Abstract
The present study was conducted on 500 cattle of
different breed in Giza governorate. Their age
ranged from 1-7 years of different sexes. All
suspected animals were clinically examined. The
recoded lesions including the complicated cases in
different age and sexes were described. The
infected animals were classified according to the
severity of clinical status into mild and severe
forms. The severe form was recorded in all ages
and both sexes in the frezian cattle and some of
the native ones while the mild form was recorded
in native cattle.The morbidity, mortality and case
fatality rates of LSD among examined Egyptian
cattle were 100%, 1.8%, and 1.8% respectively.
Grossly lumpy skin lesions appeared as nodules 1
to 7 cm in diameter and occurred anywhere on the
animal body. The hair stands erected over early
skin lesions. The nodules involved the epidermis,
dermis, and subcutaneous tissue and may even
spread to the musculature. Histopathological
examinations of lumpy skin disease revealed
ballooning degeneration of stratum spinosum with
microvesicles formation. Eosinophilic
intracytoplasmic inclusion bodies specific for LSD
were detected by electron microscopy. The main
target of treatment trials was to save the animal
life and to prevent LSD complications.
