We detected 93.6% of plasmids belonging to incompatibility (Inc) group HI1. Typhi isolates were related to the existence of plasmids. Typhi isolates with plasmids to Escherichia coli K12F strain devoid of plasmids.Īpproximately 79.6% of the MDR S. Antibiotic resistance phenotypes were conjugally transferred from S. Plasmid incompatibility grouping was established by PCR replicon typing using 18 pairs of primers to amplify FIA, FIB, FIC, HI1, HI2, I1-Iγ, L/M, N, P, W, T, A/C, K, B/O, X, Y, F and FIIA replicons. Typhi isolates based on alkaline lysis technique. Plasmids were extracted from 98 multidrug resistant S. Typhi) isolates from our previous study and consequently determined their incompatibility groups and possibility of conjugation transmission. We detected the presence of plasmids in multidrug resistant Salmonella enterica serovar Typhi (S. Plasmids harbour antibiotic resistance genes which contribute to the emergence of multidrug resistant pathogens. This has now becomes the one of the greatest challenges in the treatment and management of this disease. The emergence of multidrug resistance had made the treatment and management of enteric fever complicated. typhi developed resistance to several antibiotics like ampicillin, ceftriaxone, and co-trimoxazole, besides ciprofloxacin is at the developing resistance stage. Despite the discovery of newer antibacterial drugs, enteric fever has continued to be a major health problem. The bacteria can be distinguished by no gas production from other Enterobacteriaceae by growing in Triple Sugar Iron agar. The best diagnosis can be attained including cultural characterization on MacConkey and S-S agar, XLD agars, and the bacterium is strictly non-lactose fermenting. Currently, 107 strains of this organism have been isolated carrying variable metabolic characteristics, levels of virulence, and multi-drug resistance genes that make the treatment more complicated in the drug resistant regions. Although, the global burden of typhoid fever has reduced, emergence of multidrug resistant S.typhi (MDRST) is still a threat to public health. Typhoid fever is a systemic disease and without taking care, the illness may last for three to four weeks or death can be possible. S.typhi is a motile, non-capsulated, non-sporulating, Gram-negative facultative anaerobic bacillus, having characteristic flagellar, somatic, and outer coat antigens that are susceptible to various antibiotics. Typhoid is one of the major emerging public health problems in developing countries. Salmonella typhi is a facultative intracellular pathogen of Salmonella serovar that causes typhoid fever in humans (the only known natural hosts and reservoir of infection). Further molecular analysis needs to be conducted to examine the single isolate that carried the 933 bp fragment. The isolate was also found to be resistant to amoxicillin and fluoroquinolone according to a sensitivity test. Salmonella Typhi H58 PCR results showed that one (3.7%) of 27 isolates carried a positive fragment of 993 bp that led to the H58 strain, since the deletion flanks this fragment. The lowest drug sensitivities were to amoxicillin, at one (3.7%) of 27 isolates, and ampicillin, at 13 (48.1%) of 27 isolates. All 27 isolates were found to be sensitive to sulfamethoxazole/trimethoprim. We found 7% (27/367) of the samples to be positive by both blood culture and PCR. All of the confirmed samples were tested for susceptibility against antibiotics and molecularly analysed for MDR H58 existence using a simple PCR technique. The blood sample was cultured, then confirmed via simple PCR. A total of 367 blood samples of typhoid fever patients were collected from April 2018 until April 2019. We aimed to analyse the existence of Salmonella Typhi MDR H58 in patients with typhoid fever in Makassar, Indonesia. This is conducted considering the detection of Salmonella Typhi strains that have been carried out so far are only using antimicrobial sensitivity tests to determine microbial resistance phenotypically and to determine genotypically using complex molecular techniques. MDR strain detection is needed by using a simple PCR technique that only uses a pair of primers. The surveillance of multidrug-resistant (MDR) H58 typhoid is highly important, especially in endemic areas.
