Klebsiella variicola is considered an emerging pathogen in humans and has been described different environments. K. belongs to pneumoniae complex, which expanded the taxonomic classification hindered epidemiological evolutionary studies. The present work describes molecular epidemiology of based on MultiLocus Sequence Typing (MLST) developed for this purpose. In total, 226 genomes obtained from public data bases 28 isolates were evaluated, mainly humans, followed by plants, various animals,...
spp. isolates from community-acquired infections were characterized. A total of 39
Antibiotic resistance has emerged as a global threat to public health, generating growing interest in investigating the presence of antibiotic-resistant bacteria environments influenced by anthropogenic activities. Wastewater treatment plants hospital serve significant reservoirs antimicrobial-resistant bacteria, where favorable environment is established, promoting proliferation and transfer genes among different bacterial species. In our study, we isolated total 243 strains from 5...
Worldwide, malaria parasites are increasingly resistant to available antimalarial drugs, which difficult treatment and control. Alternative drugs could exploit the differences between hosts parasite responses reactive oxygen nitrogen species. Malaria (Plasmodium sp) exposed oxidative stress as a result of their metabolic processes hosts’ infection, both in vertebrate vector mosquitoes. Host erythrocyte hemoglobin digestion heme production within food vacuoles synthesis folding proteins...
Carbapenem-resistant Gram-negative bacteria isolated in Venezuela have been poorly characterized. The present study characterized a total of 34 isolates obtained from 27 patients; five these patients were multi-infected. bacterial species identified Klebsiella pneumoniae (17), Pseudomonas aeruginosa (9), and Acinetobacter baumannii (8). From isolates, 85% as carbapenemase-producing bacteria, the carbapenemase genes blaKPC-2 (10/29 [34.4%]), blaVIM-type (7/29 [24.1%]), blaOXA-23 blaNDM-1...
For malaria transmission, Plasmodium parasites must develop in the mosquito vector. Oxidative stress insect midgut, triggered by environmental changes (e.g., pH and temperature), influences cellular signaling involved differentiation from gametocytes to mobile ookinetes for purpose of parasite survival. activates homeostatic response characterized phosphorylation eIF2α, attenuation protein synthesis, transcription genes participating unfolded antioxidant processes, forming a part an...
The use of colistin in food-producing animals favors the emergence and spread colistin-resistant strains. Here, we investigated occurrence molecular mechanisms resistance among E. coli isolates from a Mexican piglet farm. A collection 175 cephalosporin-resistant colonies swine fecal samples were recovered. phenotype was identified by rapid polymyxin test mcr-type genes screened PCR. We assessed strains antimicrobial susceptibility test, pulse-field gel electrophoresis, plasmid profile,...
We investigated the phenotypic and molecular characteristics of Extended-Spectrum-β-lactamase (ESBL)-producing Escherichia coli Klebsiella pneumoniae clinical isolates from four health-care institutions in Hermosillo, Sonora, Mexico. ESBL-producing were collected February to August 2016. The prevalence E. K. was 11.9 8.7%, respectively. High dissemination resistance ciprofloxacin (88%), trimethoprim/sulfamethoxazole (72%) aminoglycosides (59%) detected, as well susceptibility meropenem,...
Introduction: Hypervirulent strains of Klebsiella pneumoniae have gained clinical and epidemiological interest because their capacity to cause severe life-threatening infections.
 Methodology: We report a case involving infection with hypervirulent K. K2 strain that caused liver abscess in young woman type 1 diabetes Mexico.
 Results: The was found be associated biliary tract communication. virulence factors capsular serotypes were identified by polymerase chain reaction analysis....
Escherichia coli has emerged as an important pathogen in urinary tract infections (UTIs) due to the rapid acquisition of antibiotic resistance genes. This enhances ability E. colonize and creates therapeutic challenges within healthcare system. study aimed identify extended spectrum beta-lactamase (ESBL) O25b-ST131 pandemic clones isolated from two hospitals Mexico. Bacterial identification susceptibility tests were conducted using VITEK 2 The ESBL plasmid-mediated quinolone (PMQR) genes...
Abstract A molecular characterization of a plasmid-born qepA gene in (ESBL)-producing E. coli clinical isolates were performed. An 2.63% (11/418) positive isolates, which 90.0% carried CTX-M-15 (9/11) and SHV-12 (1/11). All showed chromosomal mutations the gyrA parC genes. The clonal groups A, B C identified belonged to, respectively, phylogroups B1 D, as well sequence types 205, 405 617. Several plasmid profiles determined with incompatibility FIA, FIB FII. genetic environment pEC8020 was...
