Mycobacterium tuberculosis infection is associated with thrombocytosis. We sought to determine if this information might be valuable in evaluating granulomas using acid-fast stains (AFS). Fifty-eight patients with culture-confirmed M tuberculosis infection were compared with 75 patients with atypical mycobacterial infection and 48 patients negative for mycobacteria. Thrombocytosis (platelet cou...

A study was conducted to find out the prevalence of bovine tuberculosis (BTB) in Nili Ravi buffaloes at a livestock experimental station in the Punjab, Pakistan. On the basis of the comparative intradermal tuberculin test (CIDT), prevalence of BTB was found to be 10.06%. Epidemiological factors including old age, high milk production and parity played a significant role in the prevalence of the...

Numerous atypical mycobacteria, including Mycobacterium abscessus (Mabc), cause nontuberculous mycobacterial infections, which present a serious public health threat. Inflammasome activation is involved in host defense and the pathogenesis of autoimmune diseases. However, inflammasome activation has not been widely characterized in human macrophages infected with atypical mycobacteria. Here, we...

background: although, nontuberculous mycobacteria can cause disease in different organisms, they usually are not reported in most countries because scientists in general consider them as non-pathogens. but, increasing nontuberculous mycobacteria diseases occurrence has changed this belief. nevertheless, there is no meta-analysis review about prevalence of nontuberculous mycobacteria in iran. me...

a nested polymerase chain reaction (pcr) assay with two pairs of primers was applied for the detection of m. tuberculosis complex dna in specimens of 51 patients. of these, 31 clinically diagnosed patients (group i) recruited from july 1996 to june 1997 were given antituherculous chemotherapy from one to six months with standard daily regimen (isaniazid, 5 mg/kg; rifampin, 10 mg/kg; pyrazinamit...

Atypical fibroxanthoma (AFX) is a spindle cell neoplasm with low metastatic potential but high tendency to recur after surgery. Because of the rarity of this lesion and its aspecific clinical features, AFX could be easily misdiagnosed and undertreated by many clinicians who encounter them. Dermoscopy represents a valuable tool for easily assessing skin lesions, even though histological examinat...

Objective(s) In addition to several molecular methods and in particular 16S rDNA analysis, the application of a more discriminatory genetic marker, i.e., 16S-23S internal transcribed spacer gene sequence has had a great impact on identification and classification of mycobacteria. In the current study we aimed to apply this sequencing power to conclusive identification of some Iranian clinical ...
