A multiplexed RT-PCR assay for nanopore whole genome sequencing of Tilapia lake virus (TiLV) por Delamare-Deboutteville, Jerome, Meemetta, W., Pimsannil, K., Sangpo, P., Han Ming Gan, Mohan, Chadag V., Ha Thanh Dong, Senapin, S.

“…By using this approach, we have recovered and assembled 10 TiLV genomes from total RNA extracted from naturally TiLV-infected tilapia fish, concentrated tilapia rearing water, and cell culture. Our phylogenetic analysis, consisting of more than 36 TiLV genomes from both newly sequenced and publicly available TiLV genomes, provides new insights into the high genetic diversity of TiLV. …”

Molecular detection and characterisation of potentially new Babesia and Theileria species/variants in wild felids from Kenya por Githaka, Naftaly W., Konnai, S., Kariuki, E., Kanduma, Esther G., Murata, S., Ohashi, K.

“…Reverse line blot with probes specific for Babesia spp. of felines indicated the presence of new Babesia species or genotypes in the lions and leopards, and unknown Theileria sp. in the cheetahs. Phylogenetic analyses using partial sequences of 18S ribosomal RNA (18S rRNA) gene showed that the parasite infecting the lions belong to the Babesia canis complex, and the parasite variant detected in the leopards clusters in a clade bearing other Babesia spp. reported in wild felids from Africa. …”

Cryptosporidium species detected in calves and cattle in Dagoretti, Nairobi, Kenya por Kang'ethe, Erastus K., Mulinge, E.K., Skilton, Robert A., Njahira, Moses N., Monda, J.G., Nyongesa, C., Mbae, C.K., Kamwati, S.K.

“…Twenty-five samples (20 %) were PCR-positive for Cryptosporidium, and 24 of the PCR products were successfully cloned and sequenced. Sequence and phylogenetic analysis identified 17 samples (68 %) as Cryptosporidium parvum-like, four samples (16 %) as Cryptosporidium ryanae, three samples (12 %) as Cryptosporidium andersoni and one sample (4 %) as Cryptosporidium hominis. …”

Genetic diversity and differentiation of Mongolian and Russian yak populations por Xuebin, Q., Han Jianlin, Lkhagva, B., Chekarova, I., Badamdorj, D., Rege, J.E.O., Hanotte, Olivier H.

“…The results showed that yak populations in Mongolia and Russia have maintained high genetic diversity within populations and a low, although significant, genetic differentiation between populations. Both phylogenetic and principal component analyses support a close genetic relationship between the Gobi Altai, south Gobi and north Hangai populations, and between the Hovsgol and Buryatia populations respectively. …”
