Cultivation of fungi

Molds are the major fungal organisms that can be seen by the naked eye. These can be commonly seen growing on foods such as bread or citrus fruits. These grow as cottony fuzzy, black, green, or orange-colored depending on the type of molds. These are composed of intertwining branches called mycelium. The filaments that make up the mycelium are called hyphae. Most of the branching mat grows on and in the surface of the nutrient medium so that it can extract nutrients. Therefore, the mat is also called vegetative mycelium. Some of the mycelium grows upward from the mat, termed as aerial mycelium. Some of the aerial mycelia are specialized, these give rise to spores (reproductive elements). For the cultivation of molds, specialized media are used such as Sabouraud agar or potato dextrose agar. These media favors the growth of molds due to their low pH (4.5-5.5) and ultimately discourage the growth of bacteria. These are slow-growing and requires several days for their growth

Sugar •        Sugar has been described both in history and recently as a topical wound treatment. •        The basis for its use is its high osmolality. •        Thus, it is effective in reducing edema due to its hydrophilic action. •        It has also been reported to attract macrophages, accelerate slough of devitalized tissue, provide cellular energy, and promote granulation tissue. •        Its use should be discontinued after the wound has a good bed of granulation tissue. •        It has been reported to be effective against Staph., Strep., Enterobacter, E. coli, Klebsiella, Pseudomonas, and Serratia organisms. •          It reportedly does not cause hyperglycemia. •        It should be used with caution on large wounds. Its hydrophilic action can pull more fluids, electrolytes, and proteins from the wound tissues.

Nematodes

Image
    General Characteristics: Nematodes are commonly called roundworms because, as the name suggests, they are round when viewed in cross section. They are cylindrical in structure and taper towards their anterior and posterior ends. They are bilaterally symmetrical. The sexes are separate in most species, a few are hermaphrodite. Nematodes that parasitize domestic animals are found in all parts of the body but are most commonly found in the digestive and respiratory tracts, and in the circulatory system.
