Parasite prevalence in free-ranging farm cats,Felis silvestris catus

SUMMARYNo animals tested were positive for feline leukaemia virus antigen andChlamydia psittaciantibodies, but all were positive for antibodies to feline calicivirus (FCV), feline herpesvirus 1 (FHV1) and rotavirus. They had antibodies to feline parvovirus (96%), feline coronavirus (84%) and cowpox virus (2%). Antibody to feline immunodeficiency virus (FIV) was found in 53% of animals, which were less likely to be infected withHaemobartonella felis, and had higher FHV antibody titres than cats without FIV. FCV was isolated from 51% cats and FHV1 and feline reovirus each from 4%.H. feliswas present in 42% of animals, and antibody toToxoplasma gondiiin 62%. Clinical abnormality had a significant association with FIV and feline calicivirus infections, but sex, age, social status and feeding group had no significant association with prevalence of any parasites.Toxocara catiandToxascaris leoninaeggs were found, respectively, in 91% and 82% of animals tested.

Feline Leukaemia Virus

Objectives Currently, there are only a few studies on how immunocompromised cats, such as cats infected with feline leukaemia virus (FeLV) and feline immunodeficiency virus (FIV), respond to vaccination. Therefore, this study measured feline panleukopenia virus (FPV) antibodies in retrovirus-infected cats within a period of 28 days after FPV vaccination, and compared the immune response to that of non-infected cats. Methods Eight asymptomatic retrovirus-infected cats (four FeLV, four FIV), and non-infected age-matched control cats (n = 67) were vaccinated with a commercial FPV modified live virus (MLV). Pre- and post-vaccination antibody titres were measured by haemagglutination inhibition (HI) on days 0, 7 and 28. An HI titre ⩾1:40 was defined as protective. An adequate response to vaccination was defined as a four-fold titre increase or higher. Comparison of the immune response of retrovirus-infected and non-infected cats was performed. Results Pre-vaccination FPV antibody titres ⩾1:40 were present in 100% (n = 8/8; 95% confidence interval [CI] 62.8–100) of retrovirus-infected and in 77.6% (n = 52/67; 95% CI 66.2–86.0) of non-infected cats. An adequate response to vaccination (titre increase ⩾four-fold) was seen in 1/8 retrovirus-infected cats (12.5%; 95% CI 0.1–49.2) compared with 22/67 non-infected cats (32.8%; 95% CI 22.8–44.8). In cats with high pre-vaccination titres (⩾1:160), a four-fold titre increase or higher was observed in 1/8 retrovirus infected cats (12.5%; 95% CI 0.1–49.2) compared with 4/42 non-infected cats (9.5%; 95% CI 3.2–22.6). None of the eight retrovirus-infected cats developed illness or vaccination side effects after vaccination with MLV against FPV within the 28 days. There were no significant differences between groups: for pre-vaccination titres; for at least four-fold titre increases following vaccination in either all cats or the cats with high pre-vaccination titres; and concerning adverse effects. Conclusions and relevance All retrovirus-infected asymptomatic cats had pre-vaccination FPV antibodies indicating protection against panleukopenia. Response of retrovirus-infected cats to vaccination was similar to the response of non-infected cats.

Feline haematology profiles of patients presented to the University of Bristol Small Animal Hospital from January 2000 to October 2005 were evaluated for thrombocytosis (defined as a platelets count of >700×109/l and confirmed on smear evaluation). Thrombocytosis was found in 79 cats (4.64% of the hospital feline population), with values ranging from 703 to 1895×109/l. Signalment, clinical presentation, concurrence of other haematological abnormalities, diagnoses and outcome were evaluated in 51 cases in which complete medical records were available. Other variables (feline immunodeficiency virus/feline leukaemia virus status, thyroxine level, haemoplasma PCR, toxoplasma antibody titres) were also evaluated. No association was found between the presence of thrombocytosis and breed or gender. Gastrointestinal signs were the most common clinical presentation. Lymphopenia was the most common concurrent haematological abnormality. Based on final diagnosis reached, cats were grouped both according to the DAMNITV classification and according to the body system affected. Amongst the DAMNITV classification, inflammatory/infectious conditions were most commonly associated with thrombocytosis. According to body systems, gastrointestinal involvement was most represented, followed by endocrine cases. No association was found between the severity of thrombocytosis and outcome.

Objectives Feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV) are immunosuppressive viruses in cats that increase their susceptibility to zoonotic pathogens. This study aimed to determine the occurrence of one or both viruses, the risk factors associated with infection, and to develop further recommendations. Methods This was a cross-sectional study conducted at the Veterinary Faculty of Eduardo Mondlane University, Mozambique, between March and December 2017, in 145 cats. From each of 145 cats, we took 1.5 ml of blood by jugular puncture for detection of antibodies to FIV and FeLV antigens in whole blood using a commercial test kit, DFV Test FeLV/FIV. Results We found an overall prevalence of 11.0% and 14.5% for FIV antibodies and FeLV antigens, respectively, with four (2.8%) cats coinfected by both pathogens. Male cats were more likely to be infected with FIV (odds ratio [OR] 1.1, 95% confidence interval [CI] 0.3–4.0) compared with female cats. Clinically ill cats were more likely to have a positive result for FeLV antigen infection (OR 18.8, 95% CI 5.2–68.3). Moreover, cats living in suburban areas have a greater chance of a positive result for FeLV infection (OR 3.7, 95% CI 1.4–9.6) compared with cats living in urban areas. Conclusions and relevance FIV and FeLV occur in cats from Maputo and possibly all over the country. Further studies should be conducted in Mozambique and other African countries to define the burden of both pathogens in cats, coinfection with other zoonotic pathogens and the possible role played by the cats on the transmission of zoonotic and opportunistic diseases to humans.

Viral Preparation

Abstract Typical C-type oncorna virus particles as shown by electron microscopy have been purified from the supernatant of cultured lymphocytes from bovine leukosis. In the purified C-particle fraction a DNA-polymerase activity was detected. Using several synthetic RNA-or DNA-homopolymers and 70S Friend virus RNA the template response of this bovine leukosis cell particle DNA polymerase was compared with those of feline leukaemia virus DNA polymerase and DNA polymerase from normal bovine lymphocytes. The DNA polymerase detected in the viral preparation of bovine leukosis is suggested to be an oncorna-virus-specific enzyme.
