Abstract

SUMMARY

Feline neutrophils (PMN) were isolated and exposed to ultraviolet light-inactivated feline leukaemia virus (UV-FeLV) and purified envelope component pl5E (FeLV- pl5E). Functional capacity of exposed PMN was measured utilizing the chemiluminescence (CL) response. PMN exposed to UV-FeLV demonstrated depressed CL responses to Ca-ionophore A23187 and latex particles. However, FeLV-pl5E produced significant suppression in the CL response to A23187 but failed to produce significant alterations in response to latex particles. The data indicate that FeLV-pl5E may, in part, be responsible for increased morbidity and mortality among FeLV-infected cats through suppression of the PMN population.
