Abstract
Infection by hepatitis B virus (HBV) is responsible for approximately 296 million chronic cases of hepatitis B, and roughly 880,000 deaths annually. The global burden of HBV is distributed unevenly, largely owing to the heterogeneous geographic distribution of its subtypes, each of which demonstrates different severity and responsiveness to antiviral therapy. It is therefore crucial to the global public health response to HBV that the spatiotemporal spread of each genotype is well characterized. In this study, we describe a collection of 133 newly sequenced HBV strains from recent African immigrants upon their arrival in Belgium. We incorporate these sequences-all of which we determine to come from genotypes A, D, and E-into a large-scale phylogeographic study with genomes sampled across the globe. We focus on investigating the spatio-temporal processes shaping the evolutionary history of the three genotypes we observe. We incorporate several recently published ancient HBV genomes for genotypes A and D to aid our analysis. We show that different spatio-temporal processes underlie the A, D, and E genotypes with the former two having originated in southeastern Asia, after which they spread across the world. The HBV E genotype is estimated to have originated in Africa, after which it spread to Europe and the Americas. Our results highlight the use of phylogeographic reconstruction as a tool to understand the recent spatiotemporal dynamics of HBV, and highlight the importance of supporting vulnerable populations in accordance with the needs presented by specific HBV genotypes.

Abstract
The present report communicates the first complete genome sequence of S-type Mycobacterium avium subsp. paratuberculosis, isolated from an organised goat herd in Uttar Pradesh, India. Bacteria were isolated in pure culture on Herrold's egg yolk medium (HEYM) slants containing mycobactin J from the faecal sample collected per-rectally from a clinical diseased goat, and next-generation sequencing (NGS) revealed that the genome sequence length of the isolated strain named MAP-Gt-9 is 4,509,428 bp with no plasmid DNA, with a GC content of 69.5%, an N50 value of 125,474 bp, and an L50 value of 12, containing 4235 coding DNA sequences (CDSs), 44 tRNAs, 3 ncRNAs and 1 each 5S, 16S, 23S rRNA genes.

Detection of Q129H Immune Escape Mutation in Apparently Healthy Hepatitis B Virus Carriers in Southwestern Nigeria. Viruses 2021; 13:v13071273. [PMID: 34210073 PMCID: PMC8310067 DOI: 10.3390/v13071273] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Revised: 06/27/2021] [Accepted: 06/27/2021] [Indexed: 12/12/2022] Open
Abstract
As the global effort to eradicate hepatitis B continues, immune escape mutations (IEMs) and drug resistance mutations (DRMs) affecting its diagnosis, treatment, and prevention are compromising this goal. However, knowledge about the prevalence and circulation of these mutations in Nigeria is scarce. Serum samples (n = 199) from apparently healthy prospective blood donors, pregnant women, and individuals presenting with fever in southwestern Nigeria were analyzed for the presence of IEMs and DRMs by means of nested PCR in the HBV S (HBs) and HBV polymerase (Pol) genes, followed by phylogenetic and mutational analyses. In total, 25.1% (n = 50/199) of samples were positive for HBV, as measured by PCR. In 41 samples (20.6%), both fragments could be amplified, whereas the HBs gene and the Pol gene fragment alone were detected in 0.5% (n = 1/199) and 4% (n = 8/199) of samples, respectively. Sequences were successfully obtained for all 42 HBs gene fragments but for only 31/49 Pol gene fragments (totaling 73 sequences from 44 individuals). All sequences were identified as HBV genotype E. IEMs were present in 18.2% (n = 8/44) of the sequences of HBV-positive individuals with available sequences. IEM Q129H was detected in eight out of the 44 (18.2%) HBV isolates sequenced in this study; however, no DRMs were observed. This study confirms the circulation of HBV IEMs and reports the presence of Q129H IEM for the first time in Nigeria. Intensified research on the dynamics of IEM is necessary in order to enhance the elimination of HBV.

Nutritional status and screening tools to detect nutritional risk in hospitalized patients with hepatic echinococcosis. ACTA ACUST UNITED AC 2020; 27:74. [PMID: 33357363 PMCID: PMC7758020 DOI: 10.1051/parasite/2020071] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Accepted: 12/07/2020] [Indexed: 11/14/2022]
Abstract
Background: Echinococcosis is a chronic consumptive liver disease. Little research has been carried out on the nutritional status of infected patients, though liver diseases are often associated with malnutrition. Our study investigated four different nutrition screening tools, to assess nutritional risks of hospitalized patients with echinococcosis. Methods: Nutritional Risk Screening 2002 (NRS 2002), Short Form of Mini Nutritional Assessment (MNA-SF), Malnutrition Universal Screening Tool (MUST), and the Nutrition Risk Index (NRI) were used to assess 164 patients with alveolar echinococcosis (AE) and 232 with cystic echinococcosis (CE). Results were then compared with European Society for Clinical Nutrition and Metabolism (ESPEN) criteria for malnutrition diagnosis. Results: According to ESPEN standards for malnutrition diagnosis, 29.2% of CE patients and 31.1% of AE patients were malnourished. The malnutrition risk rates for CE and AE patients were as follows: NRS 2002 – 40.3% and 30.7%; MUST – 51.5% and 50.9%; MNA-SF – 46.8% and 44.1%; and NRI – 51.1% and 67.4%. In patients with CE, MNA-SF and NRS 2002 results correlated well with ESPEN results (k = 0.515, 0.496). Area-under-the-curve (AUC) values of MNA-SF and NRS 2002 were 0.803 and 0.776, respectively. For patients with AE, NRS 2002 and MNA-SF results correlated well with ESPEN (k = 0.555, 0.493). AUC values of NRS 2002 and MNA-SF were 0.776 and 0.792, respectively. Conclusion: This study is the first to analyze hospitalized echinococcosis patients based on these nutritional screening tools. Our results suggest that NRS 2002 and MNA-SF are suitable tools for nutritional screening of inpatients with echinococcosis.
