The onset of symptoms is typically 3 to 21 days following infection. Recovery may take months; about 10% of cases prove to be fatal. [1] C. tetani is commonly found in soil, saliva, dust, and manure. The bacteria generally enter through a break in the skin, such as a cut or puncture wound caused by a contaminated object.
Additionally, any surgical wound where there is a major break in sterile technique or obvious contamination from the gastrointestinal tract is considered a contaminated wound. Class 4 – dirty/infected: a wound with evidence of an existing clinical infection. Class 4 wounds are usually found in old traumatic wounds which were not adequately ...

It is categorized into four subtypes, with the first two being the most common. Type 1 requires an infection with an anaerobe and a species in the Enterobacteriaceae family, while type 2 is characterized by infection with Streptococcus pyogenes, a Gram-positive cocci bacteria, and thus is also known as hemolytic streptococcal gangrene.

Horses may acquire cellulitis, usually secondarily to a wound (which can be extremely small and superficial) or to a deep-tissue infection, such as an abscess or infected bone, tendon sheath or joint. [33] [34] Cellulitis from a superficial wound usually creates less lameness (grade 1–2 of 5) than that caused by septic arthritis (grade 4–5 ...
Buboes are a symptom of bubonic plague and occur as painful swellings in the thighs, neck, groin or armpits. [2] They are caused by Yersinia pestis bacteria spreading from flea bites through the bloodstream to the lymph nodes, where the bacteria replicate, causing the nodes to swell. [3]
Some colonizing bacteria, such as Corynebacteria sp. and Viridans streptococci, prevent the adhesion and colonization of pathogenic bacteria and thus have a symbiotic relationship with the host, preventing infection and speeding wound healing. This image depicts the steps of pathogenic infection. [18] [19] [20]
These lesions are often infected by pathogenic bacteria such as Staphylococcus intermedius. [39] Horses that lick wounds may become infected by a stomach parasite, Habronema, a type of nematode worm. The rabies virus may be transmitted between animals, such as the kudu antelopes by wound licking of wounds with residual infectious saliva. [40]
