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 ...
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 ...
Biological Characterization of Hepatitis B virus Genotypes: Their Role in Viral Replication and Antigen Expression
(Frontiers Media, 2021-11)
Hepatitis B virus (HBV) inter-host evolution has resulted in genomic diversification reflected in the existence of nine genotypes (A-I) and numerous subgenotypes. There is growing evidence that genotypes influence HBV ...
Resistance of Collard Green Genotypes to Bemisia tabaci Biotype B: Characterization of Antixenosis
(2018-08-01)
Bemisia tabaci (Genn.) biotype B (Hemiptera: Aleyrodidae) is an important pest of vegetable crops, including collard greens Brassica oleracea var. acephala (Brassicaceae). The use of resistant genotypes is an interesting ...
Genotyping of potentially pathogenic Acanthamoeba strains isolated from nasal swabs of healthy individuals in Peru
(Elsevier, 2013)
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 ...

Phenotypic and genotypic characterization of Prototheca zopfii in a dog with enteric signs
(Elsevier B.V., 2009-12-01)
This is a case report of enteric protothecosis caused by Prototheca zopfii in an eight-year-old male mixed breed dog with a history of chronic bloody diarrhea, loss of appetite and weight loss. Algae were isolated from ...
Implications of the inoculation method and environment in the selection of melon genotypes resistant to Didymella bryoniae
(2022-06-27)
The use of resistant melon cultivars is considered the most effective method to control gummy stem blight, caused by Didymella bryoniae. However, the selection of genotypes is influenced by environmental conditions and the ...
Perfil genotípico do HCV em portadores de hepatite C em Belo Horizonte, Minas Gerais Brasil
(Universidade Federal de Minas GeraisUFMG, 2007-09-28)
Hepatitis C virus (HCV), like other RNA virus, is characterized by a high genomic heterogeneity. To date, six different genotypes have been identified, with distinct geographical distribution. HCV genotype identification ...
High occurrence of Cryptosporidium ubiquitum and Giardia duodenalis genotype E in sheep from Brazil
(Versita, 2014-03-01)
In this paper we report the occurrence of zoonotic species of Cryptosporidium (C. ubiquitum and C. parvum subtype IIaA15G2R1) and the host-specific Giardia duodenalis genotype E in a sheep farm from Brazil. Fecal specimens ...
