Distribution trends & antibiogram pattern of Salmonella enterica serovar Newport in India

Abstract

Background & objectives:Salmonellosis is a major public health concern worldwide. Besides typhoidal salmonellae, infections due to non-typhoidal serovars of Salmonella are also associated with high morbidity and mortality leading to huge economic losses. Among non-typhoidal serovars, Salmonella Newport has been reported as a major cause of foodborne infections resulting in outbreaks due to consumption of contaminated food items. Little data related to this serovar are available from India leading to the scarcity of information on the distribution trends of this important serovar in the country. Therefore, an effort was made in the present study to generate data on distribution trends and antibiogram of S. Newport in the country.Methods:S. Newport isolates received at the National Salmonella and Escherichia Centre at Kasauli, India, during January 2010 to December 2013 were analysed for their distribution trends and antibiogram data were also generated using standard methods.Results:In the present study, S. Newport isolates were received from eight States and one union territory of the country and highest proportion of S. Newport isolates were found to be from humans (53.61%) followed by animals (27.84%) and food (18.56%). S. Newport isolates exhibited resistance to all drugs used in the present study except chloramphenicol, ciprofloxacin and cefuroxime.Interpretation & conclusions:Considering distribution of this important serovar of Salmonalla and its wide range of reservoirs, steps towards formulation and execution of efficient surveillance programmes should be taken.

Acinetobacter baumannii Infection-Related Mortality in Hospitalized Patients: Risk Factors and Potential Targets for Clinical and Antimicrobial Stewardship Interventions

“…Patients with MDRAB infections had a high incidence of polymicrobial infections (88%) and chronic comorbidities (66%); these were likely the confounders contributing to increased mortality. Our finding matches many studies from different parts of the world; they found several folds increase in mortality rate in MDRAB infected patients than in those infected with susceptible phenotypes, as well as increased hospital and intensive care unit length of stay [ 34 , 35 , 36 ].…”

Drug resistance, AmpC-β-lactamase and extended-spectrum β-lactamase-producing Enterobacteriaceae isolated from fish and shrimp

“…These data are in agreement with findings in the literature, since strains isolated from fish have been showing resistance to this first-generation cephalosporin 32 , 33 . In addition, cefoxitin- and cefuroxime-resistant bacteria have also been isolated from food 34 , 35 .…”

Antimicrobial Resistance Pattern of Salmonella Species Recovered from Livestock and Poultry

“…Another study from India also recorded moderate resistance in Salmonella Newport isolated from poultry and animal origin foods. However, a high degree of sensitivity was observed against ciprofloxacin, chloramphenicol and cefuroxime (Kumar et al, 2016). Isolates of our study were mostly sensitive to cephalosporins but they have shown resistance to colistin, tetracycline and certain penicillin group of antimicrobials.…”
