Detection and genetic characterization of deltacoronavirus in pigs, Ohio, USA, 2014.

ABSTRACT: In Ohio, United States, in early 2014, a deltacoronavirus was detected in feces and intestine samples from pigs with diarrheal disease. The complete genome sequence and phylogenetic analysis of the virus confirmed that the virus is closely related to a porcine deltacoronavirus (porcine coronavirus HKU15) reported in Hong Kong in 2012.

Detection and genetic characterization of porcine deltacoronavirus in Tibetan pigs surrounding the Qinghai-Tibet Plateau of China.

Project description:Porcine deltacoronavirus (PDCoV) is a recently discovered RNA virus that belongs to the family Coronaviridae and genus Deltacoronavirus. This virus causes enteric disease in piglets that is characterized by enteritis and diarrhoea. In our present investigation, 189 diarrhoeic samples were collected between July 2016 and May 2017 from Tibetan pigs inhabiting in three different provinces surrounding the Qinghai-Tibet Plateau of China. We then applied the molecular-based method of reverse transcription polymerase chain reactions (RT-PCRs) to detect the presence of PDCoV in collected samples, and RT-PCR indicated that the prevalence of PDCoV was 3.70% (7/189) in Tibetan pigs. Four of 7 PDCoV-positive pigs were monoinfections of PDCoV, three samples were co-infections of PDCoV with porcine epidemic diarrhoea virus (PEDV), and 52 (27.51%) samples were positive for PEDV. Four strains with different full-length genomes were identified (CHN/GS/2016/1, CHN/GS/2016/2, CHN/GS-/2017/1 and CHN/QH/2017/1), and their genomes were used to analyse the characteristics of PDCoV currently prevalent in Tibetan pigs. We found a 3-nt insertion in the spike gene in four strains in Tibetan pigs. Phylogenetic analysis of the complete genome and spike and nucleocapsid gene sequences revealed that these strains shared ancestors with the strain CHN-AH-2004, which was found in pigs from the Anhui province of China mainland. However, PDCoV strains from Tibetan pigs formed different branches within the same cluster, implying continuous evolution in the field. Our present findings highlight the importance of epidemiologic surveillance to limit the spread of PDCoV in livestock at high altitudes in China.

Full-Length Genome Sequence of Porcine Deltacoronavirus Strain USA/IA/2014/8734.

Project description:Porcine deltacoronavirus (PDCoV) was detected in feces from diarrheic sows during an epidemic of acute and transmissible diarrhea. No transmissible gastroenteritis virus or porcine epidemic diarrhea virus was detected. The PDCoV USA/IA/2014/8734 from the herd was sequenced for full-length genomic RNA to further characterize PDCoV in U.S. swine.

Project description:BACKGROUND: Over the last decade, nosocomial infections due to Acinetobacter baumannii have been described with an increasing trend towards multidrug resistance, mostly in intensive care units. The aim of the present study was to determine the clonal relatedness of clinical isolates and to elucidate the genetic basis of imipenem resistance. METHODS: A. baumannii isolates (n = 83) originated from two hospital settings in central Ohio were used in this study. Pulsed-field gel electrophoresis genotyping and antimicrobial susceptibility testing for clinically relevant antimicrobials were performed. Resistance determinants were characterized by using different phenotypic (accumulation assay for efflux) and genotypic (PCR, DNA sequencing, plasmid analysis and electroporation) approaches. RESULTS: The isolates were predominantly multidrug resistant (>79.5%) and comprised of thirteen unique pulsotypes, with genotype VII circulating in both hospitals. The presence of bla(OXA-23) in 13% (11/83) and IS(Aba1) linked bla(OXA-66) in 79.5% (66/83) of clinical isolates was associated with high level imipenem resistance. In this set of OXA producing isolates, multidrug resistance was bestowed by bla(ADC-25), class 1 integron-borne aminoglycoside modifying enzymes, presence of sense mutations in gyrA/parC and involvement of active efflux (with evidence for the presence of adeB efflux gene). CONCLUSION: This study underscores the major role of carbapenem-hydrolyzing class D beta-lactamases, and in particular the acquired OXA-23, in the dissemination of imipenem-resistant A. baumannii. The co-occurrence of additional resistance determinant could also be a significant threat.

Development and utilization of an infectious clone for porcine deltacoronavirus strain USA/IL/2014/026.

Project description:We report the generation of a full-length infectious cDNA clone for porcine deltacoronavirus strain USA/IL/2014/026. Similar to the parental strain, the infectious clone virus (icPDCoV) replicated efficiently in cell culture and caused mild clinical symptoms in piglets. To investigate putative viral interferon (IFN) antagonists, we generated two mutant viruses: a nonstructural protein 15 mutant virus that encodes a catalytically-inactive endoribonuclease (icEnUmut), and an accessory gene NS6-deletion virus in which the NS6 gene was replaced with the mNeonGreen sequence (icDelNS6/nG). By infecting PK1 cells with these recombinant PDCoVs, we found that icDelNS6/nG elicited similar levels of type I IFN responses as icPDCoV, however icEnUmut stimulated robust type I IFN responses, demonstrating that the deltacoronavirus endoribonuclease, but not NS6, functions as an IFN antagonist in PK1 cells. Collectively, the construction of a full-length infectious clone and the identification of an IFN-antagonistic endoribonuclease will aid in the development of live-attenuated deltacoronavirus vaccines.

Detection and Genetic Characterization of Adenovirus Type 14 Strain in Students with Influenza-Like Illness, New York, USA, 2014-2015.

Project description:During the 2014-15 influenza season, 13/168 respiratory samples from students with influenza-like illness (ILI) at a college in New York, USA, were positive for human adenovirus (HAdV); 4/13 samples were positive for HAdV-B14p1. During influenza season, HAdV should be included in the differential diagnostic panel used to determine the etiology of ILI.

Molecular and Clinical Comparison of Enterovirus D68 Outbreaks among Hospitalized Children, Ohio, USA, 2014 and 2018.

Project description:Enterovirus D68 (EV-D68) causes respiratory tract infections and neurologic manifestations. We compared the clinical manifestations from 2 EV-D68 outbreaks in 2014 and 2018 and a low-activity period in 2016 among hospitalized children in central Ohio, USA, and used PCR and sequencing to enable phylogenetic comparisons. During both outbreak periods, infected children had respiratory manifestations that led to an increase in hospital admissions for asthma. The 2018 EV-D68 outbreak appeared to be milder in terms of respiratory illness, as shown by lower rates of pediatric intensive care unit admission. However, the frequency of severe neurologic manifestations was higher in 2018 than in 2014. During the same period in 2016, we noted neither an increase in EV-D68 nor a significant increase in asthma-related admissions. Phylogenetic analyses showed that EV-D68 isolates from 2018 clustered differently within clade B than did isolates from 2014 and are perhaps associated with a different EV-D68 subclade.

Genetic characterization and pathogenicity of Japanese porcine deltacoronavirus.

Project description:Porcine deltacoronavirus (PDCoV) have recently emerged in several swine producing countries. Our survey found that in addition to porcine epidemic diarrhoea virus (PEDV), PDCoV has also been a causative enteric pathogen of diarrhoeic outbreaks occurring at swine farms around Japan since late 2013. Phylogenetic analysis using the complete genomes of PDCoVs detected in Japan in 2014 demonstrated that the PDCoVs from Japan may be closely related to the PDCoVs from the U.S. and Korea during 2013 to 2014 but not the PDCoVs from China and Hong Kong during 2004 to 2016 and from Thailand, Vietnam and Laos during 2015 to 2016. To investigate the pathogenicity of a representative Japanese PDCoV, we performed an experimental infection using hysterectomy-produced colostrum-deprived piglets. The PDCoV-inoculated piglets showed acute, watery diarrhoea, but all recovered and survived. In addition, all piglets inoculated with the Japanese PDCoV exhibited virus shedding at high level in faeces and viremia corresponding to their clinical symptoms. In the PDCoV-inoculated group, viruses were mainly detected from jejunums to colons by a quantitative PDCoV-specific PCR and microscopic observation. These findings would provide useful information for establishing a diagnostic methodology for distinguishing diarrhoea caused by PDCoV from that caused by other enteric pathogens, such as PEDV.
