Abstract: The normal uterine flora is dominated by lactobacilli which play a vital role in maintaining uterine health. During the part, the uterus is exposed to exogenous and endogenous infections causing a change in the uterine flora. In she-camels, the composition of the uterine microbiota after parturition remains poorly documented. The aim of this study was to investigate the kinetics of uterine bacterial flora after calving coupled with hormonal dosage. Uterine swabs and blood samples were collected at 8, 15, 21, 28, 35, 42 days after the part. A total of 354 Gram-positive bacteria were identified, the catalase test showed that 80.2% were Staphylococci and 19.8% were Streptococci. Identification on the API galleries showed two Staphylococci (S. lentus and S. xylosus) and 15 Streptococci including 26.1% of Aerococcus (A. viridans 1, 2 and 3), 30.68% of Streptococcus (S. pyogenes, S. dysgalactiae ssp. Equisimilis, S. pneumoniae, S. bovis, S. uberis, S. mitis 1), 13.02% of Enterococcus (E. faecium, E. faecalis, E. avium), 8.4% of Leuconostoc spp. and 21.60% of Lactococcus (L. lactis subsp lactis, Lactococcus lactis subsp cremoris). Progesterone has a positive effect on the proliferation of Staphylococci and Streptococci (p<0.05-0.001) while 17β Oestradiol has a negative effect (p<0.05). These last homo-fermented acidophilic species which produce lactic acid, seem to strengthen uterine defence during the postpartum period in she-camels.
