An attempt is made to a novel narrow-spectrum β-lactamase CTX-M-215 identified in an Escherichia coli clinical isolate in China and conferring high-level resistance to mecillinam but not to cefotaxime. CTX-M-215 differed from CTX-M-125, a CTX-M extended-spectrum β-lactamase (ESBL), by an N132D substitution, which decreased hydrolytic activities toward penicillins and cephalosporins except for mecillinam. High similarity was observed between CTX-M-215- and CTX-M-125-bearing plasmids, carried by different isolates in the same patient, indicating in vivo evolution of CTX-M-215 from CTX-M-125. This plays a vital role in providing the best possible care in the best possible manner. Therefore, these antigens were known to have given a very positive effect on the overall recovery and have hastened the same by an average of 58 percent. This has been able to leave a very important impact over the same in the best possible manner, It was discovered that in the population of 4800 people, wherein 99 percent were already suffering from the deadly disease of cancer, the effect of antigens is very much appreciated. The antigens like anti-laminin if injected into the nerves of the patients in the ratio of 8.10 mg/l would be helpful in the long run as they not only help in protecting the people from any form of side effects but also will control the abnormal growth rate of the cells by 2000 per day.
