Background: Methicillin-resistant Staphylococcus aureus (MRSA) is often the cause of serious ocular infections that are difficult to treat, and these ocular infections are a significant public health problem.
Aims and Objective: The study aimed to determine the prevalence and antimicrobial susceptibility pattern of MRSA in ocular infections.
Materials and Methods: The patients were recruited from the outpatient and inpatient departments from July 2018 to February 2021 from the Institute of Ophthalmology and study was done in the Department of Microbiology, JNMC, AMU, Aligarh (UP). MRSA was identified by Cefoxitin disk diffusionmethod. Polymerase chain reaction was used for detection of mecA gene.
Results: Seventy-six S. aureus were found in 350 patients with clinically suspected various bacterial infections. Among all S. aureus, 41 (53.94%) were MRSA. Maximum 10 (24.4%) MRSA were isolated from lacrimal apparatus infection followed by 7 (17%) in lid infection, and 6 (14.6%) in keratitis. All MRSA isolates were positive for mec A gene. MRSA isolates showed 85.3% sensitivity to amikacin and 100% to vancomycin. Fluoroquinolones showed resistance to the majority of MRSA strains.
Conclusion: MRSA is the main pathogen of ocular infections, resistant to a wide range of antibiotics. The monitoring of antibiotic sensitivity patterns, regular surveillance of associated ocular diseases, and strict antibiotics policy should be followed in an institute.
Emerging viruses causing Acute Encephalitis Syndrome (AES) can be more damaging due to irreversible brain damage, irrespective of the identical medical characteristics created by all agents. We report two cases of acute encephalitis syndrome caused by Japanese encephalitis virus from a usually under-reported geographic region of India. Both patients were managed conservatively with favourable outcome in one of them.There should be considerable effort to identify the particular causative agent that triggers AES, bearing in mind the various clinical manifestations of Japanese encephalitis virus. Although there is no significant impact on management, it is possible to prevent transmission to healthy contacts and the community through vector control and vaccination.
Plasmodium knowlesi is a parasite that can spread from animals to humans. Over the past 20 years, scientists have become more and more interested in this parasite. This parasitic zoonotic infection is common in Southeast Asia, and 6-9 % of symptomatic adult who get it have severe symptoms. In this review paper, we will discuss recent and past studies on P. knowlesi. Additionally, we will describe the epidemiology, clinical aspects, diagnosis, and therapy of this infectious disease. In addition to this, we concentrate on the difficulties associated with the prevention and management of this important parasitic zoonotic disease.
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.
