Lactobacilli are among the predominant microorganisms in the vaginal<br />

tract of some homoeothermic animals. The current investigation was<br />

designed to throw line on Lactobacillus in the vagina of buffaloescows.<br />

Vaginal <strong>and</strong> blood samples were collected from animals reared at<br />

Lower Egypt for a period of 2 years. Vaginal swabs were collected<br />

from buffalo-cows either showed normal ovarian activity or suffering<br />

from ovarian inactivity. Swabs were collected from each animal in<br />

either Tryptic soy broth for the routine bacteriological examination or<br />

De Man, Rogaso, Sharpe (MRS) for isolation of Lactobacillus. In vitro<br />

sensitivity <strong>and</strong> probiotic tests against the most predominant isolates<br />

isolated from buffalo cows (Y. enterocolitic, C. diversus, E. coli,<br />

Micrococcus spp., E. Faecalis, S. aureus <strong>and</strong> Bacillus spp. were carried<br />

out). Results showed that Lactobacillus was isolated from the vagina of<br />

normal cyclic buffalo-cows with an high incidence (90.91%) as<br />

compared to in animals suffering from ovarian inactivity (81.82%).<br />

Vaginal pH <strong>and</strong> the recovered isolates were recorded in relation to<br />

ovarian activity. Ciprofloxacin <strong>and</strong> ofloxacin are the most effective<br />

antibiotics followed by tobramycin, gentamicin <strong>and</strong> oxytetracycline.<br />

The resistant rate of isolates to some antibiotics was recorded. In vitro<br />

use of Lactobacillus isolated from the genital tract of normal buffalocows<br />

as probiotic against the most predominant isolates from buffalo<br />

cows suffering from ovarian inactivity revealed that L. acidophilus is<br />

the most effective strain followed by L. casei rhamnosus. It could be<br />

concluded that Lactobacillus is one of the normal bacterial floras of the<br />

vagina of buffalo-cows; L. acidophilus <strong>and</strong> L. casei rhamnosus were<br />

the most predominant isolates <strong>and</strong> showed high probiotic effect against<br />

the most predominant bacteria isolated from cases suffering from<br />

ovarian inactivity.<br />

Coccidiosis in buffalo species is a widespread protozoa infection<br />

caused by several species belonging to genus Eimeria <strong>and</strong> localized in<br />

the intestine. Higher values of prevalence <strong>and</strong> diarrhoeic<br />

manifestations are more frequently observed in young animals;<br />

however, subclinical coccidiosis is responsible for serious economic<br />

losses for reduction of growth rates <strong>and</strong> feed conversion in young<br />

animals. The objective of this field efficacy study was to demonstrate<br />

the effect of a treatment with Toltrazuril (Baycox Bovis ® ) <strong>and</strong><br />

Diclazuril (Vecoxan ® ) on buffalo calves naturally exposed to Eimeria<br />

infection, in terms of lack of faecal oocyst excretion <strong>and</strong> body weight<br />

gain. Two farms in Central Italy were selected based on previous<br />

history of coccidiosis outbreak by E. zuernii <strong>and</strong> E. bovis <strong>and</strong> on the<br />

presence of subclinical infections. A total of 135 buffalo calves ranged<br />

from 4 to 15 weeks of age <strong>and</strong> from 39 to 80 kg <strong>and</strong> positive for<br />

coccidiosis, were selected. The animals were divided in 3 distinct<br />

groups (T, D <strong>and</strong> C) of 30 (farm A) <strong>and</strong> 15 subjects (farm B), each<br />

based on population size of the farms. On day 0 the T group was treated<br />

with Toltrazuril (Baycox ® Bovis) at dose of 15 mg/kg body weight; the<br />

D group was treated with Diclazuril (Vecoxan ® ) at dose of 1 mg/kg<br />

body weight <strong>and</strong> the C group was kept as untreated control. The<br />

animals were examined for the presence of Eimeria species by qualiquantitative<br />

coprological tests at 0,2,4,7,49,51,53,56 days posttreatment.<br />

No side effects were observed in the medicated group during<br />

the trial. On day +7, Toltrazuril showed a mean efficacy value of 98.<br />

85%. High values of efficacy were observed till 42 days after treatment;<br />

on day 56 the mean value was of 65.37%. On day +7 Diclazuril showed<br />

a mean efficacy value similar but lower than Toltrazuril (97.28% versus<br />

98.85%); values > 50% were observed only till 23 days after the<br />

treatment. Statistical significant difference was observed between the<br />

animal of the T <strong>and</strong> D groups <strong>and</strong> the control group (p
