Subterminal endospores are those between these two extremes, usually seen far enough towards the poles but close enough to the center so as not to be considered either terminal or central. Lateral endospores are seen occasionally. Examples of bacteria having terminal endospores include Clostridium tetani, the pathogen that causes the disease ...
The disease is an international health problem, as C. tetani endospores are ubiquitous. Endospores can be introduced into the body through a puncture wound (penetrating trauma). Due to C. tetani being an anaerobic bacterium, it and its endospores thrive in environments that lack oxygen, such as a puncture wound. With the changes in oxygen ...
Clostridium endospores have a distinct bowling pin or bottle shape, distinguishing them from other bacterial endospores, which are usually ovoid in shape. [citation needed] The Schaeffer–Fulton stain (0.5% malachite green in water) can be used to distinguish endospores of Bacillus and Clostridium from other microorganisms. [12]
Although S. epidermidis is not usually pathogenic, patients with compromised immune systems are at risk of developing infection. These infections are generally hospital-acquired. [4] S. epidermidis is a particular concern for people with catheters or other surgical implants because it is known to form biofilms that grow on these devices. [5]
Meet the expert: Infectious disease expert Amesh A. Adalja, MD, is a senior scholar at the Johns Hopkins Center for Health Security. What are the first symptoms of norovirus? Norovirus tends to ...
Cryptosporidiosis, sometimes informally called crypto, [1] is a parasitic disease caused by Cryptosporidium, a genus of protozoan parasites in the phylum Apicomplexa.It affects the distal small intestine and can affect the respiratory tract in both immunocompetent (i.e., individuals with a normal functioning immune system) and immunocompromised (e.g., persons with HIV/AIDS or autoimmune ...
In the early 1900s, researchers were trying to find alternative methods to improve disease and infection from these endospores. [3] In 1922, Dorner published a method for staining endospores. He found a differential staining technique where endospores appear green and vegetative cells appear pinkish red. [4]
The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
