Summary: This study investigated the self-decay laws and efficiencies of airborne bacteria in different temperatures and found that gram-negative and gram-positive bacteria had similar self-decay efficiencies, but gram-negative bacteria were more sensitive to temperature changes. The study also revealed that biological-decay and physical-decay followed a first-order kinetic model, with biological-decay being the dominant process influenced by energy absorption, environmental stress, and bacterial structure changes. Overall, this study is significant for understanding the changing laws of bioaerosols and controlling the transmission of airborne bacteria.

Summary: This study developed and tested a stationary electrostatic bioaerosol collector with a high concentration rate while preserving viable and culturable microorganisms. The collector showed comparable physical collection efficiency to the filter sampler, with increased viability and culturability efficiency. The elution liquid volume and hydrophobic coating method were optimized to achieve a sample concentration rate of 5 x 10⁴ min⁻¹, enabling faster detection of bioaerosols.

Summary: This study demonstrates a method for direct capture of airborne droplets on a paper microfluidic chip without the need for additional equipment. By adding antibody-conjugated submicron particle suspension and using a smartphone-based fluorescence microscope, the capture-to-assay time was less than 30 minutes. This approach allows for the direct detection of SARS-CoV-2 in a handheld and low-cost manner, contributing to slowing its spread.

Summary: Devices for the filtration and sterilization of indoor spaces have been widely used due to the COVID-19 outbreak. This study aimed to identify important factors for evaluating air purifier efficiency in large chambers. The distribution characteristics and natural reduction of airborne viruses were investigated, and it was found that the airborne-virus removal efficiency should be evaluated after 40 minutes for accuracy. Additionally, the sampling efficiencies of different samplers were compared, with the impactor showing the highest efficiency and lowest standard deviation.

Summary: The study focuses on developing a sampling and analytical method for virus-laden bioaerosol, and reports recovery test results for SARS-CoV-2 concentration step through ultracentrifugation. A surrogate beta-coronavirus, human coronavirus strain OC43, was used to validate the recovery tests. It was found that the elution efficiency of coronavirus OC43 from filters could be enhanced by using an elution buffer containing fetal calf serum.

Summary: This study used qPCR and high-throughput sequencing to analyze the microbial dynamics of ambient PM2.5 filters under constant conditions. It found that polluted PM2.5 had faster decay rates, higher bacterial diversity and lower fungal community compared to non-polluted PM2.5, with saprotroph fungi making up a large portion of the population. The research also revealed stable community structures and different metabolic survival strategies of airborne microorganisms in ideal and stable conditions.

Summary: This study investigates the characteristics and compatibility of a human H1N1 virus with avian H9N2 derived genes. The study finds that the avian PB1 gene of H9N2 increases the polymerase activity of the RNP complex in H1N1. The higher polymerase activity suggests that the avian PB1 gene may drive the evolution and adaptation of reassortant viruses in humans. This study provides important insights for pandemic preparedness.

Summary: The H9N2 subtype avian influenza virus (AIV) has become endemic in poultry globally, but it is not effectively monitored and controlled due to its low pathogenicity. The recent reports of human infection caused by H9N2 AIV have raised public concerns. This study investigated the genetic and antigenic characteristics of H9N2 AIV isolated from local markets in Southern China, providing new insights on the antigenic diversification of H9N2 viruses.

Summary: The purpose of this study was to investigate the effects of increasing ambient temperature on heat loss from the skin surface and respiratory system of dairy cows at different relative humidity and air velocity levels. The results showed that skin heat loss decreased with increasing ambient temperature, while skin latent heat loss increased. Relative humidity and air velocity had no significant effect on heat loss. Under long exposure conditions, cows lost more heat compared to short exposure conditions.

Summary: Foot-and-mouth disease (FMD) is a significant hindrance to livestock production in Thailand. This study conducted a temporal and spatial analysis of FMD outbreak reports from 2011 to 2018 at the subdistrict level. Risk factors associated with FMD outbreaks were also investigated. The study identified high-risk areas and periods of FMD outbreaks in Thailand, providing valuable information for optimizing FMD control programs in Thailand and other countries with similar livestock industries and FMD situations.

Summary: The effects of ambient temperature, relative humidity, and air velocity on total evaporative water loss from dairy cows were studied. The results showed that relative humidity and air velocity had no significant effect, while their interaction with ambient temperature was significant. Cows at high relative humidity had a lower increasing rate of evaporative water loss compared to cows at low relative humidity. Cows at medium and high air velocity levels had a greater increasing rate. This study implies that cows mainly rely on evaporative cooling from the skin in high temperature conditions.

Summary: This study systematically studied the 2001 foot-and-mouth disease epidemic in Uruguay and found that in the high-risk period, factors such as animal movements, farming methods, farm size, and geographical location were associated with the probability of infection. In addition, dairy farms had a higher probability of infection during the early stages of the epidemic. The delay in detecting the index case increased the likelihood of this large-scale epidemic.

Summary: In environmental transmission, correctly modeling the mechanisms of pathogen shedding, decay, and transmission dynamics is crucial for accurate predictions and evaluations of interventions. We present a stochastic environmental transmission model with a new scaling method for shedding rate parameter and a new estimation method that distinguishes transmission rate and decay rate parameters. Our exposure-based estimation method correctly estimates the transmission rate and decay rate parameters, while the commonly used trajectory-based method fails. Correct estimation of these parameters is important for extrapolating environmental transmission models and predicting intervention effects.
