ABSTRACT

Aelurostrongylus abstrusus lives in the respiratory bronchioles and alveolar canals in the lungs of the cat and causes parasitic pneumonia. In present study, the effect of different temperatures on the viability of first stage larvae in feces of cats naturally infected with A. Abstrusus was investigated. Feces of cats were divided into two portions. One portion was left at room temperature (21-24°C) and the other, left at +4°C for three month-period. The fecal samples were examined by Baermann and McMaster techniques at 15 day-intervals. The number of living first stage larvae detected gradually decreased. The latest time of live larvae found in faeces left at room temperature was the 45th day and at +4°C, the 60th day.
