meningitis and other infections (Andes and Casadevail‚ 2013). Causative agent: Exserohilum rostratum Although there were a few different fungal species identified during the outbreak‚ Exserohilum rostratum was the pre-dominant disease causing pathogen. This came as a shock to many medical and scientific personnel because Exserohilum rostratum is a species with very low pathogenicity‚ which means it was never really a problem to humans and even

If the pond is too shallow than the freezing and evaporating point of the pond will fluctuate too much for the duckweed to grow. Duckweed is composed of a think cell wall‚ with chloroplasts‚ mitochondria‚ smooth ER‚ Rough ER‚ a vacuole‚ cytoplasm‚ goolgi body‚ nucleus‚ nucleolus. All these parts in duckweed help the plant carry

1. Hemostasis Hemostasis is the first stage of acute wound healing. It is characterized by the formation of a primary plug to prevent any further blood loss and exposure to environmental pathogens. Once the tissue has been injured‚ the vascular and lymphatic vessels that are disrupted become constricted. The reparative coagulum is initiated as platelets adhere to the interior surfaces of the vessels as well as to a newly forming matrix of fibrin that together become the cruor of the thrombus‚ thus

classified as Group D Streptococcus until 1984 when genomic DNA analysis showed that a separate genus classification would be appropriate. Enterococci are part of the normal intestinal flora (good bacteria) of humans and animals but are also important pathogens responsible for serious infections. They are considered gram-positive‚ meaning they stain dark blue or violet. They also mostly occur in pairs or short chains. Enterococci are facultative anaerobic organisms‚ meaning they can thrive in both oxygen

also helps to regulate the temperature of the body and skin‚ which means it helps in homeostasis. There are many different functions of the skin. Firstly‚ it acts as chemical and physical barrier for the body‚ protecting us against from harmful pathogens from the external environment. It also gives us sensation‚ due to the nerves in the skin. If the skin is harmed from heat‚ the nerves attached to the skin will send neurotransmitters to the central nervous system which will cause a response by moving

start of the 20th century‚ probiotics were thought to beneficially affect the host by improving its intestinal microbial balance‚ thus inhibiting pathogens and toxin producing bacteria.[3] Today‚ specific health effects are being investigated and documented including alleviation of chronic intestinal inflammatory diseases‚[4] prevention and treatment of pathogen-induced diarrhea‚[5] urogenital infections‚[6] and atopic diseases.[7] To date‚ the European Food Safety Authority has rejected most claims

Influenza virus is one of the well-explored the pathogens and development of flu vaccine is considered as the most efficient strategy to defense the outbreak. However‚ the variability of the antigen and rapid reassortant of the genetic segments weakens flu vaccine effectiveness. And the protection of flu vaccine could not contribute to clinical treatment when the patients suffer from severe illness. Therefore‚ the study of the interaction between pathogen and host immune response is needed. The Hannover
