Correction to: The pathogenic intestinal spirochaete Brachyspira pilosicoli forms a diverse recombinant species demonstrating some local clustering of related strains and potential for zoonotic spread

The article published in 2013 [1] described the use of the availableBrachyspira multilocus sequence typing (MLST) scheme [2] to characterize the population structure of the intestinal spirocheteBrachyspira pilosicoli. It used sequences of seven loci that were amplified from 131 strains that had been isolated from different geographical origins and species.

[UNEP] Nairobi -- As the COVID-19 pandemic continues to take lives and disrupt economies across the world, a new report warns that further outbreaks will emerge unless governments take active measures to prevent other zoonotic diseases from crossing into the human population, and sets out ten recommendations to prevent future pandemics.

[UNEP] Ebola, SARS, Zika, HIV/AIDS, West Nile fever and now COVID-19. These are some of the highest-profile diseases to emerge in the last several decades. And while they emerged in different parts of the world, they have one thing in common. They are what scientists call "zoonotic diseases," infections that jump between animals and humans, some of which leave illness and death in their wake.

This study aimed to evaluate the distribution and zoonotic transmission routes of Cryptosporidium species and microsporidia to humans referred to medical laboratories of Kurdistan Province, Iran. A total of 1,383 stool samples were collected and investigated. Cryptosporidium spp. and microsporidia were detected using microscopic methods (i.e., formol-ether concentration, Ziehl-Neelsen staining, and modified trichrome staining methods). DNA was extracted from positive samples, and specific fragments of the Cryptosporidium GP60 gene and microsporidia SSU rRNA gene were amplified. Furthermore, positive samples were sequenced ...

AbstractEmerging and re-emerging zoonotic diseases represent a public health challenge of international concern. They include a large group of neglected tropical diseases (NTDs), many of which are of zoonotic nature. Coronavirus disease 2019 (COVID-19), another emerging zoonotic disease, has just increased the stakes exponentially. Most NTDs are subject to the impact of some of the very same human-related activities triggering other emerging and re-emerging diseases, including COVID-19, severe acute respiratory syndrome (SARS), bird flu and swine flu. It is conceivable that COVID-19 will exacerbate the NTDs, as it will div...

AbstractEscherichia coli field isolates from calves were characterized and categorized into the most significant diarrheagenic pathotypes using polymerase chain reaction (PCR) assays with different specific primers. The used PCR systems were designed to detect sequences representing the group-specific virulence genes encoding fimbriaef5 (K99), Shiga toxins (stx1 andstx2), heat-stable enterotoxins (st), heat-labile enterotoxins (lt), intimin (eae), hemolysin (hylA), and EAEC heat-stable enterotoxin (astA). In the present work, a total of 150E. coli field isolates were recovered from 150 fecal swabs collected from 100 diarrh...

AbstractSpecies A rotaviruses (RVAs) are a leading cause of diarrhea in children and in the young of a large variety of mammalian and avian host species. The purpose of this study was to identify RVA in nomadic goats and calves during severe diarrhea outbreaks in 2012 and 2014 in Bouaarfa, Morocco, and to characterize the complete genomic constellation of two bovine and caprine strains (S18 and S19) and their genetic relatedness with the human strain ma31 detected in 2011 in Morocco. Partial nucleotide sequencing of VP4 and VP7 genes for the twenty-two positive samples revealed three circulating genotypes: G6P[14], G10P[14...

In this study, we report the discovery of PRV in Africa, in an Angolan soft-furred fruit bat (Lissonycteris angolensis ruwenzorii) from Bundibugyo District, Uganda. Metagenomic characterization of a rectal swab yielded 10 dsRNA genome segments, revealing this virus to cluster within the known diversity of PRV variants detected in bats and humans in Southeast Asia. Phylogeographic analyses revealed a correlation between geographic distance and genetic divergence of PRVs globally, which suggests a geographic continuum of PRV diversity spanning Southeast Asia to sub-Saharan Africa. The discovery of PRV in an African bat drama...
