A prevalence and molecular characterization of novel pathogenic strains of Macrococcus caseolyticus isolated from external wounds of donkeys in Khartoum State –Sudan
A pathogenic strain of Macrococcus caseolyticus (M. caseolyticus) was isolated from wounds infection during an investigation on donkeys in Khartoum State. (122) samples were collected from external wounds (head, abdomen, back and leg) during different seasons. One isolate (124B) was identified using...

description | A pathogenic strain of Macrococcus caseolyticus (M. caseolyticus) was isolated from wounds infection during an investigation on donkeys in Khartoum State. (122) samples were collected from external wounds (head, abdomen, back and leg) during different seasons. One isolate (124B) was identified using whole-genome sequence analysis. RAST software identified 31 virulent genes of disease and defense, including methicillin-resistant genes, TatR family and ANT(4′)-Ib. Plasmid rep22 was identified by PlasmidFindet-2.0 Server and a CRISPR. MILST-2.0 predicted many novel alleles. NCBI notated the genome as a novel M. caseolyticus strain (DaniaSudan). The MLST(−)tree(−)V1 revealed that DaniaSudan and KM0211a strains were interrelated. Strain DaniaSudan was resistant to ciprofloxacin, ceftazidime, erythromycin, oxacillin, clindamycin and kanamycin. Mice modeling showed bacteremia and many clinical signs (swelling, allergy, wounds, and hair loss). Enlargement, hyperemia, adhesions and abscesses were observed in many organs. Constructive conclusion The prevalence of the strain was 4.73%, with significant differences between collection seasons and locations of wounds. A highly significant association between doses (10(5) CFU/ml, 10(2) CFU/ml, Intra-peritoneum and sub-cutaneous) and swelling, developing of allergy and loss of hair (p = 0.001, p = 0.000 and p = 0.005) respectively were seen. This result represents the first report of pathogenic strains of M. caseolyticus worldwide.
