\u3ci\u3eAcmaeodera moesta\u3c/i\u3e Dugès, 1891 (Coleoptera: Buprestidae), a poorly known species from Mexico

Two new state records are reported for the Mexican Acmaeodera moesta Dugès (Coleoptera: Bu­prestidae), a lectotype is designated for it, and clarifying discussion is provided. According to Westcott (2020) there are 152 described valid species of Acmaeodera Eschscholtz in Mexico. Acmaeodera moesta Dugès (Fig. 1–3) was described from the state of Guanajuato, and it has not since been men­tioned in the literature except for listings in catalogs and checklists. Herein we record it from the states of México (MEX) and San Luis Potosí (SLP), designate a lectotype, and provide a detailed discussion

Cluster analysis as a methodology within phylogenetic systematics to construct phylogenetic trees

All evolutionary studies of groups of species are based on the choice of appropriate characteristics for rebuilding their phylogenies (a phylogeny is the relationship or kinship among species in general and tries to reconstruct evolutionary relationships). A phylogenetic analysis reconstructs the evolutionary relationships between species, which descend from common ancestors and, furthermore, which are the genetic distances or separation times between these species [1]. To generate a phylogenetic analysis characters must have two requirements: independent of each other and be homologous, they have the same origin and the same function in all organisms Study The nature of those characters can be varied. Any source of validated and proved phylogenetic information can provide characters for an evolutionary study. Among the main evolutionary studies that have been developed stand two methods: The methods that have been taken as morphological characters base in which the presence of physical characteristics that describe the species is identified, and methods that have been based on molecular characteristics as the sequence DNA [2]. These characters are recorded in a data matrix within which, the state in which the character has been observed is represented with zero if it is absent or one if present respectively, and whether it is a character that may be present in the species with different values (multi-state) within the data matrix can be represented by the value corresponding to that character [2]. For this reason, homologous characters, once they have been validated and proven, may be taken as the basis for an evolutionary study because they provide enough information for the reconstruction of a phylogenetic tree

A new palm seed host and new distribution record for \u3ci\u3eCaryoborus chiriquensis\u3c/i\u3e (Sharp, 1885) (Coleoptera: Bruchidae)

Wettinia praemorsa (Willd.) Wessels Boer is recorded as a new host for Caryoborus chiriquensis (Sharp, 1885) and an estimate of damage to the seeds is given. The geographical distribution of this palm bruchid now extends to Venezuela

First report of \u3ci\u3eDesmiphora hirticollis\u3c/i\u3e (Olivier) (Coleoptera: Cerambycidae) on \u3ci\u3eWigandia urens\u3c/i\u3e (Ruiz and Pavón) H.B.K. (Hydrophilaceae) in Mexico

ABSTRACT. Desmiphora hirticollis (Olivier) (Coleoptera: Cerambycidae) was found in Oaxaca, Mexico, feeding in the stems of Wigandia urens (Ruiz and Pavón) H.B.K. (Hydrophilaceae), a new host record. Information about damage in the plant stems and some observations of the insect’s biology are provided. RESUMEN. Se reporta por primera vez en México la presencia del cerambícido Desmiphora hirticollis (Olivier) (Coleoptera: Cerambycidae) alimentándose de los tallos de Wigandia urens (Ruiz and Pavón) H.B.K. (Hydrophilaceae). Se proporciona información sobre los daños que provoca este insecto a los tallos de la planta, así como algunas observaciones biológicas del insecto

International Nosocomial Infection Control Consortiu (INICC) report, data summary of 43 countries for 2007-2012. Device-associated module

We report the results of an International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2007-December 2012 in 503 intensive care units (ICUs) in Latin America, Asia, Africa, and Europe. During the 6-year study using the Centers for Disease Control and Prevention's (CDC) U.S. National Healthcare Safety Network (NHSN) definitions for device-associated health care–associated infection (DA-HAI), we collected prospective data from 605,310 patients hospitalized in the INICC's ICUs for an aggregate of 3,338,396 days. Although device utilization in the INICC's ICUs was similar to that reported from ICUs in the U.S. in the CDC's NHSN, rates of device-associated nosocomial infection were higher in the ICUs of the INICC hospitals: the pooled rate of central line–associated bloodstream infection in the INICC's ICUs, 4.9 per 1,000 central line days, is nearly 5-fold higher than the 0.9 per 1,000 central line days reported from comparable U.S. ICUs. The overall rate of ventilator-associated pneumonia was also higher (16.8 vs 1.1 per 1,000 ventilator days) as was the rate of catheter-associated urinary tract infection (5.5 vs 1.3 per 1,000 catheter days). Frequencies of resistance of Pseudomonas isolates to amikacin (42.8% vs 10%) and imipenem (42.4% vs 26.1%) and Klebsiella pneumoniae isolates to ceftazidime (71.2% vs 28.8%) and imipenem (19.6% vs 12.8%) were also higher in the INICC's ICUs compared with the ICUs of the CDC's NHSN
