Felis catus gammaherpesvirus 1 (FcaGHV1) and coinfections with feline viral pathogens in domestic cats in Brazil

ABSTRACT: Felis catus gammaherpesvirus 1 (FcaGHV1) may causes an asymptomatic infection that result in an efficient transmission and subsequently dissemination of the virus in feline population. This study used molecular detection by qPCR (quantitative PCR) based on DNA polymerase gene fragment amplification to evaluate the occurrence of FcaGHV1 and its correlation with other feline viral pathogens, such as Carnivore protoparvovirus 1 (CPPV-1), Felid alphaherpesvirus 1 (FeHV-1), and feline retroviruses such as feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV). Of the 182 blood samples evaluated 23.6% (43/182) were positives for FcaGHV1. Approximately 37.9% (33/87) of the samples that tested positive for retrovirus were also were positive for FcaGHV1 infection (P0.66) or CPPV-1 (P>0.46) coinfection. All samples were negative for FeHV-1. Male felines were significantly associated to FcaGHV1 (P
