Pulmonary Model

With the aging of the population and the aggravation of environmental pollutants (including tobacco smoke), the health effects on human lung tissues are becoming more and more serious. Airway diseases such as chronic lung inflammation (including chronic obstructive pulmonary disease and asthma) are harmful Human health is causing more and more damage. The causes of these problems are induced by pro-inflammatory molecules that respond to acute infections, but they usually lead to chronic immune responses that induce acute crises and damage of lung tissue over time.

The lung inflammation is usually caused by inhaled pathogens. Pneumonia is a common disease clinically and is usually easier to treat, but in some individuals with compromised immune systems, more severe symptoms usually occur. Although current therapies are generally able to combat deadly diseases, the emergence of antimicrobial-resistant strains of bacteria requires further research to identify novel therapies. Creative Diagnostics has established a lung research platform that can screen candidates with antimicrobial activity for infections in the body to quickly determine the most promising clinical therapies.


We have established lung infection models in mice and rats, in which animals are infected with pathogens by intranasal (IN) or intratracheal (IT) instillation. After the infection is complete, it can be through nebulization, oral tube feeding (PO), intranasal (IN) or intratracheal (IT) drip or intravenous (IV), intraperitoneal (IP), intramuscular (IM) or subcutaneous (SC) Animal testing of candidate antibacterial drugs by injection. In this process, we can provide customized services for each research parameter (animal strain, pathogen, comparator and dosing schedule) to meet customer needs.
