SARS-CoV-2: theoretical analysis of the proposed algorithms to the enhancement and segmentation of high-resolution microscopy images-Part II.

Today is a reality that the novel coronavirus SARS-Cov-2 has become a global pandemic. For this reason, the study of real microscopic images of this coronavirus is of great importance, as it allows us to carry out a more precise research on it. However, as we pointed out in a former paper as reported by Roberto Rodríguez (SARS-CoV-2: Enhancement and Segmentation of High-Resolution Microscopy Images.

Defining Fluoroquinolone Resistance-Mediating Mutations from Non-Resistance Polymorphisms in Topoisomerases.

Often dismissed as a commensal, is an increasingly prominent target of research due to its role in septic arthritis and organ transplant failure in immunosuppressed patients, particularly lung transplantation. As a mollicute, its highly reductive genome and structure render it refractile to most forms of treatment and growing levels of resistance to the few sources of treatment left, such as fluoroquinolones. We examined antimicrobial susceptibility (AST) to fluoroquinolones on 72 isolates and observed resistance in three (4.

SARS-CoV-2: preliminary study of infected human nasopharyngeal tissue by high resolution microscopy.

Background: The novel coronavirus SARS-CoV-2 is the etiological agent of COVID-19. This virus has become one of the most dangerous in recent times with a very high rate of transmission. At present, several publications show the typical crown-shape of the novel coronavirus grown in cell cultures.

SARS-CoV-2: enhancement and segmentation of high-resolution microscopy images-Part I.

Possibly, and due to poor eating habits and unhealthy lifestyle, many viruses are transmitted to human people. Such is the case, of the novel coronavirus SARS-Cov-2, which has expanded of exponential way, practically, to whole world population. For this reason, the enhancement of real microscopic images of this coronavirus is of great importance.

First detection and characterization of macrolide-resistant Mycoplasma pneumoniae strains in Cuba.

Objectives: Mycoplasma pneumoniae is a common cause of community-acquired pneumonia in humans. Treatment of infections can be complicated by the occurrence of macrolide resistant strains. The study was conducted to evaluate the presence of resistant strains in Cuba and to determine the corresponding genotypes.

Macrolide-resistant Mycoplasma genitalium infections in Cuban patients: an underestimated health problem.

Background: The increasing prevalence of macrolide resistant Mycoplasma genitalium is a major concern worldwide. In Cuba, several cases of clinical treatment failure with 1 g single dose and extended azithromycin regimen have been detected and the aim of the present investigation was to retrospectively determine the prevalence of macrolide-resistance mediating mutations (MRMM) in M. genitalium-positive samples conserved at the Cuban National Reference Laboratory of Mycoplasma Research between 2009 and 2016.

Mycoplasma genitalium infections in Cuba: surveillance of urogenital syndromes, 2014-2015.

Mycoplasma genitalium is an emerging sexually transmitted pathogen implicated in urethritis in men and several inflammatory reproductive tract syndromes in women. The prevalence of M. genitalium infections in Cuban patients with urogenital syndromes is unknown.

Antimicrobial Susceptibility Patterns of Recent Cuban Mycoplasma genitalium Isolates Determined by a Modified Cell-Culture-Based Method.

Isolation of Mycoplasma genitalium from clinical specimens remains difficult and few strains are available for antimicrobial susceptibility testing. We describe the antimicrobial susceptibility of M. genitalium strains grown in Vero cell culture with first- and second- line antibiotics, using a modified cell-culture-based method.

Design, optimization and evaluation of a polymerase chain reaction for detection of borrelia spp.

Background: Lyme borreliosis and relapsing fever are important zoonotic diseases worldwide and the improvement of diagnostic strategies is a prioritized task considering the morbidity of these diseases in some areas. PCR based methods appear to be of utmost importance because of the high sensitivity and specificity of these assays.

Objectives: To obtain a molecular method based on PCR for the detection of the genus Borrelia infection in different specimens.

Mycoplasma hominis in Cuban Trichomonas vaginalis isolates: association with parasite genetic polymorphism.

Trichomonas vaginalis can be naturally infected with intracellular Mycoplasma hominis. This bacterial infection may have implications for trichomonal virulence and disease pathogenesis. The objective of the study was to report the presence of M.
