Drug susceptibility profile of 53 Mycobacterium tuberculosis clinical isolates was studied by conventional solid and liquid culture methods. Forty three isolates were drug resistant to at least one drug and 10 were susceptible. The strain identification was performed by PCR amplification of mtp40 gene and strain subtyping was performed by Double Repetitive Element-PCR (DRE-PCR), IS6110 outward ...
In the US eradication program for bovine tuberculosis, a definitive diagnosis depends on the isolation of Mycobacterium bovis. However, in some cases bacterial culture is unsuccessful, even though the tissue is considered suspicious by histopathology because granulomatous lesions and acid-fast organisms are present. The purpose of this study was to determine if polymerase chain reaction (PCR) t...
This study reports on the transmission of Mycobacterium tuberculosis of the same IS6110 RFLP type between two acquaintances with open pulmonary tuberculosis and a five-year-old Doberman bitch. No clinical signs, gross lesions at necropsy or histopathological lesions were observed in the infected lungs and gastrointestinal tract of the dog, although M. tuberculosis was directly detected by IS611...
In this study, Mycobacterium tuberculosis complex isolates recovered from respiratory and nonrespiratory specimens with culture were evaluated using an automatized PCR method. Specimens with suspected tuberculous disease were decontaminated and concentrated using the standard N-acetyl-L-cysteine NaOH method and were inoculated onto glycerol-supplemented Löwenstein-Jensen media and BACTEC B12 vi...
dear editor-in-chief we read with interest the study by khazaei et al. (1) in which the authors have nicely concluded that pcr is more sensitive test than ziehl-neelsen staining and histo-pathological examination for the diagnosis of tuberculosis (tb). they have rightly pointed to use pcr, selectively, in acidfast bacilli negative paucibacillary forms of tb. however, we intend to highlight few ...
[Nested-PCR for gene that encodes the antigen b applied to the diagnosis of pulmonary tuberculosis].
The polymerase chain reaction used for amplifying an internal sequence of a previously amplified fragment (nested-PCR) was investigated as a complementary alternative for searching for alcohol-acid resistant bacilli and Mycobacterium tuberculosis cultures in Lowenstein-Jensen medium. 144 sputum samples were investigated from patients with suspected tuberculosis that were sent to the Tuberculosi...
conclusions the detection of mycobacterium tuberculosis is always an important differential diagnosis for skin and soft tissue involvement in endemic areas. the cold abscess is an uncommon form of cutaneous tuberculosis that can be single or multiple and with or without fistula. case presentation the case was a 42-year-old female, a known case of rheumatoid arthritis that was receiving predniso...
The diagnosis of intraocular tuberculosis has been a challenge until the introduction of polymerase chain reaction (PCR) to detect the mycobacterial-specific DNA sequence in the intraocular fluids. Such investigations have confirmed diverse manifestations of intraocular tuberculosis including retinal vasculitis and serpiginouslike choroiditis. The latter may manifest with multifocal lesions inv...
We used multilocus PCR and electrospray ionization mass spectrometry (PCR/ESI-MS) to determine the genotype and drug resistance profiles for 96 Mycobacterium tuberculosis isolates circulating in regions of high and low tuberculosis (TB) endemicity in China. The dominant principal genetic group (PGG) circulating in China was PGG1, and drug-resistant gene mutations were more diversified in the re...
