Abstract
In Egypt, Parasitic blood diseases (Babesiosis & Theileriosis) in cows and buffaloes have been reported as one of the major causes of serious economic losses, and the occurrence of these diseases in cows and buffaloes is considered by many workers as one of the most dangerous diseases which affect the animal
industry.
The problem becomes more serious and more complicated if the animals were suffering from bacteriological infections in addition to parasitic blood diseases.
The present study was carried out to investigate the bacteriological infections that may accompany parasitic blood
diseases.
Examination of blood smears stained with Gimsa stain of 60 cases (41 cows and 19 buffaloes) suffering from parasitic blood diseases (Babesiosis & Theileriosis) revealed that 28 cows & 11 buffaloes were suffering from Babesiosis, while 13 cows & 8 buffaloes were suffering from Theileriosis.
Animals suffering from Babesiosis were found to be infected with mastitis with percentage of 15.38%, endometritis and cervicitis with percentage of 17.94% and other pyogenic
infections with percentage of 66.6%.
Animals suffering from Theileriosis were found to be infected with mastitis with percentage of 19.04%, endometritis and cervicitis with percentage of 28.57% and other pyogenic infections with percentage of 52.38%.
The results of bacteriological examination of 10 mastitis milk samples, 13 vaginal mucous discharge and 37 pus samples which were collected from parasitic blood diseased animals revealed that 5 different species of bacteria could be isolated.
Isolated strains were identified by using different sugar fermentation tests and different biochemical reaction. Also specific media and tests were applied for confirmation.
Staphylococcus and streptococcus were the most common contagious bacteria isolated. These two species of bacteria were isolated for 35 and 20 times respectively. Thus it was concluded that these two types play an important role in increasing complications of parasitic blood diseases.
Escherichia coil strains were isolated for 15 times either alone or in mixed infection. This organism belongs to the cow’s environment which differs from contagious one in that Escherichia coil exist in cow’s environment by faecal
contamination. So it is difficult to eliminate it from cow’s environment.
The previously mentioned 3 species of bacteria showed to be the
most prevalent microorganisms isolated from animals with Babesiosis and Theileriosis.
Actinomyces pyogenes were isolated 13 times from total bacterial
isolates while Baciffus anthracoidwere isolated 17 times.
from the present study we can concluded that Babesiosis and Theileriosis are serious problems that face animal industry. Those problems are complicated by other bacterial infections and threaten the animal life.
So we recommended that:
1.Early diagnosis of blood parasites by blood smear examination is a good tool for controlling babesiosis and theileriosis by treatment.
2.Good hygienic measures minimize complications resulting from bacterial infections.
