Abstract
The occurrence of CF-antibodies, SN-antibodies against FMD
V. Type 01’ /2/72-Egypt and VIA-antibodies,in serum samples
collected from different species of farm animals in Sharkia
province indicate FMD to be wide spread. As vaccin ation is
limitted only to cattle and hi ffaloes populations at governmental
farms, The antibodies in sheep, camels and cattle from private
farms have been developed by nature exposure of these animals
to the field strain of virus. The Virus Infections Associated (VIA)
Antigen test proved to be the most useful in detection of infec-
tion, although VIA negative animals also had ser um-rieut ra hz ing
antibodies.
2- The survival time of FMDV strain 01/2/72-Egypt in the faeces
soil, and sewage has been studied daily for periods upto 8 days.
a-Infected faeces kept inside doors (at room temp.) lost
nearly its virus content within 7 days from the time of

TCID50/ml, the same remaining titre was left but
within a short period (5 days) when the infected faecal
sample was kept outside doors (in the open atmosphere).
b- In the soil the same strain of FMDV lost its infectivity
within 4 days post-infection. The remaining infective titre
after 4 days p. i. were 1 and 0.75 10glO TCID50/ml. for
those samples kept inside and outside doors respectively.
c- In sewage, the strain 01/2/72-Egypt survived for 4 days
