Sequencing methods for HA and NA genes of avian influenza viruses from wild bird feces using Oxford Nanopore sequencing Comp. Immunol. Microbiol. Infect. Dis. (IF 2.0) Pub Date : 2023-10-04 Kei Nabeshima, Shingo Asakura, Ritsuko Iwata, Hisako Honjo, Atsushi Haga, Koichi Goka, Manabu Onuma
We developed a method to determine the sequences of hemagglutinin (HA) and neuraminidase (NA) from RNA extracted directly from wild bird fecal samples, using Nanopore Flongle. We determined the nucleotide sequences and subtypes of HA and NA in 16 and 15 samples respectively, using Flongle. The results of HA and NA subtyping determined by the conventional method were consistent with their subtypes determined

Dirofilaria immitis in pet dogs from the metropolitan area of the Colombian Caribbean Comp. Immunol. Microbiol. Infect. Dis. (IF 2.0) Pub Date : 2023-09-18 Maria A. Badillo-Viloria, Ignacio García-Bocanegra, Rodrigo J. de Lavalle-Galvis, Remigio Martínez, Steffania de la Rosa-Jaramillo, Adriana Castillo-Castañeda, Juan D. Ramírez, David Cano-Terriza
A cross-sectional study was carried out to determine the frequency and factors associated with infection in pet dogs in the metropolitan area of the Colombian Caribbean (northern Colombia). A total of 173 dogs were analyzed by a commercial rapid immunochromatographic test (RIT) and a nested PCR of the cytochrome oxidase subunit I gene, in parallel. Ninety-two (53.2%) of the dogs showed positive results
