Abstract Outbreaks of serious mortality among cultured juvenile cobia Rachycentron canadum L . (weighing 8–10 g) characterized by lethargy, dark skin and ascites in the peritoneal cavity while some fish possessing damaged eyes occurred July August 2001 Taiwan. Fifteen motile bacterial strains were isolated from head kidney and/or on tryptic soy agar supplemented with 1% NaCl (TSA1) thiosulphate citrate bile salt (TCBS) sucrose plates during two outbreaks. All isolates identified as Vibrio...

Asian residential communities are usually dotted with various spot pollution sources (SPS), such as restaurants, temples, and home factories, traffic arteries passing through, resulting in higher intra-urban variability compared their western counterparts. Thus, it is important to characterize spatial of pollutant levels order assess accurately residents' exposures communities. The objectives this study the actual within an urban area evaluate influence vehicle emission SPS on exposure...

Airborne Staphylococcus aureus causes a significant proportion of nosocomial infections. The purpose this study was to combine real-time quantitative polymerase chain reaction with the DNA-binding agent propidium monoazide (PMA-qPCR) assess exposures airborne S. aureus. In work, we generated aerosol and used our assay detect viable, in chamber. biological collection efficiencies three samplers (the AGI-30 impinger, BioSampler, Nuclepore filter sampler) were evaluated using aerosols. effects...

Vancomycin-sensitive and vancomycin-resistant Enterococcus (VSE VRE) species have become a significant health problem. CHROMagar medium, which permits direct, color-based identification of target pathogens, could potentially be used to rapidly monitor airborne VSE VRE. In this study, the efficiency VRE medium without vancomycin supplementation (CVSE) for collecting vancomycin-sensitive faecalis was evaluated in chamber study. Subsequently, performance bioaerosol samplers combined with CVSE...

In recent decades, the rise of methicillin-sensitive Staphylococcus aureus (MSSA) and methicillin-resistant S. (MRSA) has become one most significant problems in public health. The CHROMagar medium, which allows for direct color-based identification target pathogens, could potentially be used to rapidly monitor airborne MRSA. this study, recovery efficiency Staph (CSA) collecting MSSA was evaluated a chamber study. Subsequently, colony performance bioaerosol samplers combined with CSA MRSA...

Acinetobacter baumannii represents a significant cause of nosocomial infections. Therefore, we combined real-time quantitative polymerase chain reaction (PCR) with the propidium monoazide (PMA-qPCR) to assess feasibility detecting viable, airborne A. baumannii. The biological collection efficiencies three samplers for collecting were evaluated by PMA-qPCR in chamber study. After sampling, effects storage fluid on evaluated. results showed that culturable ratio measured using culture method...

O-29A5-3 Background/Aims: 1,4-Dichlorobenzene (1,4-DCB) has been widely used as toilet deodorizer, repellent, and mothballs. Because of its high volatility, human may expose to 1,4-DCB through inhalation, eye/upper respiratory tract irritation abnormal liver/kidney functions have reported in occupational exposure. It is desired find suitable biomarkers exposure health effects for the workers repellent product plants. In this study, we established a novel method measure metabolites 1,4-DCB,...

Background: Characterization of spatial variability pollutant levels is important to actually assess the residents' exposure in their communities. Especially Asian countries, mixed commercial and industrial activities, such as restaurants, temples, home factories, exist within residential Moreover, housings are built along roadways with heavy traffic front them. This phenomenon results higher intra-community pollution than those western countries. Aim: The objective this study contribution...
