The Extent Response of Bacteria Isolated from Cases of Acute, Subacute and Chronic Mastitis in Iraqi Camels to some Antibiotics used in Treatment

Abstract

Our study was carried out on (75) dairy camels, aged (7-22) years, from Iraqi camels for each of the governorates (Babylon-Karbala-Al-Qadisiyah) with (25) camels from each governorate for the time period 1/6/2021 until 1/12/2022 to isolate and diagnosis the bacteria causing acute, subacute and chronic mastitis in camels, examining their sensitivity to common antibiotics used in treatment. The results of the study showed that the number of camels infected with mastitis for all types was (51) camels with a rate of (68%) out of a total of (75) milking camels, and the number of healthy camels was (24) with a rate of (32%). The number and percentage of subacute mastitis was (26) with a rate of (35%), acute mastitis (10) with a rate of (13%), and chronic mastitis (15) with a rate of (20%). As for the results of mastitis on the basis of inflammation tests for each quarter of the udder, the highest rate was in two quarters, where the percentage of infected camels was (35%), while the lowest percentage of infection was in four quarters or the whole udder with a rate of (18%). Results of bacteriological culture of milk samples of camels infected with mastitis, which numbered (306) samples. The highest percentage of isolates recorded was of C.N. Staphylococci by (35.62%), while the percentage of Staph.sciuri, Staphylococcus aureus and Staph.epidermidies respectively was (16.66%), (13) and (10.13%). The percentage of Streptococcus agalactia, Pasteurella haemolytica, Arcanobacterium pyogenes and E. coli respectively (10.45%), (6.2%), (5%) and (2.94%). The results of the sensitivity and antibiotic resistance examination, we show that there is statistical significant difference at the level of p ≥ 0.05 between the groups of the ages of camels.
