Molecular characterization of the Hepatitis B virus genotypes in Colombia: A Bayesian inference on the genotype F
(ELSEVIER SCIENCE BV, 2011)
Hepatitis B is a worldwide health problem affecting about 2 billion people and more than 350 million are chronic carriers of the virus. Nine HBV genotypes (A to I) have been described. The geographical distribution of HBV ...
Imputation of non-genotyped individuals using genotyped progeny in Nellore, a Bos indicus cattle breed
(Elsevier B.V., 2014-08-01)
This study aimed at imputing non(un)-genotyped sires using a stepwise imputation approach that combines identity by descent (IBD) detection methods with other imputation algorithms. We also studied the effect of using ...
KSHV genotypes A and C are more frequent in Kaposi sarcoma lesions from Brazilian patients with and without HIV infection, respectively
(Elsevier B.V., 2011-02-01)
The present study aimed to evaluate the frequency of KSHV genotypes isolated from Kaposi sarcoma (KS) lesions in patients from Brazil. Fifty KS cases were evaluated. The most frequently detected viral genotypes were A ...

Genotyping of potentially pathogenic Acanthamoeba strains isolated from nasal swabs of healthy individuals in Peru
Free Living Amoebae (FLA) of Acanthamoeba genus are widely distributed in the environment and can be found in the air, soil and water; and have also been isolated from air-conditioning units. In humans, they are causative ...
Optimum sowing date and genotype testing for upland rice production in Brazil
A better understanding of widespread agricultural practices adopted in the region of Ribeira Valley, São Paulo, Brazil for upland rice (Oryza sativa L.) production is needed. The objectives of this study were to determine ...
Genotypic characterization of enterotoxigenic escherichia coli strains causing traveler's diarrhea
(American Society for Microbiology, 2013)
This study aims to characterize the presence of virulence factors of enterotoxigenic Escherichia coli (ETEC) causing traveler's diarrhea. Among 52 ETEC isolates, the most common toxin type was STh, and the most frequent ...
Genotype variation of citrus tristeza virus after passage on different hosts, and changes in the virus genotype populations by the vector aphis gossypii
(Mediterranean Phytopathological Union, Italia, 2022)
Phylogenetic analyses categorize seven genotypes of citrus tristeza virus (CTV). The symptoms caused by this pathogen, their expression and severity are influenced by CTV genotypes, host species, cultivars, and infected ...
Genotypic characterization by MLST of Ornithobacterium rhinotracheale from poultry in Peru
(Universidad Nacional Mayor de San Marcos, 2021)
The aim of this study was the genotyping of Ornithobacterium rhinotracheale. For this, 36 strains were identified by molecular testing and genotyping was performed by Multilocus Sequence Typing (MLST). The tests identified ...
