Feline leukemia virus infection
3. Introduction
Feline leukemia virus (FeLV) is a retrovirus that infects cats. As a retrovirus, FeLV is transmitted as an RNA virus but the RNA is reverse transcribed into DNA. Retroviruses contradict the Central dogma of molecular biology. FeLV is usually transmitted between infected cats when the transfer of saliva or nasal secretions is involved. If not defeated by the animal’s immune system, the virus can be lethal. The disease caused by this virus is a form of cancer of blood cells called lymphocytes (a leukemia).

Cats infected with FeLV can serve as sources of infection. Cats pass the virus between themselves through saliva and close contact, by biting another cat, through a litter box or food dish used by an infected cat (rarely happens), and from milk during nursing. Transmission can also take place from an infected mother cat to her kittens, either before they are born or while they are nursing.

The signs and symptoms of infection with feline leukemia virus are quite varied and include loss of appetite, poor coat condition, infections of the skin, bladder and respiratory tract, oral disease, seizures, lymphadenopathy (swollen lymph nodes), skin lesions, fatigue, fever, weight loss, stomatitis, gingivitis, litter box avoidance, pancytopenia, poor grooming, reoccurring bacterial and viral illnesses, anaemia, diarrhoea, and jaundice (Wiki: Feline leukemia virus).

1. ALVAC-FL- env/gag
a. Vaccine Ontology ID:
VO_0004740
b. Type:
Recombinant vector vaccine
c. Status:
Research
d. Host Species for Licensed Use:
Baboon
e. Gene Engineering of env from FeLV-A/Glasgow
  • Type: Recombinant vector construction
  • Description: Two ALVAC (canarypox virus)-based recombinant viruses expressing the feline leukemia virus (FeLV) subgroup A env and gag genes were assessed for their protective efficacy in cats. Both recombinant viruses contained the entire gag gene. ALVAC-FL also expressed the entire envelope glycoprotein, while ALVAC-FL(dl IS) expressed an env-specific gene product deleted of the putative immunosuppressive region (Tartaglia et al., 1993).

f. Gene Engineering of gag
  • Type: Recombinant protein preparation
  • Description: Two ALVAC (canarypox virus)-based recombinant viruses expressing the feline leukemia virus (FeLV) subgroup A env and gag genes were assessed for their protective efficacy in cats. Both recombinant viruses contained the entire gag gene. ALVAC-FL also expressed the entire envelope glycoprotein, while ALVAC-FL(dl IS) expressed an env-specific gene product deleted of the putative immunosuppressive region (Tartaglia et al., 1993).

g. Preparation
Two ALVAC (canarypox virus)-based recombinant viruses expressing the feline leukemia virus (FeLV) subgroup A env and gag genes (Tartaglia et al., 1993).
h. Immunization Route
Intramuscular injection (i.m.)
i. Cat Response
  • Vaccination Protocol: Cats were vaccinated with ALVAC-FL(dI IS) or ALVAC-FL, consisting of two subcutaneous inoculations of 10^8 PFU at 5 and 2 weeks prior to challenge (Tartaglia et al., 1993).
  • Vaccine Immune Response Type: VO_0003057
  • Challenge Protocol: All cats were challenged by oronasal administration of 2 x 10^6 FFU of FeLV-A/Glasgow-1 isolate to simulate natural transmission (Tartaglia et al., 1993).
  • Efficacy: Although only 50% of the cats vaccinated with ALVAC-FL(dl IS) were protected against persistent viremia after oronasal exposure to a homologous FeLV isolate, all cats administered ALVAC-FL resisted the challenge exposure. Significantly, protection was afforded in the absence of detectable FeLV-neutralizing antibodies (Tartaglia et al., 1993).
