Complaints: Fever, swelling around operation wound
Specimen: Wound swab
Diagnosis: Wound infection

A wound infection happens when pathogens enter an open wound of the patient. Factors such as disease, surgery and weak immune system increase the patient’s risk of getting wound infection. Signs and symptom of a wound infection includes:
-Redness or swelling around the wound
-Secretion of Pus or watery discharge around the wound area
-foul odour from the wound
-mild fever

Possible pathogens that cause wound infection:
-Corynebacterium diphtheriae
-Pseudomonas aeruginosa
-staphylococcuss aureus
-Proteus mirabilis

Corynebacterium diphtheriae: C. diphtheriae is a facultative anaerobic, gram positive organism that can infect skin lesions in people with poor skin hygiene, causing cutaneous diphtheria. Symptom of cutaneoud diphtheria includes mild fever and swollen wound.

Pseudomonas aeruginosa: Pseudomonas aeruginosa is an aerobic, gram negative rod shape bacterium that can cause burn infection and wound infection. The microorganism is able to produce endotoxin that causes fever.

Staphylococcuss aureus: Staphylococcuss aureus is a facultative, gram positive coccus organism that causes localised infection in forms of abscess and skin infection, which is one of the possible causes to surgical wound infections.

Proteus mirabilis: Proteus mirabilis is A facultative, gram negative rod proteus species that cause uriniry tract infection, but it can also cause wound infection, mostly in hospitalized patients.

Laboratory diagnosis:
-Gram stain
-Culture (aerobic/anaerobic)
-biochemical reactions
-oxidase tests
-catalase tests
-antibiotic susceptibility
