A number of toxins, created by molds on food can cause severe illness. Produce, cheese and breads are the most common foods where molds are created. One easy way to prevent getting contaminated by infected food is not to taste foods that smell or look irregular. Another easy way to prevent contamination is to stick with the recommended dates on the food labels. Our classmate Ron mentioned E.Coli and Salmonella, these two are food borne bacterias with salmonella being the most common cause of…

bacterial disease infecting the larynx, pharynx, nose and tonsils. It is an upper respiratory tract illness characterized by sore throat, low grade gever and adherent membrane. The name of the disease come of the Greek Diphtheria. it means leather hide. The bacterium responsible is Corynebacterium diphtheriae. C. diphtheriae is an aerobic gram-positive toxin-producing bacillus. It is highly contagious upper respiratory tract infection. The onset symptoms are sore throat, low-grade fever, and…

Usually M.Luteus is found in environments where the temperature is around 37 °C [3]. Also, M. Luteus is aerobic microorganism which favor oxygen environment which can be easily found on the mucosal linings of the upper pharynx, human mouth, and respiratory tract. M. Luteus can grow well in environments with little water or high salt concentrations. On human skin, M.Luteus breaks down compounds in sweat into compounds with bad odor. Also, it can be easily grown on Simmon 's citrate agar or on…

Smooth muscle in the digestive tissue perform peristalsis which moves food through the digestive tract. The muscular system is reliant on the constant nutrients that the digestive system provides. Glucose is absorbed from the digestive system and delivered into the mitochondria of muscle cells. The mitochondria uses the glucose to create ATP. 4. Nervous…

Abstract The crucian carp is an actinopterygii fish which is known to possess a swim bladder and non-muscular lobed fins. These fishes are also known as ray finned fishes. The fish contains the organs responsible for the digestion, respiratory, circulatory and nervous system. In order to observe the internal organs of the fish, the fish firstly is euthanasiated with clove oil. The external anatomy of the fish has five fins; pectoral, pelvic, dorsal, anal and caudal fin, a cloaca is located…

axons within the white matter have small structural units called tracts and bundles of tracts are fasciculi. The tracts serves to conduct either sensory nerve signals (ascending tracts from the spinal cord to the brain) or the motor nerve signals (descending tracts from the brain to the spinal cord). The anterior and lateral funiculus have both ascending and descending tracts. Whereas the posterior funiculi contain only ascending tracts. The sensory pathways use a series of two or three neurons…

disease. Streptococcus pyogenes is in the phylum Firmicutes, the class Bacilli, the order Lactobacillales and the family Streptococcaeceae (Brenner, 2005). Streptococcus pyogenes natural habitat is the human body, being found in the upper respiratory tract, digestive tract, oral cavity and on the skin (4). It is when defenses are weak or when Streptococcus pyogenes is able to penetrate through these defenses can it cause infectious diseases. (4). The pathogen is airborne so a person with…

A 36 year-old man presented with three weeks history of enlarging left neck swelling, which was mildly painful. There was no prior history of upper respiratory tract infection. Clinical examination revealed a 5 cm x 5 cm cystic mass at the level II of left neck anterior to sternocleidomastoid muscle. It was soft, mobile, and tender on palpation with normal overlying skin. Nasal endoscopy did not detect any abnormality then. The total white cells count was raised at 12,000/mm3. He was diagnosed…

future occurrences. Over 200 viruses can cause the common cold. The most common viruses are rhinovirus, coronavirus, and respiratory syncytial virus. Rhinovirus, which causes up to forty percent of colds, is the major cause for upper and lower respiratory tract infections. Coronavirus, also a cause for respiratory tract infections, causes around twenty percent of colds; and respiratory syncytial virus causes ten percent. Colds begin when a virus…
