Susceptibility pattern of Salmonella enterica against commonly prescribed antibiotics, to febrile-pediatric cases, in low-income countries.

ABSTRACT:

Background

In most low-income countries, febrile-pediatric-cases are often treated empirically with accessible antibiotics without periodic epidemiological surveillance, susceptibility testing, or minimal lethal dose calculations. With this backdrop, the study was undertaken to evaluate the susceptibility trend of Salmonella enterica against the commonly prescribed antibiotics.

Methods

All isolates of Salmonella enterica were identified by standard protocols of biotyping and serotyping, then tested against antibiotics by the modified Kirby disk-diffusion method. Minimum Inhibitory Concentration (MIC) of isolates was determined by the agar-dilution method and compared with disk diffusion results and on nalidixic-acid sensitive/resistant strains.

Results

Among 1815 febrile-pediatric patients, 90(4.9%) isolates of Salmonella enterica [serovar: Salmonella Typhi 62(68.8%) and Salmonella Paratyphi A 28(31.1%)] were recovered. The incidence of infection was higher among males, age groups 5 to 9, and patients enrolling in the out-patient department (OPD). On the disk-diffusion test, most isolates were sensitive against first-line drugs i.e.cephalosporins, and macrolides. However, against quinolones, a huge percentile 93.3%, of isolates were resistant [including 58 Typhiand 26 Paratyphiserovar] while nearly 14% were resistant against fluoroquinolones. When MICs breakpoint were adjusted as follows: 4??g/ml for azithromycin, ?1??g/ml for ciprofloxacin, 2??g/ml for ofloxacin, 8??g/ml for nalidixic acid, and 1??g/ml for cefixime, higher sensitivity and specificity achieved. Compared to other tested antibiotics, a low rate of azithromycin resistance was observed. Nevertheless, higher resistance against fluoroquinolones was observed on NARS strain.

Conclusion

Higher susceptibility of Salmonella enterica to the conventional anti-typhoidal drugs (amoxicillin, chloramphenicol, cotrimoxazole, cephotaxime) advocates for its reconsideration. Although, the lower susceptibility against fluoroquinolones among nalidixic-acid-resistant Salmonella (NARS) strain negates its empirical use among the study age group.

Project description:BackgroundNon-prescription dispensing of antibiotics, one of the main sources of antibiotic misuse or over use, is a global challenge with detrimental public health consequences including acceleration of the development of antimicrobial resistance, and is facilitated by various intrinsic and extrinsic drivers. The current review aimed to systematically summarise and synthesise the qualitative literature regarding drivers of non-prescribed sale of antibiotics among community drug retail outlets in low and middle income countries.MethodsFour electronic databases (PubMed, CINAHL, Scopus and Google Scholar) and reference lists of the relevant articles were searched. The Joanna Briggs Institute's Critical Appraisal Checklist for qualitative studies was used to assess the quality of included studies. The enhancing transparency in reporting the synthesis of qualitative research statement was used to guide reporting of results. Data were coded using NVivo 12 software and analysed using both inductive and deductive thematic analysis.ResultsA total of 23 articles underwent full text review and 12 of these met the inclusion criteria. Four main themes were identified in relation to facilitators of non-prescribed sale of antibiotics among community drug retail outlets: i) the business orientation of community drug retail outlets and tension between professionalism and commercialism; ii) customers' demand pressure and expectation; iii); absence of or a lax enforcement of regulations; and iv) community drug retail outlet staff's lack of knowledge and poor attitudes about antibiotics use and scope of practice regarding provision.ConclusionsThis review identified several potentially amendable reasons in relation to over the counter dispensing of antibiotics. To contain the rise of antibiotic misuse or over use by targeting the primary drivers, this review suggests the need for strict law enforcement or enacting new strong regulation to control antibiotic dispensing, continuous and overarching refresher training for community drug retail outlet staff about antibiotic stewardship, and holding public awareness campaigns regarding rational antibiotic use.

Project description:ObjectiveThe gut microbiota influences many aspects of human health. We investigated the magnitude and duration of changes in gut microbiota in response to antibiotics commonly prescribed in UK primary care.MethodsWe searched MEDLINE, EMBASE and AMED, all years up to May 2020 including all study designs, collecting and analysing data on the effect of antibiotics prescribed for respiratory and urinary tract infections. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Cochrane standard methods. Risk of bias was evaluated using the Critical Appraisal Skills Programme. Narrative synthesis was used to report the themes emerging from the data.Main outcome measuresPrimary outcomes were antibiotic-induced changes in the composition and/or diversity of the gut microbiota. Secondary outcome was the time for the microbiota to return to baseline.ResultsThirty-one articles with low or unclear risk of bias showed that antibiotics impact the gut microbiota by causing rapid and diminished levels of bacterial diversity and changes in relative abundances. After cessation of treatment, gut bacteria recover, in most individuals, to their baseline state within a few weeks. Some studies suggested longer term effects from 2 to 6 months. Considerable heterogeneity in methodology makes the studies prone to biases and other confounding factors. Doxycycline was associated with a marked short-term decrease in Bifidobacterium diversity. Clarithromycin decreased the populations of Enterobacteria, and the anaerobic bacteria Bifidobacterium sp and Lactobacillus sp in numbers and diversity for up to 5 weeks. Phenoxymethylpenicillin, nitrofurantoin and amoxicillin had very little effect on the gut microbiome.ConclusionsDespite substantial heterogeneity of the studies and small sample sizes, there is evidence that antibiotics commonly used in primary care influence the composition of the gastrointestinal microbiota. Larger population-based studies are needed to fully understand how antibiotics modulate the microbiota, and to determine if these are associated with (longer term) health consequences.Prospero registration numberCRD42017073750.
