Conteúdo: |
In this study, avian extraintestinal Escherichia coli obtained from the liver of poultry carcasses approved for human consumption in the State of Pernambuco-Brazil were tested for antibiotic plus serum-resistance. Liver samples (n=110) were obtained from one slaughterhouse and 88 bacterial isolates were identified as Escherichia coli. The antibiotic-resistance profiles of antibiotics used in human and/or veterinary practice were accessed by the disk-diffusion method. Phenotypes with high resistance to streptomycin (84.0%), tetracycline (44.7%), amikacin (29.8%), gentamicin (21.3%) and ciprofloxacin (21.3%) were identified. Resistance to antibiotics such as ceftazidime, amoxicillin-clavulanic acid and imipenem was also recorded. Twenty isolates with distinct antibiotic-resistance and susceptibility profiles were selected for serum resistance assays, phylogenetic characterization and detection of the iss gene. We have shown that multidrug resistant isolates were often simultaneously resistant to broiler and human sera. Phylogenetic characterization of serum- plus antibiotic-resistant isolates have shown three belonging to group D, eleven to group B1, one to group B2, and five to group A. We concluded that commensal E. coli strains isolated from the liver of healthy poultry carcasses can harbor and potentially share multidrug-plus virulence genes found in pathogenic pathotypes. This suspicion was not related to specific phylogenetic groups or presence of the iss gene. |

The aim of this study was to determine the forest species trees and shrubs that occur in the Amhara region, Ethiopia, for determining the possible areas for collecting seeds and propagations to meet genetic conservation and use programs as well as the recovery of degraded areas. The study was conducted at Fudi Natural Forest in Fagta Lekoma district, Amhara region, northwestern Ethiopia. Using geographic information systems (GISs), the points of presence of species were plotted on the USGS SRTM map (GTOPO30) at 1 : 250,000 scale (USGS, 2018) using Arc GIS 10.1 software (ESRI, 2011). The map has been cropped and presented only for the citizens that contained points of presence of the species. Figures were generated in the JPG format for each species individually, presenting the distribution of each according to the altitude of the region. The maps were elaborated using multiple linear regressions, relating the bioclimatic variables with the numerical models of latitude, longitude, and altitude. Descriptive statistical analysis was initially performed. This was followed by performing a normality test to observe the data distribution. In the region, 1250 individuals of 32 families and 46 species were surveyed. The families most found in the northeast, north, northwest, southwest, southeast, and west regions were Mimosoideae, Euphorbiaceae, Celastraceae, and Rubiaceae. |
