| description | Feline leukemia virus (FeLV) belongs under the genus Gammaretrovirus and is
associated with a wide range of clinical signs worldwide. Sofar, the first and only
molecular characterization of local FeLV isolates performed in 2014 revealed that local
isolates to be closely related to UK isolate. Due to limited coverage of the study and the
nature of the virus that typically integrates the DNA into the host genome and undergoes
mutation, study on the current status of FeLV infection is necessary. Therefore, this
study aim to detect FeLV antigen in clinically ill cats by RT-PCR and to compare the currently identified variant similarity with previous related virus isolates from Malaysia
and other geographical distribution. By using convenience sampling method, plasma
and saliva were collected from 15 clinically ill cats and 5 healthy cats from Gasing
Veterinary Hospital. Viral nucleic acid was extracted and subjected to One-Step RT
PCR with specific primer targeting the highly conserved U3LTR and partial gag
regions. Two cats were tested positive for the antigen from the clinically ill group.
Partial nucleotide sequencing and phylogenetic analysis revealed that the current variant
are found to be 93-99% homologous to the previous Malaysian isolates and is still
closely related to UK isolate. Interestingly, they were also found to be closely related to
isolates from Japan. In conclusion, this study highlights the possibilities of evolutionary
relations between FeLV from Malaysia with FeLV of UK and Japan. |
