How does a Saccharomyces cerevisiae extract influence the components of isolated rotavirus particles from stool samples collected in a clinical setting from children? Saudi J Biol Sci 2024; 31:104031. [PMID: 38946847 PMCID: PMC11214517 DOI: 10.1016/j.sjbs.2024.104031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2024] [Revised: 05/21/2024] [Accepted: 05/25/2024] [Indexed: 07/02/2024] Open
Abstract
Human Rotavirus (HRV) is the causative pathogen of severe acute enteric infections that cause mortality among children worldwide. This study focuses on developing a new and effective treatment for rotavirus infection using an extract from Saccharomyces cerevisiae, aiming to make this treatment easily accessible to everyone. 15 antigens and 26 antibodies were detected in serum and stool using ELISA. The titers of HRVq1, HRVq2, HRVC1, and HRVC2 on Vero cells were determined to be 1.2x106, 3.0x106, 4.2x106, and 7.5x105 (Plaque forming unit, PFU/ml) four days after infection, respectively. The HRVq1 isolate induced cytopathic effects, i.e., forming multinucleated, rounded, enlarged, and expanding gigantic cells. RT-PCR identified this isolate, and the accession number 2691714 was assigned to GeneBank. The molecular docking analysis revealed that nonstructural proteins (NSPs) NSP1, NSP2, NSP3, NSP4, NSP5, and NSP6 exhibited significant binding with RNA. NSP2 demonstrated the highest binding affinity and the lowest binding energy (-8.9 kcal/mol). This affinity was maintained via hydrophobic interactions and hydrogen bonds spanning in length from 1.12 Å to 3.11 Å. The ADMET and bioactivity predictions indicated that the yeast extract possessed ideal solubility, was nontoxic, and did not cause cancer. The inhibitory constant values predicted for the S. cerevisiae extract in the presence of HRV vital proteins varied from 5.32 to 7.45 mM, indicating its potential as a viable drug candidate. Saccharomyces cerevisiae extract could be utilized as a dietary supplement to combat HRV as an alternative dietary supplement.

Abstract
Livestock excrement is a major pollutant yielded from husbandry and it has been constantly imported into various related environments. Livestock excrement comprises a variety of microorganisms including certain units with health risks and these microorganisms are transferred synchronically during the management and utilization processes of livestock excrement. The livestock excrement microbiome is extensively affecting the microbiome of humans and the relevant environments and it could be altered by related environmental factors as well. The zoonotic microorganisms, extremely zoonotic pathogens, and antibiotic-resistant microorganisms are posing threats to human health and environmental safety. In this review, we highlight the main feature of the microbiome of livestock excrement and elucidate the composition and structure of the repertoire of microbes, how these microbes transfer from different spots, and they then affect the microbiomes of related habitants as a whole. Overall, the environmental problems caused by the microbiome of livestock excrement and the potential risks it may cause are summarized from the microbial perspective and the strategies for prediction, prevention, and management are discussed so as to provide a reference for further studies regarding potential microbial risks of livestock excrement microbes.

Abstract
Rotavirus genotypes are species specific. However, interspecies transmission is reported to result in the emergence of new genotypes. A cross-sectional study of 242 households with 281 cattle, 418 goats, 438 pigs, and 258 humans in Uganda was undertaken between 2013 and 2014. The study aimed to determine the prevalence and genotypes of rotaviruses across co-habiting host species, as well as potential cross-species transmission. Rotavirus infection in humans and animals was determined using NSP3 targeted RT-PCR and ProSpecT Rotavirus ELISA tests, respectively. Genotyping of rotavirus-positive samples was by G- and P-genotype specific primers in nested RT-PCR assays while genotyping of VP4 and VP7 proteins for the non-typeable human positive sample was done by Sanger sequencing. Mixed effect logistic regression was used to determine the factors associated with rotavirus infection in animals. The prevalence of rotavirus was 4.1% (95% CI: 3.0–5.5%) among the domestic animals and 0.8% (95% CI: 0.4–1.5%) in humans. The genotypes in human samples were G9P[8] and P[4]. In animals, six G-genotypes, G3(2.5%), G8(10%), G9(10%), G11(26.8%), G10(35%), and G12(42.5%), and nine P-genotypes, P[1](2.4%), P[4](4.9%), P[5](7.3%), P[6](14.6%), P[7](7.3%), P[8](9.8%), P[9](9.8%), P[10](12.2%), and P[11](17.1%), were identified. Animals aged 2 to 18 months were less likely to have rotavirus infection in comparison with animals below 2 months of age. No inter-host species transmission was identified.

Abstract
Picobirnaviruses (PBVs), detected in a wide range of host species, are viruses of which limited information is available about their pathogenic potential, ecology, or evolutionary characteristics. In this study, a molecular analysis of segment 2 encoding the PBV RNA-dependent RNA-polymerase (RdRp) in small ruminants with diarrhea in Turkey was undertaken. A total of 66 fecal samples or gut contents from diarrheic small ruminants including 55 sheep and 11 goats were screened. Four samples (6.06%), obtained from sheep in different farms, yielded the expected amplicon size for the genogroup I RdRp gene fragment, whereas no positivity was detected for genogroup II PBVs. Phylogenetic analysis revealed high levels of genetic diversity among the genogroup I PBVs. Additionally, all PBV infected sheep were also positive for rotavirus A. This study, reporting the presence of the PBVs in sheep Turkey for the first time, contributes to the molecular characterization and epidemiology of PBVs.

Abstract
The surveillance studies for the presence of caprine rotavirus A (RVA) are limited in India, and the data for the whole-genome analysis of the caprine RVA is not available. This study describes the whole-genome-based analysis of a caprine rotavirus A strain, RVA/Goat-wt/IND/K-98/2015, from a goat kid in India. The genomic analysis revealed that the caprine RVA strain K-98, possess artiodactyl-like and DS-1 human-like genome constellation G8P[1]-I2-R2-C2-M2-A3-N2-T6-E2-H3. The three structural genes (VP2, VP4, and VP7) were close to caprine host having nucleotide-based identity range between 97.5 and 98.9%. Apart from them, other gene segments showed similarity with either bovine or human like genes, ultimately pointing toward a common evolutionary origin having an artiodactyl-type backbone of strain K-98. Phylogenetically, the various genes of the current study isolate also clustered inside clades comprising Human-Bovine-Caprine isolates from worldwide. The current findings add to the knowledge on caprine rotaviruses and might play a substantial role in designing future vaccines or different alternative strategies combating such infections having public health significance. To the best of our knowledge, this is the first report on the whole-genome characterization of a caprine RVA G8P[1] strain from India. Concerning the complex nature of the K-98 genome, whole-genome analyses of more numbers of RVA strains from different parts of the country are needed to comprehend the genomic nature and genetic diversity among caprine RVA.

Abstract
Rotavirus A (RVA) is the primary cause of acute dehydrating diarrhea in human and numerous animal species. Animal-to-human interspecies transmission is one of the evolutionary mechanisms driving rotavirus strain diversity in humans. We screened fresh feces from 416 bats (201 Pteropus medius, 165 Rousettus leschenaultii and 50 Taphozous melanopogon) for RVA using rRT-PCR. We detected a prevalence of 7% (95% CI 3.5-10.8) and 2% (95% CI 0.4-5.2) in P. medius and R. leschenaultii, respectively. We did not detect RVA in the insectivorous bat (T. melanopogon). We identified RVA strains similar to the human strains of G1 and G8 based on sequence-based genotyping, which underscores the importance of including wildlife species in surveillance for zoonotic pathogens to understand pathogen transmission and evolution better.

Abstract
Although members of rotavirus group A (RVA) are major enteric pathogens of humans and animals of many species, their impact on the health of small ruminants is not well documented. In this study, we conducted a molecular analysis of VP4, VP7, VP6 and NSP4 genes of RVAs detected using a commercial antigen ELISA in small ruminants with or without diarrhea in Turkey. Of the RVAs detected in sheep, one strain (Kutahya) was characterized as genotype G8P[1]-I2-E2. Two others (Ankara-1 and Ankara-2) were identified as NSP4 E2 and VP6 I2 genotypes, although they were untyped for the VP4 and VP7 genes. The RVAs from two goats were characterized as genotype G6P [1]-I2-E2. This is the first detection of in goats RVA genotypes G6P [1], which had previously only been found in cattle in Turkey, and of RVA in sheep. The study extends our current knowledge about the circulation of two RVA G genotypes, G6 and G8, in goat herds, and the detection of the G8 genotype in sheep in Turkey. This provides further information about the molecular epidemiology of RVAs in different animal species and indicates that additional surveillance programs are needed to determine the epidemiology of RVA in small ruminants and other species.

Abstract
The circulation of G8 RVA strains in calves with diarrhea detected first time in Turkey. First report on whole genome of G8P[5] RVA strains from calves with diarrhea in Turkey. VP7 gene of the both Turkish bovine RVA strains showed the closest with human RVA strains detected in Europe and Africa. The genotype constellation of the strains is G8-P[5]-I2-R2-C2-M2-A3-N2-T6-E2-H3. The findings raise provocative questions related to strain-specific vaccine effectiveness in herds where commercial RVA vaccines are routinely utilized.
Group A rotaviruses (RVA) are regarded as major enteric pathogens of large ruminants, including cattle. Rotavirus vaccines administered to pregnant cows are commonly used to provide passive immunity that protects newborn calves from the clinical disease. In this study we report the detection of RVA from calves with severe diarrhea in a herd regularly vaccinated to prevent enteric infections including RVA. Diarrheic disease was observed in newborn calves aged 4–15 days, with high morbidity and mortality rates, but no diarrhea was seen in adult animals. Rotavirus antigen was detected by enzyme-immunoassay in the intestinal content or the fecal samples of all examined animals. Besides RVA, bovine coronavirus and bovine enteric calicivirus were detected in some samples. Selected RVA strains were characterized by whole genome sequencing. Two strains, RVA/Cow-wt/TUR/Amasya-1/2015/G8P[5] and RVA/Cow-wt/TUR/Amasya-2/2015/G8P[5] were genotyped as G8-P[5]-I2-R2-C2-M2-A3-N2-T6-E2-H3 and showed >99% nucleotide sequence identity among themselves. This genomic constellation is fairly common among bovine RVA strains; however, phylogenetic analysis of the G8 VP7 gene showed close genetic relationship to some European human RVA strains (up to 98.4% nt identity). Our findings is the first indication regarding the circulation of G8 RVA strains in Turkey. Given that the administered RVA vaccines contained type G6 and G10 VP7 antigens some concerns raised with regard to the level of heterotypic protection elicited by the vaccine strains against circulating bovine G8 RVA strains. Enhancement of surveillance of circulating RVA strains in calves across Turkey is needed to support ongoing vaccination programs.

Abstract
Rotavirus was detected in samples from lambs with diarrhoea. Salmonella enterica subsp. diarizonae was isolated in samples from lambs with diarrhoea. Antibiotic resistance was detected in >60% of Escherichia coli strains isolated in the study. Escherichia coli with identical antibacterial resistance were detected in lambs and puppies.
Objectives of the present work were (i) to confirm pathogens implicated in cases of diarrhoea in newborn and young lambs in sheep farms in Greece and (ii) to investigate a possible relation in dissemination of pathogens between lambs and dogs present in the farm. Work was carried out in 22 sheep farms, with (i) flock size over 150 animals, (ii) presence of clinical signs of diarrhoea in lambs in the flock and (iii) close and continuous contact and movement of shepherd dogs within the animal shed of each farm. Faecal sample collection from lambs was performed within 48 h of onset of clinical signs and prior to administration of any antimicrobial or antiparasitic medication to lambs. Faecal samples were also collected from puppies in the farm. In total, samples were collected from 126 lambs and 58 puppies. Samples were processed by using established techniques for isolation of bacteria, detection of viruses and observation of protozoan oocycts. Escherichia coli isolates obtained during the study, were tested for antimicrobial resistance against a variety of antimicrobial agents. In total, 236 bacterial isolates were recovered from faecal samples of lambs and 165 isolates from faecal samples of puppies. E. coli was the most frequently isolated microorganism: 104 isolates from lambs and 109 isolates from puppies were recovered. Other bacteria isolated were Enterobacter spp., Proteus spp., Klebsiella spp., (lambs and puppies), Clostridium perfringens, Citrobacter freundi, Salmonella enterica subsp. diarizonae (only lambs) and Streptococcus spp. (only puppies). Group A Rotavirus was detected in samples from lambs (2.5%) and Parvovirus in samples from puppies (5%). Cryptosporidium spp. oocysts were observed in samples from lambs and puppies. This is the first report of isolation of S. enterica subsp. diarizonae and of detection of Rotavirus from lambs in Greece. Rates of E. coli isolates from puppies resistant to antimicrobial agents were, in general, smaller than respective rates in isolates from lambs. Two pairs of isolates from the same farm (one from a lamb and one from a puppy) with identical patterns of resistance to antimicrobial agents were detected, which provides some evidence in support of a hypothesis that members of each pair might possibly have been spread from one animal species to the other.

Abstract
Diarrhoea in lambs and kids is often a complex, multi-factorial syndrome. Common infectious causes of diarrhoea in lambs and kids during the first month of life are of bacterial or parasite nature. However, despite appreciable improvements in management practices and prevention and treatment strategies over the last decades, diarrhoea is still a common and costly syndrome affecting newborn small ruminants. Recent advances in the diagnostics and metagenomic investigations of the enteric environment have allowed discovering a number of novel viruses, although their pathobiological properties remain largely unknown. Assessing more in depth the impact of these viruses on the health and productions of these livestock animals is necessary and requires the development of accurate diagnostic tools and updating of the diagnostic algorithms of enteric pathological conditions.

Abstract
Surveillance of rotavirus infections and circulating strains in small ruminants (i.e. lambs, goats and camelids) has been a neglected research area in the past. However, recent years that have seen an intensification of surveillance in humans and livestock animals, where vaccines to reduce disease burden caused by Rotavirus A (RVA) are available, led to the efforts to better understand the epidemiology, ecology and evolution of RVA strains in other hosts, including lambs, goats and camelids. The aim of this review is to provide an update of the epidemiology and strain diversity of RV strains in these species through searching for relevant information in public data bases.

Louge Uriarte EL, Badaracco A, Matthijnssens J, Zeller M, Heylen E, Manazza J, Miño S, Van Ranst M, Odeón A, Parreño V. The first caprine rotavirus detected in Argentina displays genomic features resembling virus strains infecting members of the Bovidae and Camelidae. Vet Microbiol 2014; 171:189-97. [PMID: 24742949 DOI: 10.1016/j.vetmic.2014.03.013] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2013] [Revised: 03/08/2014] [Accepted: 03/10/2014] [Indexed: 11/18/2022]
Abstract
Rotavirus group A (RVA) is a major cause of diarrhea in humans and young animals including small ruminants. The purpose of this study was to identify RVA in dairy goat kids, and to characterize the complete genomic constellation and genetic relatedness with other RVA strains. Four out of twenty fecal samples from diarrheic and non-diarrheic goat kids were positive for RVA by ELISA. A representative sample was selected for further genome analyses. The RVA strain RVA/Goat-wt/ARG/0040/2011/G8P[1] displayed the following genomic constellation: G8-P[1]-I2-R5-C2-M2-A3-N2-T6-E12-H3, reminiscent to guanaco and other bovine-like RVA strains detected in Argentina. Phylogenetic analyses revealed that most of the genome segments had a rather close relatedness with RVA strains typically obtained from cattle, sheep, South American camelids and goats. Interestingly, strain 0040 possessed the R5 and E12 genotypes which have up to date only been found in different animal species from Argentina. Overall, these findings suggest that strain 0040 could represent a typical goat RVA genome constellation similar to those previously found in other animal species within the order Artiodactyla.
