Abstract
This investigation was run in some villages in Assiut governorate
during summer 2007 to diagnose acute clinical mastitis in
different animal species and to apply different lines of treatment
for evaluating which treatment line of choice giving cure, aiming
to another goal by preventing the conversion of acute mastitis
towards the chronic one which is difficult to be treated and the
dairy animal will be excluded. Therefore, 2150 animals were
clinically examined in 5 villages located north to Assiut city,
Egypt, including 400 cows, 950 ewes and 800 she goats, and the
incidence of acute clinical mastitis was 22.50%, 2.63% and 4.63%,
respectively. Milk samples were collected from all clinically
mastitic cows for bacteriological examination to identify the
causative agents of the intra-mammary infection (IMI). It was
found the major causative agents isolated were Staphylococcus
aureus, Streptococcus
agalactiae, Escherichia
coli and Corynebacterium
pyogenes, causing either single or mixed type of infection.
When applying different lines of treatment, all diseased animals
were classified into 3 groups: 1st group received local treatment
by intra-mammary infusion antibiotic. 2nd group received
systematic treatment by intra-muscular (I/M) injection of both
antibiotic and anti-inflammatory drugs. While, 3rd group received
combination of both local and systematic treatment lines together.
Cure% was achieved as 50% for 1st group, 90% for 2nd group, while
3rd group gave complete cure by 100%. It was noticed that the
incidence of acute clinical mastitis among examined cows was
worrisome and can be considered as indicator of the epidemiology
of the disease. While, spreading of the disease among ewes and she
goats was somewhat low in comparison with that of cows. In
conclusion, combination of both local and systematic treatment
lines together should be advised in treatment of acute clinical
mastitis to ensure complete cure. The obtained results highlighted
the focus towards the spreading of acute clinical mastitis among
cows lived in some Assiut governorate villages.
Key words: Acute
clinical mastitis, Cows, Ewes, She goats, Intra-mammary infection
(IMI).
