Haemophilus bacilli are extremely small species of pathogenic bacteria. For their survival and growth, this species require biological molecules like heme present in blood and also NAD +. Due to this, they are found to be parasitic in animals and humans. The most common example of Haemophilus pathogens is Haemophilus influenzae, which causes a number of respiratory related diseases like flu, sinusitis, bronchitis, and pneumonia. The bacteria in this genus can change their shape in many forms, and they have the presence of a polysaccharide capsule, which prevents them from phagocytosis. The presence of different types of capsule also helps the scientists to distinguish between different strains of this genus. Type B strain, identified by its capsule, causes most of the H. influenzae diseases, including some fatal diseases in children like arthritis and meningitis.

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
