Objective : The study aimed to evaluate molecular and immunological methods propose a workflow using them for tuberculosis (TB) diagnosis routine. Methods A cross-sectional retrospective was performed, including 121 liquid cultures from TB laboratory located in the extreme south of Brazil. All were positive Mycobacterium complex (MTBC) by in-house Polymerase Chain Reaction (PCR) DNA extracted C...

In the present study, serologic data were compared with data obtained by capillary PCR to establish the efficacy of capillary PCR for the determination of Mycoplasma infection in samples obtained from throat swabs, bronchoalveolar lavage fluids (BALF), and sputum of patients with Mycoplasma pneumonia. We performed PCR analysis for Mycoplasma DNA on a total of 325 samples from 197 patients with ...

background: trichomoniasis, caused by trichomonas vaginalis , is one of the most common sexually transmitted infections in the world. diagnosis of t. vaginalis is performed by different methods, including wet mount, culture, serological methods and pcr, which required laboratory equipments and expert laboratory personnel. the aim of this study was evaluation of immunochromatographic strip test ...

BACKGROUND Traditional methods of detecting Leishmania from cutaneous lesions involve invasive diagnostic procedures, such as scrapings, which cause discomfort, require technical expertise, and carry risks of invasive procedures. We compared the performance of 2 novel, molecular-based non-invasive methods for the diagnosis of cutaneous leishmaniasis (CL). METHODS Consecutive patients presenti...

In clinical situations where a diagnostic real-time PCR assay is not sensitive enough, leading to low or falsely negative results, or where detection earlier in a disease progression would benefit the patient, an unbiased pre-amplification prior to the real-time PCR could be beneficial. In Amp-PCR, an unbiased random Phi29 pre-amplification is combined with a specific real-time PCR reaction. Th...

BACKGROUND We noted a marked increase in Chlamydia trachomatis (CT) infections in the Capital Health Region of NS coincident with substitution of a PCR for an enzyme immunoassay (EIA). We reviewed our experience to determine the cost of switching and the impact on the number of new infections diagnosed. METHODS Information on the number of EIA and PCR tests performed on women was retrieved fr...

Objective(s): Listeria monocytogens, Bacillus cereus and Campylobacter jejuni are three toxin producing bacteria over the world, especially in Iran, and it is essential to find a certain, rapid procedure to identify these microorganisms. In this research, these bacteria were simultaneously detected by multiplex PCR technique in foods. Materials and Methods: The primary approval of bacterial str...
