E.coli Types
According to the different biological characteristics, pathogenic e. coli can be divided into 6 groups.
Enteron pathogenic escherichia coli (EPEC),
Enteron toxigenicity escherichia coli (ETEC),
Enteron invasive escherichia coli (EIEC),
Enterohemorrhagic e. coli (EHEC),
Enteron adhesion of e. coli (EAEC),
Diffuse adhesion of e. coli (DAEC.).
E. coli belongs to gram-negative bacteria (G -).

Easy Treatment of Diesel Leakage
During the use of diesel engines, oil leakage sometimes occurs. Its simple processing method is: Injector nozzle return oil nozzle is a precision component. If the diesel engine uses unclean diesel or the machine is used for a long time, it will return due to the wear of the nozzle. However, replacing the fuel injectors is costly and uneconomical. To prevent the oil from leaking, the oil can be led back to the tank via a return pipe or a diesel filter can be introduced. If the return pipe is damaged, a plastic pipe can be used to introduce the oil into the self-contained container, filtered and then returned to the tank. The oil leakage in the oil delivery part can be properly handled separately: the gasket of the hollow screw of the oil delivery pipe is not flat, the gasket can be removed, and the gasket can be removed. If it still can not solve the problem, replace the new gasket, or use a thicker soft plastic material to cut. Replaced by washers; oil leaks from plastic hoses and metal fittings are mostly caused by hardening or cracking of plastic hoses. They can be cut hardened and broken, then hot water can be used to soften them, and they can be hot-mounted on metal fittings. Bundle; metal pipeline rupture oil leakage, can be welded with a brazing site. In addition, in order to prevent the oil pipeline from cracking, when installing the pipeline, the camber should be appropriate. Do not pull it tightly to install it. The pipe body should not be in contact with the fuselage to avoid wear. When the valve cover leakage valve cover is installed, if the fastening force is too large, it is easy to deform and leak oil. At this time, the valve cover of the oil spill can be removed, and carefully trimmed with a wooden stick to restore the contact surface to a flat surface. Then, the gasket can be placed and installed.
