The aim of the study was to analyze genotype I hepatitis A virus (HAV) 5' nontranslated region (NTR) sequences from a recent outbreak in South Korea and compare them with reported sequences from Japan. We collected a total of 54 acute hepatitis A patients' sera from HAV genotype I [27 severe disease (prothrombin time INR ≥ 1.50) and 27 mild hepatitis (prothrombin time INR <1.00)], performed nes...

The complete genome sequence of the enterovirus 71 strain CSF15/YN/CHN/2013, first isolated from cerebrospinal fluid of a child in Yunnan, China, in 2013, was determined. According to the phylogenetic and homogeneity analyses, the isolate was assigned to subgenotype C4a.

We assessed neurologic sequelae associated with an enterovirus 71 (EV71) outbreak in South Korea during 2009. Four of 94 patients had high signal intensities at brainstem or cerebellum on magnetic resonance imaging. Two patients died of cardiopulmonary collapse; 2 had severe neurologic sequelae. Severity and case-fatality rates may differ by EV71 genotype or subgenotype.

We sequenced the complete genome of bovine viral diarrhea virus (BVDV) strain UM/126/07. It belongs to subgenotype 1h. The complete genome is composed of 12,196 nucleotides organized as one open reading frame encoding 3,898 amino acids. This is the first report of a full-length sequence of BVDV-1h.

To gain further insight into the genomic features of bovine viral diarrhea virus 1 (BVDV-1) subgenotypes, we sequenced the complete genome of BVDV-1n Shitara/02/06 and BVDV-1o IS26NCP/01. The complete genome of Shitara/02/06 and IS26NCP/01 shared 77.7 to 79.3% and 78.0 to 85.7% sequence identities with other BVDV-1 subgenotype strains, respectively.

Molecular characterization of two sewage-borne pathogens identified hepatitis A virus (HAV) subgenotype IA and Giardia duodenalis assemblages A and B as predominant genotypes circulating in an urban area of Venezuela. This study reveals epidemiological features of human pathogens of worldwide distribution and the efficacy of molecular methods for accurate assessment of sewage pollution.

Two isolates of a new classical swine fever virus (CSFV) subgenotype, 2.1c (HNLY-2011 and HNSD-2012), were recently isolated from pigs in Hunan Province, China. The most significant difference in the amino acid sequences of the polyproteins from subgenotypes 2.1a and 2.1b is an SPA → TPV amino acid substitution at positions 777 and 779 in the E2 protein.

BACKGROUND Hepatitis B virus (HBV) infection is a major public health problem globally. HBV genotypes and subgenotypes influence disease transmission, progression, and treatment outcome. A study was conducted among treatment naive chronic HBV patients in southern Vietnam to determine the genotypes and subgenotypes of HBV. METHODS A prospective, exploratory study was conducted among treatment ...

The genome sequence of a new strain of Newcastle disease virus (NDV) (chicken/Pak/Quality Operations Lab/SFR-611/13) is reported here. The strain was isolated from a vaccinated chicken flock in Pakistan in 2013 and has panzootic features. The genome is 15,192 nucleotides in length and is classified in subgenotype VIIi of genotype VII, class II.
