Study on Clinical Mastitis (Bacteriological) in She-Camels (Camelus dromedarius) in Some Areas of Middle Euphrates in Iraq

Abstract

The lack of information about mastitis in camels in Iraq has stimulated this research in desert lands of AL-Najaf and Al-Qadissiya provinces. The study is concerned with determining the overall infection, percentage of clinical mastitis according to age, stages of lactation and the number of calving, as well as detection the susceptibility of isolated microorganism to the antimicrobial drugs. 402 quarters of 141 lactating she-camels were examined.Result of this study show that percentage of clinical mastitis was 5.22 % and 11.35% for quarters and animals respectively. 23.81% and 18.75% of quarters and animals respectively were showed acute form of mastitis, whereas 57.15% and 56.25% which identified as chronic form for quarters and animals respectively, also result showed that 19.04% samples identified as bland teats.Gram positive bacterial isolates was (76.19%) including Staphylococcus aureus, Staphylococcus hycus, Streptococcus agalactiae , Micrococcus luteus, Arcanobacterium pyogenes, whereas gram negative bacterial isolates was (23.8%) which included Mannhiemia haemolytica Salmonilla spp and, Klibcilla pneumonia. The results of study showed that varieties of ages and number of calving were not significant differences (≤ 0.01) on clinical mastitis in Iraqi she-camels.Antimicrobial drugs against bacterial isolates showed high susceptibility to Ciprofloxacin, Doxycycline, sulphthazin/Trimethiprim, Gentamicin, and Tetracycline, others antimicrobial Chloramphenicol, and Streptomycin showed moderate sensitivity, while all bacterial isolates were found resistant to Ampicillin, Erthromycine and Trimethiprime
