The São Paulo state citrus belt in Brazil is a major production region. Since at least 1957, plantations this region have been affected by canker, an economically damaging disease caused Xanthomonas citri subsp. (Xcc). For about 50 years, until 2017, canker eradication programme was carried out In work, our aim to investigate the effects of on genetic variability and evolution Xcc. To end, we sequenced analysed 758 Xcc genomes sampled belt, together with 730 publicly available from around...
Human-to-animal transmission events of SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) have been reported in both domestic and wild species worldwide. Despite the high rates contagion mortality during COVID-19 (Coronavirus Diseases 2019) pandemic Peru, no instances natural virus infection documented animals, particularly Amazonian regions where human–wildlife interactions are prevalent. In this study, we conducted a surveillance investigation using viral RNA sequencing fecal...
Salmonella Gallinarum (SG) is the causative agent of fowl typhoid (FT), a disease that harmful to poultry industry. Despite sanitation and prophylactic measures, this pathogen associated with frequent outbreaks in developing countries, causing high morbidity mortality. We characterized complete genome sequence Colombian SG strains then performed comparative analysis other found different regions worldwide. Eight field plus 9R-derived vaccine were subjected whole-genome sequencing (WGS)...
Introduction Extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae are on the WHO priority pathogens list because they associated with high mortality, health-care burden, and antimicrobial resistance (AMR), a serious problem that threatens global public health should be addressed through One Health approach. Non-human primates (NHP) have risk of acquiring these antibiotic-resistant bacteria due to their close phylogenetic relationship humans increased anthropogenic activities...
Resistance to colistin generated by the mcr-1 gene in Enterobacteriaceae is of great concern due its efficient worldwide spread. Despite fact that Lima region has a third Peruvian population and more than half national pig poultry production, there are no reports occurrence Escherichia coli isolated from livestock. In present work, we studied E. carrying chicken farms between 2019 2020 described genomic context gene. We collected fecal samples 15 4 provinces including capital Metropolitana...
Salmonella enterica subsp. serovar Typhimurium (S. Typhimurium) is one of the most important foodborne pathogens that infect humans globally. The gastrointestinal tracts animals like pigs, poultry or cattle are main reservoirs serotypes. Guinea pig meat an protein source for Andean countries, but this animal commonly infected by S. Typhimurium, producing high mortality rates and generating economic losses. Despite its impact on human health, food security, economy, there no genomic...
Salmonella Gallinarum (SG) is a host-restricted enterobacteria and the causative agent of fowl typhoid in poultry. Here, we report complete genomes two strains belonging to this serotype. SA68 field strain isolated from livers dead hen carcasses commercial layer farm presenting high mortality located São Paulo city, Brazil, 1990. Strain 9R corresponds live attenuated SG vaccine. DNA was extracted pure cultures subjected whole genome sequencing (WGS) using Ion Torrent PGM System. The...
Antibiotic resistance is a current problem with great impact on health in general. The spread of antibiotic genes (ARGs) to urban regions occurs mainly through ARG-carrying bacteria present the gut microbiota animals reared under intensive farming conditions, such as pig production. Therefore, study, 87 Escherichia coli were isolates from fecal samples farms located Lima Department and analyzed by Kirby-Bauer Disk Diffusion Susceptibility Test PCR for mcr-1 gene identification. diffusion...
