Brucellaceae
A family of bacteria that includes the genus Brucella''
Overview[edit | edit source]
The Brucellaceae is a family of Gram-negative bacteria within the order Rhizobiales. This family is notable for including the genus Brucella, which contains several species that are pathogenic to humans and animals. Members of the Brucellaceae family are small, non-motile, and facultatively intracellular pathogens.
Characteristics[edit | edit source]
Brucellaceae are characterized by their small, coccobacillary shape and their ability to survive and replicate within host cells. They are aerobic and do not form spores. The bacteria are known for their slow growth and require complex media for cultivation in laboratory settings.
Pathogenicity[edit | edit source]
The genus Brucella is the most well-known member of the Brucellaceae family due to its role in causing brucellosis, a zoonotic infection that affects various animal species and can be transmitted to humans. Brucellosis is characterized by fever, sweats, malaise, anorexia, headache, and muscle pain. In animals, it can cause reproductive issues such as abortion and infertility.
Transmission[edit | edit source]
Brucellaceae bacteria are typically transmitted through direct contact with infected animals or consumption of contaminated animal products, such as unpasteurized milk or undercooked meat. Occupational exposure is also a risk for individuals working in veterinary, laboratory, or agricultural settings.
Prevention and Control[edit | edit source]
Preventive measures for brucellosis include vaccination of livestock, pasteurization of dairy products, and the implementation of biosecurity measures in animal husbandry. In humans, avoiding consumption of raw dairy products and using protective equipment when handling animals can reduce the risk of infection.
Diagnosis and Treatment[edit | edit source]
Diagnosis of brucellosis involves serological tests, culture, and molecular methods to detect the presence of Brucella species. Treatment typically involves a combination of antibiotics, such as doxycycline and rifampin, over an extended period to prevent relapse.
