Genomic insights into ESBL-producing isolated from non-human primates in the Peruvian Amazon.

Introduction: Extended-spectrum beta-lactamase (ESBL)-producing are on the WHO priority pathogens list because they are associated with high mortality, health-care burden, and antimicrobial resistance (AMR), a serious problem that threatens global public health and should be addressed through the One Health approach. Non-human primates (NHP) have a high risk of acquiring these antibiotic-resistant bacteria due to their close phylogenetic relationship with humans and increased anthropogenic activities in their natural environments. This study aimed to detect and analyze the genomes of ESBL-producing (ESBL-producing ) in NHP from the Peruvian Amazon.

Genomic analysis of multidrug-resistant Escherichia coli strains carrying the mcr-1 gene recovered from pigs in Lima-Peru.

Antibiotic resistance is a current problem that significantly impacts overall health. The dissemination of antibiotic resistance genes (ARGs) to urban areas primarily occurs through ARG-carrying bacteria present in the gut microbiota of animals raised in intensive farming settings, such as pig production. Hence, this study aimed to isolate and analyzed 87 Escherichia coli strains from pig fecal samples obtained from intensive farms in Lima Department.

Occurrence and Genomic Characterization of -Harboring Isolates from Chicken and Pig Farms in Lima, Peru.

Resistance to colistin generated by the gene in is of great concern due to its efficient worldwide spread. Despite the fact that the Lima region has a third of the Peruvian population and more than half of the national pig and poultry production, there are no reports of the occurrence of the gene in isolated from livestock. In the present work, we studied the occurrence of carrying the gene in chicken and pig farms in Lima between 2019 and 2020 and described the genomic context of the gene.

Genomic Characterization of Typhimurium Isolated from Guinea Pigs with Salmonellosis in Lima, Peru.

subsp. serovar Typhimurium ( Typhimurium) is one of the most important foodborne pathogens that infect humans globally. The gastrointestinal tracts of animals like pigs, poultry or cattle are the main reservoirs of serotypes.

Carnivore protoparvovirus 1 in Peruvian dogs: Temporal/geographical and evolutionary dynamics of virus.

Canine parvovirus (CPV) has been recognized all around the world as the causal agent of a contagious and highly mortal disease in domestic dogs. In Peru, the infection is endemic and unvaccinated animals and puppies are the most at risk. In order to analyze viral diversity and determine the evolutionary genetic relationships and transmission dynamic of Peruvian CPV-2, were collected during the period of 2016-2017 rectal swabs from puppies with parvovirosis compatible symptoms.

Canine parvovirus types 2a and 2c detection from dogs with suspected parvoviral enteritis in Peru.

Canine parvovirus type 2 (CPV-2) has been reported worldwide as the main agent related to acute hemorrhagic enteritis of high morbidity and variable mortality in puppies. The detection and characterization of this virus is essential to understand the etiology of the disease and to develop control measures. To characterize the virus circulating in Peruvian dogs and to provide new insights into the local diversity of CPV-2, rectal swabs from 39 puppies with clinical symptoms and with no history of previous vaccinations were analyzed.

Presence and molecular characterisation of Giardia and Cryptosporidium in alpacas (Vicugna pacos) from Peru.

The presence of Giardia and Cryptosporidium was investigated in 274 faecal samples of alpacas (Vicugna pacos) from 12 herds from Peru by immunofluorescence microscopy and PCR amplification and sequencing of fragments of the ssu-rRNA and β-giardin genes from Giardia spp., as well as the ssu-rRNA gene from Cryptosporidium spp. A total of 137 samples (50.
