Hepatitis b virus genotypes and drug resistance mutations circulating in blood donors in beira, mozambique

PLos ONE; 18 (2), 2023
Hepatitis B virus (HBV) infects nearly 300 million people and is the leading cause of hepatitis and hepatocellular carcinoma worldwide. Despite the high burden of HBV in sub-Saharan Africa, countries such as Mozambique have limited data available on circulating HBV genotypes and the presence of drug resi...

Genetic characterisation of south african and mozambican bovine rotaviruses reveals a typical bovine-like artiodactyl constellation derived through multiple reassortment events

PloS pathog; 20 (2), 2022
This study presents whole genomes of seven bovine rotavirus strains from South Africa and Mozambique. Double-stranded RNA, extracted from stool samples without prior adaptation to cell culture, was used to synthesise cDNA using a self-annealing anchor primer ligated to dsRNA and random hexamers. The cDNA...

Prevalence and genome characterization of porcine rotavirus A in southern Mozambique

Infect. gent. evol; 87 (), 2021
Rotavirus A (RVA) is an important pathogen causing gastroenteritis in many species, including humans and pigs. The objective of this study was to determine the prevalence of RVA in pigs from smallholdings and commercial farms in southern Mozambique and characterize the complete genomes of selected strain...

Evaluating the impact of sex-biased genetic admixture in the americas through the analysis of haplotype data

Genes (Basel); 12 (), 2021
A general imbalance in the proportion of disembarked males and females in the Americas has been documented during the Trans-Atlantic Slave Trade and the Colonial Era and, although less prominent, more recently. This imbalance may have left a signature on the genomes of modern-day populations characterise...

Frequencia e caracterização dos genótipos de rotavirus do grupo A em crianças de 0 a 59 meses de idade, atendidas com diarreeia aguda na pediatria do Hospital Central de Nampula, 2015

A doença diarreica na infância constitui um importante problema de saúde pública em Moçambique. A infecção pelo Rotavirus é a uma das causas mais comum de diarreia aguda grave a nível mundial, sendo a diarreia terceira causa de morbi-mortalidade infantil na maioria d...

Rotavirus a strains obtained from children with acute gastroenteritis in mozambique, 2012-2013: g and p genotypes and phylogenetic analysis of vp7 and partial vp4 genes

Arch. virol; 163 (1), 2018
In Mozambique rotavirus (RV) was shown to be the greatest cause of acute diarrhoea in infants from 0 to 11 months, and in 2015, national rotavirus vaccination was introduced. As with other developing countries, there is very limited active strain characterisation. Rotavirus positive clinical specimens, c...

Human Immunodeficiency Virus (HIV) Drug Resistance in African Infants and Young Children Newly Diagnosed With HIV: A Multicountry Analysis
Human Immunodeficiency Virus (HIV) Drug Resistance in African Infants and Young Children Newly Diagnosed With HIV: A Multicountry Analysis

Clin. infect. dis; 65 (12), 2017
Background. Programs for the prevention of mother-to-child transmission (PMTCT) of human immunodeficiency virus (HIV) have been scaled up in many low- and middle-income countries. However, HIV drug resistance (HIVDR) data among HIV-1– infected young children remain limited. Methods. Surveys of pretreat...

Epidemiology of rotavirus A diarrhea in Chókwè, Southern Mozambique, from February to September, 2011

Journal of Medical Virology; 88(10) (), 2016
Acute diarrhea disease caused by Rotaviruses A (RVA) is still the leading cause of morbidity and mortality in children ≤5 years old in developing countries. An exploratory cross-sectional study was conducted between February and September, 2011 to determine the proportion of acute diarrhea caused by RV...

Perfil de sensibilidade dos isolados de Mycobacterium tuberculosis de pacientes com tuberculose e coinfectados TB/HIV na cidade da Beira, Sofala, Moçambique

A tuberculose (TB) é uma doença infecciosa que ameaça a humanidade há séculos. Recentemente grandes avanços foram conseguidos no combate à tuberculose, entretanto a resistência bacilar e a coinfecção pelo Vírus de Imunodeficiência Humana (HIV) persistem como os principais desafios dos program...

Comparative Characterization of Vibrio cholerae O1 from Five Sub-Saharan African Countries Using Various Phenotypic and Genotypic Techniques

PLos ONE; 10 (11), 2015
We used standardized methodologies to characterize Vibrio cholerae O1 isolates from Guinea, Democratic Republic of the Congo (DRC), Togo, Côte d’Ivoire and Mozambique. We investigated 257 human isolates collected in 2010 to 2013. DRC isolates serotyped O1 Inaba, while isolates from other countries ser...
