BACKGROUND Monitoring emerging trends in antimicrobial resistance at local levels is a very important aspect for clinical decision making and infection control interventions in this era of rising superbugs. The hospital antibiogram constructed by standardized methods is a summary of antimicrobial susceptibilities of local bacterial isolates, with periodic review. METHODS This antibiogram was prepared based on the Clinical and Laboratory Standards Institute (CLSI) M39-A4 guidelines. The data was collected for a period of three years from May 2016 to April 2019. All the samples which were received in the microbiology laboratory for aerobic bacterial culture and sensitivity testing were considered. Antibiotic susceptibility data of the bacterial isolates processed by VITEK2 system was considered. A hospital antibiotic policy was formulated and implemented. RESULTS A total of 15,135 samples were analysed from different clinical departments for a period of three years, of which 5,638 were culture positive. A comparative analysis of the three years' data during the introduction of antibiotic protocol showed a gradual decrease in the rate of infection with multidrug resistant organisms. The prevalence of Methicillin Resistant Staphylococcus aureus (MRSA) showed a decrease from 15% to 7%. Extended spectrum beta-lactamase (ESBL) producing Escherichia coli in urine decreased from 42.4% to 27%. CONCLUSIONS Prompt antimicrobial therapy in case of an infection makes a lot of difference between recovery and death and most of the time prevents long term disability. Hence, antibiotic policy is one of the mandatory requirements, and making an antibiogram is the first step before framing antibiotic policy.
Gram negative sepsis and intestinal opportunistic infections including Cryptosporidium, Isospora, Cyclospora, Microsporidia, S.stercoralis and Candida albicans are increasingly becoming prevalent in acquired immunodeficiency syndrome (AIDS) patients. These infections are clinically important primarily because many of these have the potential for serious and even lethal complications in immunosuppressed patients. Here, we are reporting a patient with Gram-negative sepsis, who was found to be co-infected with three of these opportunistic pathogens. She was also found to be positive for human immunodeficiency virus (HIV) antibodies. To our knowledge, this has been reported once previously, and serves as a reminder to actively exclude S.stercoralis infection in immunocompromised individuals presenting with bacteraemia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
