This neonate is displaying a bodily rigidity produced by Clostridium tetani exotoxin, called “neonatal tetanus”. Neonatal tetanus occurs in infants born without protective passive immunity, because the mother is not immune. It usually occurs through infection of the unhealed umbilical stump, particularly when the stump is cut with an unsterile instrument.

Lockjaw symptoms are caused due to Clostridium tetani infection. Damaged upper motor neurons cause muscular rigidity leading to Lock-jaw.

Clostridium tetani

  • General information

    • the following information is not yet verified
      Taxonomy
      Family: Clostridiaceae

      Natural habitats
      C. tetani and his spores can be isolated from a variety of sources, including soil and the intestinal contents of numerous animal species.

      Clinical significance.
      Tetanus, caused by C. tetani, is often associated with puncture wounds that do not appear to be infected.

      A potent neurotoxin, often referred to as tetanospasmin, is elaborated at the site of trauma and rapidly binds to neural tissue, provoking a characteristic paralysis and tonic spasms.

      Tetanus,
      also known as lockjaw, is an infection characterized by muscle spasms.
      In the most common type the spasms begin in the jaw and then progress to the rest of the body.
      These spasms usually last a few minutes each time and occur frequently for three to four weeks.

      Other symptoms may include: fever, headache, trouble swallowing, high blood pressure, and a fast heart rate.

      Onset of symptoms is typically three to twenty one days following infection. It may take months to recover.

      About 10% of those infected die.

      Gram positive (become Gram negative after 24 h incubation) straight rods,

  • Culture characteristics

    • the following information is not yet verified

      Obligate anaerobic

      BBAØ
      Colonies are 4-6 mm in diameter, flat, translucent, gray, with a matt surface, irregular and rhizoid margins and usually cause

      a narrow zone of beta-hemolysis.

      There is a tendency to swarm, a thin film of growth over entire agar plate, that is more marked on moist plates.
