Mycobacterium tuberculosis complex is the cause of tuberculosis (TB) in humans and other animals. Specifically, Mycobacterium bovis (M. bovis) and Mycobacterium tuberculosis (M. tuberculosis) are highly pathogenic mycobacteria that may infect different animal species and are the sources of TB in humans. The objective of this paper was to review the epidemiology of M. bovis and M. tuberculosis in animals. The review also highlighted the transmission dynamics of M. bovis and M. tuberculosis in humans and animals and control challenges of zoonotic TB in Ethiopia...

Granulomatous peritonitis represents a rare postoperative complication that should be considered as important differential diagnosis in all patients who present to the hospital with abdominal pain, abdominal tenderness, and fever after abdominal surgery. Clinical distinction from abdominal tuberculosis remains a diagnostic challenge and requires thorough histopathological and microbiological examination.

Recent studies have demonstrated that circular RNAs (circRNAs) could serve as potential molecular markers for disease diagnosis; however, little is known about their diagnostic value in active tuberculosis (TB). This study first performed a microarray screening of circRNA changes in plasma samples from 3 patients with active pulmonary TB and 3 healthy controls. Then, candidate circRNAs were selected for validation on a quantitative real-time PCR system. Of the 61 differentially expressed circRNAs recorded, 43 and 18 were upregulated and downregulated in the TB group, respectively...

BACKGROUND: We previously reported increased unstimulated blood levels of interferon-gamma in persons with latent tuberculosis infection (LTBI) in the United States, suggesting enhanced immune activation in LTBI. To investigate this further in a TB-endemic setting, we assessed interferon-gamma levels in persons with and without LTBI in Peru. METHODS: We analyzed data from patients with and without a recent type 1 (spontaneous) acute myocardial infarction (AMI) who were enrolled from two public hospital networks in Lima, Peru, and underwent LTBI testing using the QuantiFERON® TB Gold In-tube (QFT) assay...

Infectious diseases can present similar to ovarian cancer and occur concomitantly with ovarian pathology. With increased worldwide travel and migration of populations, infections endemic to developing countries can emerge in the United States. We present 2 cases of infectious diseases mimicking ovarian carcinomatosis. Two Filipino women presented with abdominal distension and had evaluations suggestive of advanced gynecologic malignancy. The first patient underwent surgery and was found to have peritoneal tuberculosis...

Next Generation Sequencing (NGS) technologies using massively parallel processing to interrogate pathogen genomes in days are revolutionising the clinical microbiology practice [1]. Whole genome sequencing (WGS) offers unprecedented resolution for genotyping, outbreak investigation and determination of known sequence variants involved in antimicrobial resistance (AMR), which deep sequencing of selected genomic regions (targeted NGS, tNGS) can further illuminate. WGS-based approach has been proposed for surveillance of bacterial pathogens included in the "priority list" by the World Health Organization (WHO) [2]...

In this study, the electropolymerization of 4-hydroxyphenylacetic acid (4-HPA) over graphite electrodes (GE) was optimized, aiming its application as a functionalized electrochemical platform for oligonucleotides immobilization. It was investigated for the number of potential cycles and the scan rate influence on the monomer electropolymerization by using cyclic voltammetry technique. It was observed that the polymeric film showed a redox response in the region of +0.53/+0.38 V and the increase in the number of cycles produces more electroactive platforms because of the better electrode coverage...

High-temperature requirement A (HtrA) proteins, which are members of the heat-shock-induced serine protease family, are involved in extracytoplasmic protein quality control and bacterial survival strategies under stress conditions, and are associated with the virulence of several pathogens; they are therefore major drug targets. Mycobacterium tuberculosis possesses three putative HtrAs: HtrA1 (Rv1223), HtrA2 (Rv0983) and HtrA3 (Rv0125). Each has a cytoplasmic region, a transmembrane helix and a periplasmic region...

Diaphyseal tuberculosis (TB) is a rare case of the skeletal TB. The following report documents the case of a 52-year-old Moroccan woman with a swelling over the right forearm followed by pulmonary TB under treatment for 3 months. The radiographs of the forearm show a lytic image located at the radius mid-diaphysis. The histopathology confirmed the diagnosis. The patient received surgical drainage with trepanation of the bone. The antibacillary chemotherapy was administered for 6 months. It is, therefore, indispensable to bear in mind the possibility of such atypical presentations of TB when making a rapid and pertinent diagnosis and prescribing the appropriate treatment...

Chyluria is described as passage of chyle in the urine. It results from the formation of lymphaticorenal fistulae due to various etiologies. The most common implicated cause is filariasis especially in endemic areas. Other uncommon causes include thoracic duct trauma or anatomical abnormalities, pregnancy, malignancy, and tuberculosis. Although tuberculosis has been included as a cause, there are only a few case reports suggesting it as an etiology. Tuberculosis can present in various ways. However, chyluria as initial presentation of tuberculosis has never been reported in the literature...

Background: Tuberculosis is a major global health problem. Tuberculous lymphadenopathy is a most common form of extrapulmonary tuberculosis (EPTB), constitutes 35% of all cases of EPTB. Due to the paucibacillary nature of specimens, smear microscopy and culture offer low sensitivity. Methods: The aim of the present study was to find the clinicodemographic profiles and comparing the performance of Xpert MTB/RIF, conventional polymerase chain reaction (PCR), mycobacteria growth indicator tube (MGIT) 960, histopathological examination, and clinical follow-up of patients in diagnosing of smear-negative tuberculous lymphadenopathy...

Primary sinonasal tuberculosis remains a diagnostic challenge as it mimics sinonasal granulomatous disease or neoplasms. Its characteristic signs and symptoms may be non-specific and highly variable. Here we report a unique clinical condition of a 24-year-old man who presented with unilateral nasal obstruction and epiphora for 2 years. He was without any comorbidity, was immunocompetent, and was otherwise healthy. Subsequent investigations, including a computed tomography scan of the paranasal sinuses, and perioperative findings revealed a sinonasal mass involving the lateral nasal wall and paranasal sinuses...
