To investigate the subtype of CTX-M-type extended-spectrum β-lactamase encoding gene and to research the resistance of Klebsiella pneumonia in Jilin Urban Area, and analysis the epidemiological aspect of CTX-M-producing isolates. PCR was used to detect CTX-M encoding gene in 118 strains of Klebsiella pneumoniae. Disc diffusion method was used to determine 14 kinds of antibiotics resistance for positive...
Summary form only given. Dermatophytes are the most common aetiological agents, which invade into keratinized tissues (skin, hair, nails) of humans and animals causing dermatophytosis (also known as ringworm or tinea). Swimming pools, fitness centers, barber shops, beauty parlors, saunas and steam baths are common places to pick up superficial fungal infections. Mycotic infections have become more...
Summary form only given. Formocresol and calcium hydroxide are commonly used as the clinical disinfectant of root canals. Although they have strong chemical disinfection properties, their cytotoxic effects have always been a concern. E. faecalis, which is responsible for root canal failure, can also cause life-threatening infections in humans, especially in the nosocomial (hospital) environment, where...
Summary form only given. Aqueous environments are susceptible to contamination by bacteria, protozoa and viruses, which are the root cause of various illnesses. These contaminations are usually treated by chemical methods. Recently, attempts have been made to inactivate bacteria in water with non-thermal plasmas using various approaches, e.g., a pulsed streamer discharge plasma or a gliding arc discharge...
Technology of bioaugmentation was used to degrade contaminants of river water. It was realized that degradation effectives was affected by the density of added microbes. Improving the density of microbes was necessary to reach satisfactory degradation effects on the contaminated river. Therefore a practical recycle cultivation method was studied. It was proved to be practical and effective, for easy...
A direct-current cold atmospheric-pressure air plasma microjet (PMJ) based on the microhollow cathode discharge design is used to inactivate six types of bacteria within a small well-defined area on a large Petri dish. We show that the PMJ is very effective in inactivating bacteria in their vegetative state as well as in the spore state within the area of plasma exposure. We also observed that bacteria...
