Determinacion de cromosomas holocineticos a través de la secuencia CID (cenp) en Dermaptera y Neuroptera (Insecta)

During cell division, the centromere is an indispensable chromosomal region to ensure the segregation of geneticsinformation. In most eukaryotes, the identity of the centromere is determined by the presence of the CENP protein(CID in Diptera). Some groups of animals have chromosomes that lack localized centromeres (holocentric); a clearexample of this is Dermaptera, although the holocentricity of their chromosomes is questioned since structuressimilar to centromeres were observed in them. It is also believed that neuroptera carries chromosomes with localizedcentromeres (monocentric), but recent studies have questioned this assertion since Chrysoperla presentschromosomes lacking centromeres. The aim of this work was to determine the holocentricity of chromosomes ofDoru linerae, D. luteipes (Dermaptera) and Chrysoperla externa (Neuroptera) by amplifying the CENP gen. Usingthe Quiagen extraction kit, total DNA was obtained fromf Droshophila melanogaster, Zaprionus indianus gupta(Diptera) and Astylus atromaculatus (Coleoptera) species with monocentric chromosomes and the target species. Theprimers used were: Fw-5´GAGAACGGAGCTTGGGTT3´; Rv5´CGTCGGCGAACAACTCAAG3´. PCRamplification was performed with conventional protocols. The final product was identified in 1% agarose gel. ThePCR reaction was positive for Diptera and Coleoptera. The lack of amplicons of CENP gen in Doru and Chrysoperlais another fact that demonstrates the holocentricity of their chromosomes.Fil: Silenzi Usandivaras, Gabriela Maria.

A snapshot of antimicrobial resistance in Mexico. Results from 47 centers from 20 states during a six-month period.

AIM:We aimed to assess the resistance rates of antimicrobial-resistant, in bacterial pathogens of epidemiological importance in 47 Mexican centers. MATERIAL AND METHODS:In this retrospective study, we included a stratified sample of 47 centers, covering 20 Mexican states. Selected isolates considered as potential causatives of disease collected over a 6-month period were included. Laboratories employed their usual methods to perform microbiological studies. The results were deposited into a database and analyzed with the WHONET 5.6 software. RESULTS:In this 6-month study, a total of 22,943 strains were included. Regarding Gram-negatives, carbapenem resistance was detected in ≤ 3% in Escherichia coli, 12.5% in Klebsiella sp. and Enterobacter sp., and up to 40% in Pseudomonas aeruginosa; in the latter, the resistance rate for piperacillin-tazobactam (TZP) was as high as 19.1%. In Acinetobacter sp., resistance rates for cefepime, ciprofloxacin, meropenem, and TZP were higher than 50%. Regarding Gram-positives, methicillin resistance in Staphylococcus aureus (MRSA) was as high as 21.4%, and vancomycin (VAN) resistance reached up to 21% in Enterococcus faecium. Acinetobacter sp. presented the highest multidrug resistance (53%) followed by Klebsiella sp. (22.6%) and E. coli (19.4%). CONCLUSION:The multidrug resistance of Acinetobacter sp., Klebsiella sp. and E. coli and the carbapenem resistance in specific groups of enterobacteria deserve special attention in Mexico. Vancomycin-resistant enterococci (VRE) and MRSA are common in our hospitals. Our results present valuable information for the implementation of measures to control drug resistance
