Background Info:
Mold is a group of fungus that are a decomposer in nature. They are basically a single celled organism with thousands of nuclei. They nearly have the same life cycle as fungi. They are made up of filaments, called hyphae.They can be found in shady, damp areas outdoors, like rotting logs, or any place with decomposing vegetation. There are also parasitic molds, that live off a host. . Mold can reproduce with itself, asexually, and with other molds, which would be sexual reproduction. They use single celled bodies, called spores, to do this. Mold can have aerial spores, or even spores in the water, from water molds. Bacteria can communicate with each other. Spores are extremely versatile, and can even go dormant, for up to 75 years, and then still germinate. The have receptors that can detect positive or negative chemicals. They can sense the environment, and make decisions. I think mold will be able to have the same social interactions, and be able to know where, and where not to go. A well studied mold is the slime mold, or Physarum polycephalum. This mold, like many other inhabits shady, moist areas, such as under decaying logs. It is usually yellow in color, and eats bacteria, fungal spores, and other microbes. To consume its food, it surrounds it, and uses enzymes to break it down. Since it consumes food like this, it is not harmful. As food starts to run out, it goes into its reproductive state. Physarum polycephalum can anticipate changes. Even though they do not have a brain, or central nervous system. It can anticipate change, when dealing with its environment. I always wonder if organisms like this can think at all. Also, if we were once like this mold, as we did start as small organisms. As we e...

Polyphemus is a semi-human, man-eating monster with a single eye in the center of his forehead. He was referred to as a cyclops. He is the son of Poseidon and Thoosa, and lives on an island devoted to cyclops. Polyphemus means abounding in songs and legends.
The Meningeal Worm Infestation of up to 20 meningeal worms has been discovered in a single deer’s subdural cavity. The white tail deer are the preferred host, but they rarely ever suffer from any sick or neurological problems from this type of worm. We will see severe signs in llamas and alpacas; these are the two animals that can become infected with it frequently. The meningeal worm can cause damage to the central nervous system and could result in death, so it is important to try and catch it early and learn about how to prevent this deadly worm. Things that you should be familiar with about the meningeal worm are its life cycle, the signs in your animal, and any prevention or treatment options.
Sabellaria cementarium belongs to the phylum Annelids and is an invertebrate polychaete species. They are found in small clumps at the rocky bottoms of the sea floor where they use the rich source of natural phytoplankton as their primary diet (Qian and Chia, 1990). The tube-like worms can behave social and form extensive reefs or independently build hollow tubes in to the sandstone (pawlik and Chia, 1991). Embryos form a polar lobe that is absorbed in to the blastomeres at the end of division. Larval development and movement follows shortly after the 14-15 hour fertilization period where spiral cleaving of the fertilized oocytes appears (Render, 1983). Much is still not known about the invertebrate worm in their natural niche.
Naegleria fowleri is a single-celled, protozoan pathogen found in fresh bodies of water and soil around the world (Skurie; Byrd 8). It thrives in the layer of sediment at the bottom of lakes and ponds. (Skurie). When living in soil, the N. fowleri, along with other protozoa microbes, clings to plant roots searching for bacteria (Byrd 261). This pathogen is a free-living pathogen classified as an amphizoic amoeba therefore it survives in a free state throughout soil and fresh water while having the ability to be a pathogen (Marciano-Cabral, “Immune”). It primarily seeks bacteria due to an inability to create food (Byrd 27); however, N. fowleri will attack a host if given the opportunity. In addition, it has been proven pathogens of the brain are often able to control the actions of their host to better suit the pathogen’s needs. An example may be to cause the host to have a high body temperature, wanting to stay warmer, or sleeping more often (Byrd 225). This microbe is typically found in the form of trophozoite, cyst, o...
Amoebae of the genus Naegleria are identified in part by their ability to create a temporary flagellate phase once exposed to nutritional scarcity. N fowleri is confirmed to be a typical eukaryotic protist by electron microscopy examination (Patterson et al., 1981).

Mold is, in fact, a fascinating organism which has had many different uses over the years and our lives would not be the same without it.
Microorganism is a living thing that cannot be seen by naked eye and is so small in size. Microorganism usually can be seen through microscope because microscope have the ability to see small thing using various magnification. The examples of microorganism are bacteria, fungi, protozoa, algae and virus. Among all of the microorganisms, bacteria have the greatest advantages in preserving food and beverages. Bacteria are generally harmless but can produce enzymes that can alter the structure the food. In extreme cases, bacteria can secrete toxic substances that can cause the food to spoil.

In this essay, I will be explaining the unexpected signs of life that Leeuwenhoek found in a single droplet of rainwater which he described as ‘little animals’. He had witnessed bacteria and protozoa, laying the foundations for the sciences of bacteriology and protozoology. Leeuwenhoek also found ‘little animals’ in other bodies of water, including lakes, and on the surface of pepper and teeth. Additionally, with regards to the essay, I will also begin to identify the new and useful information established in Leeuwen...
C. immitis is non-fastidious growing on a variety of culture media including brain-heart infusion agar, potato-dextrose agar, Sabourand-dextrose agar and blood agar. (3) Culture to induce mycelial growth is best at 28-30oC typically taking 2-3 weeks with growth detectable within 5 days. (3, 6, 7) The colony is initially white and glabrous, quickly becoming floccose resembling angel hair (see picture 1) and turning brown as it ages. (3, 6) Microscopically the culture shows single celled barrel-shaped alternate arthroconidia (see picture 2) separated from each other by a disjunctor cell.(6, 8) Conversion to the yeast / spherule form re...
Mold is a member of the fungi family. Since mold is part of the fungi family, it cannot use the sun to obtain energy. This means that mold has to use other plants or animals to grow. Even though they cannot see them, there are millions of mold spores in the air. These spores settle down and start to multiply which can be done rapidly or slowly as long as it has a food source. Mold usually grows best in warm environments, but it can still grow in cold environments also. Mold can cause illness such as vomiting or feeling nauseated when it is eaten or when it smells bad.
A biofilm is a layer consisting of various combinations of many different organisms, autotrophic and heterotrophic. They are dense, organized communities of cells, encased in a self-produced slime. The bacteria grow together in water like atmospheres, attaching to a solid surface, forming a small ecosystem. Biofilms are known as micro-environments, micro-habitats, or slime matrix. They help decompose dead organisms and recycle carbon and nutrients.
The reproductive system was mainly located towards the anal area and inferior to the stomach. The penis was located in the middle. It was white in color and looked like a mealworm. The seminal vesicles were located on both sides of the penis. They were grayish pink in color and looked like walnuts.
