Introduction: The complete genome of the marine environmental bacterium Vibrio diabolicus isolated from raw shrimp in the city of Guadalajara in the state of Jalisco in Mexico is reported here.
Methodology: Vibrio spp. it was isolated and identified using standard microbiological and molecular techniques.
SARS-CoV-2 was first detected in the city of Wuhan, Hubei Province, China. In this report, we describe the complete genome sequence of the first imported SARS-CoV-2, detected in a Mexican patient who had traveled to Bergamo, Italy. Phylogenetic analysis showed that this isolate belongs to subclade A2a (lineage G) and is closely related to isolates from Finland, Germany and Brazil, all of which were from patients with a history of travel to Italy.

We present the case of a 25-year-old male patient, immunocompetent, with cervical lymphadenopathy, identifying Mycobacterium kumamotonense, a rare species in extrapulmonary forms and with a high drug resistance index.

Objective: To know the frequency of M.
Background: Tuberculosis is a global public health problem, especially in emerging countries. Mycobacterium tuberculosis is the main cause of cervical lymphadenopathy; nontuberculous mycobacteria are relatively common in children and rare in adults.
Objective: To identify and establish the frequency of infectious etiology by nontuberculous mycobacteria in Mexican adult patients with cervical lymphadenopathy.
Background: Tuberculosis is a public health problem, extrapulmonary presentations have increased, it is difficult to diagnose because of the low bacillary load.
Objective: To identify risk factors and to evaluate the efficiency of diagnostic methods in pleural, meningeal, peritoneal and pericardial tuberculosis.
Methods: Prospective study of cases and controls.
Background: There is a progressive increase in nontuberculous mycobacteria (NTM) in pulmonary and extrapulmonary infections that might cause confusion with the Mycobacterium tuberculosis complex. To determine the frequency of finding NTM in clinical samples from patients diagnosed with active tuberculosis, with negative acid-alcohol-resistant bacilli (acid-fast bacillus [AFB]) in a third-level specialty hospital's mycobacterial laboratory between January 2013 and December 2014.
Methods: This is a prospective, descriptive study where isolated strains of biological material were studied in Lowenstein-Jensen and BACTEC MGIT 960 cultures.
Background: Human enterovirus D68 (EV-D68) recently caused an increase in mild-to-severe pediatric respiratory cases in North America and some European countries. Even though few of these children presented with acute paralytic disease, direct causal relationship cannot yet be assumed.
Objectives: The purposes of this report were to describe the clinical findings of an outbreak of EV-D68 infection in Mexico City and identify the genetic relationship with previously reported strains.

The genus Psychrobacter contains environmental, psychrophilic and halotolerant gram-negative bacteria considered rare opportunistic pathogens in humans. Metagenomics was performed on the cerebrospinal fluid (CSF) of a pediatric patient with meningitis. Nucleic acids were extracted, randomly amplified, and sequenced with the 454 GS FLX Titanium next-generation sequencing (NGS) system.

Accurate identification of causative species is crucial for proper treatment and patient follow-up. However, several difficulties are associated with phenotypic and molecular diagnostic methods for precise identification at the species level due to shared metabolic and genetic characteristics.

Methods: We determined the resistance profile to 11 antibiotics (CLSI) and phenotypic ESBL detection following a disk diffusion method adapted for P. aeruginosa.
