“…The spread of multidrug resistant Staphylococci in environment from different sources has already been reported in India [ 30 , 35 – 37 ]. Furthermore, Staphylococci species such as MRSA and MR-CNSs are the biggest contributors in the spread of antibiotic resistant genes (ARGs) in the environment as reported from India and as well as from abroad [ 3 – 5 , 9 , 38 ]. CNSs are the common microflora of human skin, however, they can be pathogenic and virulent if they colonizes the open wounds.…”

“…Apart from frequently associated with nosocomial infections, these infectious agents are also of great concern in a variety of indoor environments such as libraries, offices and other residential indoors [ 10 , 34 ]. Although, we have adequate knowledge of MRSA epidemiology and its role in spreading antimicrobial resistance (AMR) in the environment, there is comparatively scant knowledge of MR-CNS epidemiology in indoor bioaerosols and its AMR pattern in India, which is imperative to evaluate the indoor air quality [ 9 , 11 , 21 , 22 , 41 ]. Lately, multi-drug resistant CNSs have been dominating in all kinds of microbiomes whether it is environmental samples, hospital-wastes, poultry, agricultural farms etc., thereby they are equally clinically relevant [ 15 , 36 , 42 ].…”

“…Therefore, checking the bacterial burden in indoor air has been frequently practiced in the hospital settings in order to mitigate the hospital-associated infections (HAIs) [3,5,6]. However, with the prevailing airborne antimicrobial resistance (AMR) and ARG in different environmental settings [4,8,9], the quantification of airborne indoor microbiome is a need of the present moment. Among airborne culturable bacteria, Staphylococcus species are the most common both in residential [10] as well as in hospital indoors bioaerosols [6,11].…”

Humanity has been facing the threat of a variety of infectious diseases. Airborne microorganisms can cause airborne infectious diseases, which spread rapidly and extensively, causing huge losses to human society on a global scale. In recent years, the detection technology for airborne microorganisms has developed rapidly; it can be roughly divided into biochemical, immune, and molecular technologies. However, these technologies still have some shortcomings; they are time-consuming and have low sensitivity and poor stability. Most of them need to be used in the ideal environment of a laboratory, which limits their applications. A biosensor is a device that converts biological signals into detectable signals. As an interdisciplinary field, biosensors have successfully introduced a variety of technologies for bio-detection. Given their fast analysis speed, high sensitivity, good portability, strong specificity, and low cost, biosensors have been widely used in environmental monitoring, medical research, food and agricultural safety, military medicine and other fields. In recent years, the performance of biosensors has greatly improved, becoming a promising technology for airborne microorganism detection. This review introduces the detection principle of biosensors from the three aspects of component identification, energy conversion principle, and signal amplification. It also summarizes its research and application in airborne microorganism detection. The new progress and future development trend of the biosensor detection of airborne microorganisms are analyzed.

Airborne bacterial community associated with fine particulate matter (PM2.5) under different air quality indices in Temuco city, southern Chile

Temuco (Chile) is one of the most polluted cities in Chile and Latin America. Although the fine fraction of particulate matter (PM 2.5 ) has been extensively studied and monitored due to its negative impact on public health, its microbiological components remain unknown. We explored, the airborne bacterial community in PM 2.5 under good, moderate, alert, pre-emergency and emergency indices of air quality (AQIs) established by the Chilean government. Bacterial community relationship with environmental factors (PM 2.5 , PM 10 , carbon monoxide, among others), was also evaluated. Significant differences in PM 2.5 bacterial community composition associated with AQIs were revealed, using 16S rRNA target sequences of denaturing gradient gel electrophoresis (DGGE) bands. Bacterial communities in PM 2.5 were mainly clustered (80%) into emergency and pre-emergency samples. The dominant phylum was Proteobacteria and most abundant genus was Novosphingobium, traditionally related to opportunistic respiratory diseases. The main factors associated with community structure were PM 2.5 , PM 10 and carbon monoxide concentrations. This study exposed that bacterial community composition in Temuco varies according to AQIs, with the occurrence of potential opportunistic bacteria on heavily polluted days.
