Tetanus is caused by the tetanus bacterium, Clostridium tetani. [1] 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).
Fused tetanus is when there is no relaxation of the muscle fibers between stimuli and it occurs during a high rate of stimulation. [5] A fused tetanic contraction is the strongest single-unit twitch in contraction. [6] When tetanized, the contracting tension in the muscle remains constant in a steady state. This is the maximal possible ...
Neonatal tetanus (trismus nascentium) is a form of generalised tetanus that occurs in newborns. Infants who have not acquired passive immunity from an immunized mother are at risk. It usually occurs through infection of the unhealed umbilical stump, particularly when the stump is cut with a non-sterile instrument.
Tetanus is often referred to as lockjaw due to the fact that the bacteria the causes it (Clostridium tetani) cause the muscles of the jaw to tighten which makes the infected person unable to open their mouth. Today in the United States, tetanus is an uncommon disease with an average of only 29 cases reported per year between 1996 and 2009.
The term childhood disease refers to disease that is contracted or becomes symptomatic before the age of 18 or 21 years old. Many of these diseases can also be contracted by adults. Some childhood diseases include:
Legionnaires' disease, E-coli, tetanus among health threats after tropical storms. ... animal and human waste and harmful chemicals. ... Mold exposure can lead to a number of symptoms including ...
During pregnancy, hepatitis A can cause placental abruption, premature rupture of membranes, and increased rates of preterm labor. [20] Hepatitis B is an enveloped, double stranded DNA virus that is spread by exposure to blood, with the main modes of transmission are blood, sexual transmission, or perinatal. During pregnancy, acute hepatitis B ...
A man suffering muscle spasms from tetanus, painted by Charles Bell in 1809. While C. tetani is frequently benign in the soil or in the intestinal tracts of animals, it can sometimes cause the severe disease tetanus. Disease generally begins with spores entering the body through a wound. [5]
