Coccidioidomycosis (/ k ɒ k ˌ s ɪ d i ɔɪ d oʊ m aɪ ˈ k oʊ s ɪ s /, kok-SID-ee-oy-doh-my-KOH-sis) is a mammalian fungal disease caused by Coccidioides immitis or Coccidioides posadasii. [3] It is commonly known as cocci, [4] Valley fever, [4] as well as California fever, [5] desert rheumatism, [5] or San Joaquin Valley fever. [5]
Brucellosis [4] is a zoonosis caused by ingestion of unpasteurized milk from infected animals, or close contact with their secretions. [5] It is also known as undulant fever, Malta fever, and Mediterranean fever. [6] The bacteria causing this disease, Brucella, are small, Gram-negative, nonmotile, nonspore-forming, rod-shaped (coccobacilli ...
Cocci can grow in pairs, chains, or clusters, depending on their orientation and attachment during cell division. In contrast to many bacilli-shaped bacteria, most cocci bacteria do not have flagella and are non-motile. [5] Cocci is an English loanword of a modern or Neo-Latin noun, which in turn stems from the Greek masculine noun κόκκος ...
Pathogenic bacteria are bacteria that can cause disease. [1] This article focuses on the bacteria that are pathogenic to humans. Most species of bacteria are harmless and many are beneficial but others can cause infectious diseases. The number of these pathogenic species in humans is estimated to be fewer than a hundred. [2]
Rheumatic fever, a disease that affects the joints, kidneys, and heart valves, is a consequence of untreated strep A infection caused not by the bacterium itself, but due to the antibodies created by the immune system to fight off the infection cross-reacting with other proteins in the body. This "cross-reaction" causes the body to essentially ...
It is the usual cause of the relatively rare bacterial disease listeriosis, an infection caused by eating food contaminated with the bacteria. The overt form of the disease has a case-fatality rate of around 20–30%. Listeriosis can cause serious illness in pregnant women, newborns, adults with weakened immune systems and the elderly, and may ...
Yersinia pestis (Y. pestis; formerly Pasteurella pestis) is a gram-negative, non-motile, coccobacillus bacterium without spores that is related to both Yersinia enterocolitica and Yersinia pseudotuberculosis, the pathogen from which Y. pestis evolved [1] [2] and responsible for the Far East scarlet-like fever.
The most common mode of entry of the bacteria into the body is through the injured skin coming in contact with soil or water containing the bacteria. [1] [9] The disease usually starts as a limited infection of the skin at the point of entry of the bacteria, which progresses to necrotizing metastatic lesions, then multiple abscesses of the ...
