Which type of anthrax is more common in animals and in humans?
a. Cutaneous anthrax
b. Inhalation anthrax
c. Gastrointestinal anthrax
d. Mucoid anthrax

Verified step by step guidance

1. Understand the different types of anthrax infections: cutaneous, inhalation, gastrointestinal, and mucoid anthrax. Each type refers to the route of infection and the symptoms presented.
2. Recall that cutaneous anthrax occurs when Bacillus anthracis spores enter the body through cuts or abrasions on the skin, leading to localized skin lesions. This is the most common form in both animals and humans.
3. Recognize that inhalation anthrax results from inhaling spores, leading to severe respiratory illness, but it is less common compared to cutaneous anthrax.
4. Note that gastrointestinal anthrax occurs from ingesting contaminated meat, which is less frequent than cutaneous anthrax.
5. Identify that mucoid anthrax is not a standard classification of anthrax types, so it can be excluded from consideration.

Key Concepts

Types of Anthrax

Anthrax is an infection caused by Bacillus anthracis and manifests in several forms: cutaneous, inhalation, gastrointestinal, and rarely mucoid. Each type differs by the route of entry and symptoms, with cutaneous anthrax being the most common form in both animals and humans.

Cutaneous Anthrax

Cutaneous anthrax occurs when spores enter the skin through cuts or abrasions, causing localized skin lesions. It is the most frequent form of anthrax, especially in animals and humans exposed to infected animals or animal products, and is generally less severe than inhalation or gastrointestinal forms.

Epidemiology of Anthrax in Animals and Humans

Anthrax primarily affects herbivorous animals, which are infected through soil containing spores. Humans usually contract anthrax through direct contact with infected animals or their products, making cutaneous anthrax the most common type due to skin exposure during handling.
