Presentation
Occasional islands of regenerating epidermis were present under a necrotic layer of eschar tissue, superficially lining the prominently edematous viable tissue (Figure 2). [archivesofpathology.org]
Fever rarely occurs with cutaneous anthrax infections. [6] Gastrointestinal Gastrointenstinal anthrax presents itself initially with nausea, vomiting and anorexia, and fever. [microbewiki.kenyon.edu]
We found no examples of “missing epitopes” of the type we had expected, that is, ones present in the context of vaccination but lost upon infection. [jimmunol.org]
The clinical presentations as discussed herein are primarily from reports of anthrax in previously healthy adults. [ncbi.nlm.nih.gov]

Immune System
- Axillary Lymphadenopathy
When admitted to a hospital in Johannesburg, her left arm and hand were massively swollen with painful left axillary lymphadenopathy. Her temperature never exceeded 37.8°C. [ncbi.nlm.nih.gov]
Entire Body System
- Fatigue
The initial symptoms our non-specific and can make it difficult to diagnose, resulting in a high mortality rate. [6] Inhalation If infected with inhalation anthrax, the first symptoms are flu-like and include fever, malaise, cough, and fatigue. [microbewiki.kenyon.edu]
Symptoms include fever, shortness of breath, cough, fatigue, and chills. This can last hours to days. [en.wikipedia.org]
[…] well-defined and has ranged from 1 to 43 days, which may reflect delayed germination of inhaled spores or repeated inhalation of spores from the environment after the original exposure event. 8 Initial nonspecific signs and symptoms may include mild fever, fatigue [ncbi.nlm.nih.gov]
- Malaise
Symptoms of inhalation anthrax: Begins with fever, malaise, headache, cough, shortness of breath, and chest pain Fever and shock may occur later Symptoms of gastrointestinal anthrax usually occur within 1 week and may include: Abdominal pain Bloody diarrhea [account.allinahealth.org]
The initial symptoms our non-specific and can make it difficult to diagnose, resulting in a high mortality rate. [6] Inhalation If infected with inhalation anthrax, the first symptoms are flu-like and include fever, malaise, cough, and fatigue. [microbewiki.kenyon.edu]
The lesion is typically painless and can be accompanied by fever, malaise, headache, and painful lymphadenopathy. 12, 18 The mortality rate for cutaneous anthrax is less than 1% if treated with antimicrobial agents but can be as high as 20% if untreated [ncbi.nlm.nih.gov]
- Hunting
In the Serengeti ecosystem of Northern Tanzania, serological reactions have been reported in herbivorous species often hunted for bushmeat that comes from wildlife which is smuggled in for human consumption [ 26 ]. [royalsocietypublishing.org]

- Wound Infection
Wound cultures showed only the presence of viridans streptococci, bacteria that are not implicated in wound infections. The patient was treated with intravenous ciprofloxacin, gentamicin, tetracycline, flucloxacillin, and topical mupirocin. [ncbi.nlm.nih.gov]
- Edema of the Finger
On February 4, her general condition was excellent; the edema had diminished. A painless necrotic lesion on the left fourth finger measured 3 cm 2 ( Figure ). [ncbi.nlm.nih.gov]
Cardiovascular
- Thrombosis
Foci of thrombosis were noted. The Gram stains of the tissue, performed with different levels of intensity, revealed a focal group of partly stained Gram-positive, spore-forming, rod-shaped microorganisms, suggestive of B anthracis. [archivesofpathology.org]
Skin
- Ulcer
A swab of the patient's skin ulceration grew coagulase-negative Staphylococcus species but did not grow Bacillus anthracis, for which it was specifically examined. [archivesofpathology.org]
It begins as a raised itchy bump resembling an insect bite, which then develops into a vesicle (blister), then into a painless ulcer with a characteristic black area in the centre (see image). [sahealth.sa.gov.au]
A specimen may be obtained from the ulcer and cultured on sheep blood agar and then Gram-stained to demonstrate the organism. [6] Gastrointestinal To diagnose gastrointestinal anthax, it must be distinguished from dysentery. [microbewiki.kenyon.edu]
Anthrax infection in humans can occur through contact with sick animals or their products. 1 Patients with cutaneous anthrax may present with skin necrosis, ulceration, extensive edema in the surrounding tissues, toxemia and other symptoms. [ncbi.nlm.nih.gov]
This sore may blister and form a black ulcer (sore or eschar). The sore is usually painless, but it is often surrounded by swelling. A scab often forms, and then dries and falls off within 2 weeks. Complete healing can take longer. [account.allinahealth.org]

- Unable to Walk
The owner of the restaurant, who was one of the four patients, had purchased a head of sick cattle that was unable to walk from a local farmer at a cheap price, and it was immediately slaughtered at the restaurant. [ncbi.nlm.nih.gov]

Skin Test
- Skin Test Positive
In contrast, the same research previously demonstrated that >90% of cutaneously infected individuals remained skin test positive a year postinfection ( 43 ). [jimmunol.org]
Microbiology
- Bartonella Henselae
Serologic test results for rickettsiae, orthopoxviruses, and Bartonella henselae were negative. The patient was not immunocompromised. [ncbi.nlm.nih.gov]

HLA Type
- HLA-DR1
The epitope that we had picked up predominantly in the response of infected individuals, LF 714–733, also bound to HLA-DR1, 4, 7, 11, and 15, whereas there was no detectable binding to HLA-DR3 or 13. [jimmunol.org]
- HLA-DR3
The epitope that we had picked up predominantly in the response of infected individuals, LF 714–733, also bound to HLA-DR1, 4, 7, 11, and 15, whereas there was no detectable binding to HLA-DR3 or 13. [jimmunol.org]
Treatment
Because of timely treatment, the four patients fully recovered in a short time without complications. All of the patients returned home after treatment. [ncbi.nlm.nih.gov]
Deaths from cutaneous anthrax are rare with appropriate antibiotic treatment. [sahealth.sa.gov.au]
Without treatment, about 20% of cutaneous skin infection cases progress to toxemia and death. [en.wikipedia.org]

Outlook (Prognosis) When treated with antibiotics, cutaneous anthrax is likely to get better. But some people who do not get treated may die if anthrax spreads to the blood. [account.allinahealth.org]

In some situations preventative antibiotics may also be given to people who are suspected to have been exposed to anthrax spores. Prevention Control of anthrax in livestock herds is essential for prevention of its spread to humans. [sahealth.sa.gov.au]
Although it is a rare disease in humans, anthrax should be considered in the differential diagnosis of preseptal cellulitis to save the life and prevent serious complications. [journals.lww.com]
