Summary
From the paper "Non-Mammalian Multi-Cellular Model" it is clear that Drosophila has a short time for generation yet has an inborn system of immunity similar to that of humans. The model is therefore vital in the study of such pathogens as L.pneumophila and Staphylococcus aureus…

Extract of sample "Non-Mammalian Multi-Cellular Model"

Key among the disadvantages of the model arises from its inability to survive at temperatures below 27°C. Among the pathogens tested through this model, include Mycobacterium Tuberculosis, Pseudomonas aeruginosa and Salmonella typhimurium.   

Drosophila

Commonly known as the fruit fly, Drosophila melanogaster is a perfect organism that spends its life cycle as a decomposing organic matter. Drosophila’s unique characteristic instinctive resistant response against pathogens makes it a perfect model for study (HILL, OLSON & GRIENDLING, 2012). Another feature that makes the multi-cellular model in biological studies is its ability to toll-like receptors. Zebrafish has unique characteristics that make it an appropriate model in the study of pathogens. Key among such features is a developed immune system. This makes it ideal for studying the manifestation and the interactions of pathogens with either adaptive or innate immune systems (BUBANOVIC, 2004). The advantages of using zebrafish in studies arise from their ability to reproduce rapidly thus high population and ideal size. The model is essential in the study of such pathogens as Staphylococcus aureus, Salmonella enterica and Mycobacterium marinum.
