nodes at meat inspection, whereas 12 isolates were from lymph nodes without any gross pathological changes of healthy slaughtered cattle...

Mycobacterium marinum is a non-tuberculous pathogen of poikilothermic fish and an opportunistic human pathogen. Like tuberculous mycobacteria, the M. marinum M strain requires the ESX-1 (ESAT-6 System 1) secretion system for virulence in host cells. EsxB and EsxA, two major virulence factors exported by the ESX-1 system, are encoded by the esxBA genes within the ESX-1 locus. Deletion of the esxBA genes abrogates ESX-1 export and attenuates M. marinum in ex vivo and in vivo models of infection. Interestingly, there are several duplications of the esxB and esxA genes ( esxB_1, esxB_2, esxA_1 , esxA_2, and esxA_3 ) in the M...

Lung disease in cystic fibrosis (CF) is characterized by the progressive colonization of the respiratory tract by different bacteria, which develop polymicrobial biofilms. In the past decades, there has been an increase in the number of CF patients infected with Non-Tuberculous Mycobacteria (NTM). Although Mycobacterium abscessus is the main NTM isolated globally, little is known about M. abscessus multispecies biofilm formation. In the present study we developed an in vitro model to study the phenotypic characteristics of biofilms formed by M...

Mycobacterium neoaurum is a rapidly growing non-tuberculous mycobacterium which is ubiquitous in nature. While it can cause line related infections in immunocompromised host, case reports of urinary tract infections, cutaneous infections, pulmonary infections, and meningoencephalitis have also been reported. We report the first case of Mycobacterium neoaurum line related bacteremia with concomitant pulmonary involvement. Our patient responded well to a nine week course of antimicrobials after removal of infected central line...

Tuberculosis (TB) is a worldwide public health problem; however, primary tuberculous osteomyelitis involving the mandible is extremely rare. Here, we report a 14-year-old boy who presented with a recurrent, generalized swelling of the cheek in the right side, mimicking parotitis. Fine needle aspiration cytology (FNAC) from the swelling was inconclusive. Contrast-enhanced computed tomography (CECT) of the head and neck revealed an osteolytic lesion of the mandible with a surrounding abscess. An intraoral incisional biopsy of the tissue showed a granulomatous lesion...

The aim of this study was to determine whether twinkling artifact (TA) detected on color Doppler ultrasonography can effectively determine the presence of pleural calcification compared with computed tomography (CT) and differentiate tuberculous pleuritis (TP) and cancerous pleuritis (CP). One hundred six cases of TP and 26 cases of CP were scanned using gray-scale ultrasonography (GSU) and TA to determine the presence of pleural calcification. With CT as the reference standard, 63.3% and 79.6% of patients with pleural calcification were identified with GSU and TA, respectively...
