Whole-genome sequence data of a Salmonella enterica serovar Rissen sequence type 8877 isolated from cracked table egg in Sudan.

Salmonella enterica serovar Rissen is an emerging and important Salmonella serovar prevalent in live animals and foods from retail markets worldwide. Here, we describe the whole-genome sequence of Salmonella enterica Serovar Rissen Sequence Type 8877 isolated from a cracked table egg in Sudan. The whole-genome sequencing was obtained using Illumina Miseq platform. The quality of the sequenced read, the De novo assembly, and the sequencing typing was conducted by JEKESA pipeline (https://github.com/stanikae/jekesa). The assembled genome was also uploaded to the Center for Genomic Epidemiology web server to determine acquired antibiotic resistance genes, predict the serovar, and the antigenic profile. The genome of Salmonella enterica serovar Rissen 1-M1 was found to harbor 4,689 protein-coding genes, 96 RNA genes, and 115 pseudogenes, as predicted by NCBI Prokaryotic Genome Annotation Pipeline. This whole genome shotgun project has been deposited at DDBJ/ENA/GenBank under accession JAPSFB000000000.

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 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 conclusionThe prevalence of the strain was 4.73%, with significant differences between collection seasons and locations of wounds. A highly significant association between doses (105 CFU/ml, 102 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.
