Occurrence of Yam Mosaic Virus and Yam Mild Mosaic Virus on spp. Germplasm Collection in Cuba-Epidemiology of Associated Diseases.

Potyvirus diseases are one of the main challenges facing the production of yam ( spp.). The objective of this study was to identify the potyviruses present in the spp.

Detection of Genes in Hospital-Acquired MRSA and SOSA Strains Associated with Biofilm Formation.

Methicillin-resistant (MR) (SA) and others, except for (SOSA), are common in healthcare-associated infections. SOSA encompass largely coagulase-negative staphylococci, including coagulase-positive staphylococcal species. Biofilm is encoded by the operon and is involved in virulence.

Aptamers: A Cutting-Edge Approach for Gram-Negative Bacterial Pathogen Identification.

Early and accurate diagnoses of pathogenic microorganisms is essential to correctly identify diseases, treating infections, and tracking disease outbreaks associated with microbial infections, to develop precautionary measures that allow a fast and effective response in epidemics and pandemics, thus improving public health. Aptamers are a class of synthetic nucleic acid molecules with the potential to be used for medical purposes, since they can be directed towards any target molecule. Currently, the use of aptamers has increased because they are a useful tool in the detection of specific targets.

Quorum Quenching with a Diffusible Signal Factor Analog in .

is a multidrug-resistant Gram-negative bacillus associated with nosocomial infections in intensive care units, and nowadays, its acquired resistance to trimethoprim-sulfamethoxazole (SXT) by genes within class 1 integrons is a worldwide health problem. Biofilm and motility are two of the major virulence factors in this bacterium and are auto-induced by the diffusible signal factor (DSF). In recent studies, retinoids have been used to inhibit (Quorum Quenching) these virulence factors and for their antimicrobial effect.

Isolation and Identification of Multidrug-Resistant Clones from the Hospital Environment.

Global dispersion, hospital outbreaks, and lineage relationships between emerging antibiotic-resistant strains such as are of public health interest. This study aimed to isolate and identify clones from third-level healthcare hospitals in Mexico to establish their multidrug-resistant phenotype, phylogeny, and prevalence. Biological and abiotic surface samples were used to isolate strains and to test their antibiotic susceptibility to classify them.

Helicobacter pylori: detection of iceA1 and iceA2 genes in the same strain in Mexican isolates.

Background And Aims: Helicobacter pylori iceA1 and iceA2 gene amplification is usually performed to identify mixed populations as both genes are apparently reportedly exclusive. However, some strains isolated from Mexico show both iceA genes. The aim of this study was to establish the frequency of these genes in Mexican isolates and genomic diversity of the H.

Detection of the glmM gene in Helicobacter pylori isolates with a novel primer by PCR.

A novel reverse primer (GLM MR1) was designed for detection of the glmM gene in Helicobacter pylori by PCR. The percentage of amplification in clinical isolates using GLM MR1 was 100% for detection of the glmM gene and 86.36% for the ureA gene.
