Abstract The proposed research outlines a serious common concern of Salmonella resistance to antimicrobials following prolonged exposure to the disinfectants (biocides). These phenotypes of bacteria could potentially result in hard to treat infections. Typical for avian sources, biocide sensitive S. enterica subsp. enterica serovars: Typhimurium, Enteritidis, Virchow and Zanzibar and their isogenic biocide-tolerant variants were studied in order to investigate bacteriostatic effect of two commercially available biocide formulations: potassium peroxymonosulfate (P) and dodecylamine based structure (triamine, D). We found that cultivating of the bacteria in the medium supplemented with a blend containing P did not influence their antibiotic susceptibility pattern. In contrast, tolerance of bacteria to D compound resulted in resistance to co-trimoxazole, cefotaxime and ciprofloxacin of which two cefotaxime and ciprofloxacin are used commonly for the treatment of invasive Salmonella infections in humans. The dependency between OMP patterns and the level of Salmonella survival in media containing the biocides was observed merely in serovar Typhimurium. In conclusion, these results suggest that Salmonella strains challenged by prolonged treatment with the disinfectants become resistant to antibiotics, however it depends on Salmonella serovar and the chemical used. This paper also highlights the loop-mediated isothermal amplification (LAMP) as a technique that offers great benefits to microbiological detecting of Salmonella species in the samples.

Drug Of Choice

Background: Methicillin resistant Staphylococcus aureushas emerged as one of the most important nosocomial pathogens. It invokes a tremendous financial burden and enhanced morbidity and mortality due to difficult to treat systemic infections.Aim of this study was to determine antibiotic susceptibility pattern of Staphylococcus aureus and Methicillin resistant Staphylococcus aureus. Materials and Methods: Different clinical specimens were collected and processed for routine culture and antibiotic sensitivity test by standard microbiology techniques. Results: Out of 1173 samples received for microbiological examination, 100 were found to be S. aureus with 19% cases were Methicillin resistant Staphylococcus aureus (MRSA). Fourteen MRSA were found from inpatient and 5 were from outpatient. MRSA was found higher in female than male and maximum number (31.5%) was found in age group 0-10 years. Staphylococcus aureus was 100% sensitive to Vancomycin followed by Amikacin (90%), Gentamycin (83%), and tetracycline (81%). On urine isolates Nitrofurantoin(91.6%) was drug of choice. All the isolates were resistant to Penicillin G. In case of Methicillin resistant Staphylococcus aureus showed 100% sensitive to Vancomycin followed by Amikacin (84.2%), Tetracycline (63.1%), Ciprofloxacin (42%) and Gentamycin (36.8%). Among urine isolates Nitrofutantoin showed 87.5% sensitive followed by Norfloxacin (75%). Conclusion: Methicillin resistant Staphylococcus aureus was found 19% of Staphylococcus aureus isolates. It was most common in females, hospitalized patients and young age group. Vancomycin seems to be drug of choice followed by Amikacin. It would be helpful to formulating and monitoring the antibiotic policy and ensure proper empiric treatment.

Susceptibility Tests

Antibiotics to treat dental caries infection are routinely prescribed which led to the increased resistance against bacteria. The purpose of this investigation was to perform antibiotic susceptibility tests on a panel of pathogenic bacteria isolated from dental caries infection. Bacteria were isolated from caries site of patients and identified at the species level. Each of 150 species of bacteria was tested for antibiotics susceptibility to a five antibiotics using Etest. The antibiotics used were Amoxicillin, Cloxocillin, Erythromycin, Tetracycline and Penicillin‐V. The obtained resistance percentage for each antibiotic were Penicillin V: 72/150 (48%), Tetracycline: 99/150 (66%), Amoxicillin: 135/150 (90%), Cloxocillin: 117/150 (78%), and Erythromycin: 90/150 (60%) (Table 1). In case of combinatorial antibiotic exposure, the resistance percentage of Penicillin V/Amoxicillin and Amoxicillin/ Erythromycin was 39/150 (26%), and 45/150 (30%) respectively. The study has well demonstrated the clinical picture of antibiotic resistance and susceptibility pattern of bacteria causing dental caries. The obtained comprehensive data will allow investigating the spatial distribution of pathogenic, antibiotic resistant bacteria among dental caries patients which further may help into development of novel diagnostic and treatment approaches for the same.
