Objective:
Resistance of Staphylococcus aureus (S. aureus) against common antibiotics has been increasing given the rampant use of antibiotics. Methicillin-resistant S. aureus (MRSA) is particularly important because it has been reported to present in hospital-acquired as well as community-acquired infections. Our aim was to study the types and subtypes of MRSA isolated from nasal swabs taken from volunteering dental school students and to assess and analyse the knowledge of dental health care workers (DHCWs) on MRSA and prevention of its infection.
Methods:
A total of 100 participants, which included staff, students, and dental auxiliaries, from the School of Dental Sciences, Krishna Institute of Medical Sciences, Deemed to Be University, Karad, India, were included in the study which was conducted from June 2020 to 1 June 2021. All the participants completed a survey and underwent collection of nasal swabs. The samples were cultured and underwent microbiological and molecular analysis for MRSA. The questionnaire was sent out electronically via SurveyMonkey.
Results:
Sixty-three percent of the participants were female. The majority were undergraduate students (66%) and younger than 25 years (77%). The prevalence of MRSA in the sample was the MRSA type SCCmec type V (54.8%). The survey reports a lack of knowledge amongst dental students on MRSA and prevention of its infection. The majority (69%) of participants had not heard of MRSA infection and had inadequate knowledge of MRSA infection. Only 29% of the participants think that a healthy person may have MRSA without feeling ill. Eighty-five percent of the participants reported that they have written polices and guidelines to control MRSA. Eighty-five percent of the participants indicated that they are less confident in their knowledge on MRSA infection control protocols, and 94% mentioned that the dental clinics have written guidelines for hand hygiene.
Conclusions:
DHCWs have limited knowledge of MRSA infection, emphasising the need for appropriate clinical training. Academic institutions should promote effective infection control training to protect students, faculty, and other employees.
Insights
Dental healthcare workers show limited knowledge of Methicillin-resistant Staphylococcus aureus (MRSA) infection and its prevention, despite its prevalence. Enhanced training is crucial for infection control in dental settings.
Area of Science:
- Microbiology
- Infectious Diseases
- Public Health
Background:
- Antibiotic resistance is a growing global health concern.
- Methicillin-resistant Staphylococcus aureus (MRSA) poses a significant threat in both hospital and community settings.
Purpose of the Study:
- To identify MRSA types and subtypes in dental students.
- To evaluate the knowledge of dental healthcare workers (DHCWs) regarding MRSA and infection prevention.
Main Methods:
- Nasal swabs collected from 100 dental school participants (students, staff, auxiliaries).
- Microbiological and molecular analysis for MRSA identification.
- Survey administered to assess DHCW knowledge on MRSA and infection control.
Main Results:
- SCCmec type V was the predominant MRSA subtype (54.8%).
- A significant lack of knowledge regarding MRSA infection and prevention was reported among participants.
- Many DHCWs expressed low confidence in MRSA infection control protocols despite existing guidelines.
Conclusions:
- Limited DHCW knowledge necessitates targeted clinical training on MRSA.
- Academic institutions must prioritize comprehensive infection control education for all dental personnel.

Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
