Fungi of the Scopulariopsis genus, commonly found in the environment, are opportunistic pathogens that can cause various types of human infections. So far, no efficient molecular method has been developed for species differentiation among Scopulariopsis and related genera. In order to advance this field, we have evaluated performance of polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) assays, based on cytochrome c oxidase subunit 1 and β-tubulin genes. The assays resulted in 2-10 restriction patterns, depending on the gene amplified and restriction enzyme applied. Pooled analysis of the patterns allowed to propose an algorithm, that can be successfully used for an accurate species-specific identification of 21 species of the Scopulariopsis-like fungi.

Background/aims: DNA isolation is the initial process in genetic research. The product is used in many PCR reactions (PCR-RFLP, Real-Time PCR, multiplex PCR). That is why it is important to optimize DNA isolation protocol to obtain a good quality of DNA.

Plaque psoriasis (PP) is a chronic immune-mediated skin disorder with a genetic basis, characterized by abnormal T-cell responses. This study investigated the role of gene variants rs2280883 and rs3761548 in T-cell regulation through their effects on IL-10 and TGF-β1 cytokine levels and their association with PP risk. A case-control study was conducted, including 101 individuals with PP and 106 healthy controls from the Mexican population.

Objectives: The present study aimed to investigate the association between certain interleukin-17 A (IL-17 A) polymorphisms, specifically rs2275913 and rs8193036, and the susceptibility to pulmonary tuberculosis (PTB). Considering the function of IL-17 A in regulating immunological responses, especially regarding bacterial infections, we sought to determine if variations in the IL-17 A gene effect on PTB in the examined group.
Methods: We performed a case-control study with 100 individuals who were confirmed to have PTB and 100 control subjects.

Background: Leishmaniasis is a parasitic disease caused by an intracellular protozoan, Leishmania. Various factors, including host immunity and the Leishmania species, influence the manifestation and severity of the disease. Recent investigations have shed light on the potentially significant role of Leishmania RNA virus (LRV) in the clinical prognosis of leishmaniasis.

Laos, Khmer, Kui, and Yer ethnic populations had a high prevalence of α-thalassemia, but the genetic background remains poorly understood. This study examined genetic variation at the α-globin gene cluster and three VNTR loci (D1S80, D17S5, and TPO) in these ethnic populations. For α-globin haplotype analysis, 110 subjects with normal α-globin and 232 subjects with α-thalassemia were selected to analyze six polymorphic sites using the PCR-RFLP technique.
