The correct spelling of the bacterium that causes cat-scratch disease is "Bartonella henselae", pronounced as /bɑrtənɛlə hɛnsəli/. The first part, "Bartonella", is named after Alberto Barton, a Peruvian bacteriologist, and is pronounced as /bɑrtənɛlə/. The second part, "henselae", honors Diane Hensel, a microbiologist who identified the bacterium, and is pronounced as /hɛnsəli/. The phonetic transcription shows that the emphasis is on the second syllable of "Bartonella" and the first syllable of "henselae".
Bartonella henselae is a gram-negative bacterium that belongs to the genus Bartonella, a group of bacteria that are known to cause various diseases in humans. It is primarily transmitted to human beings through flea bites and scratches from infected cats, hence it is commonly referred to as "cat-scratch disease bacterium."
The bacterium has a curved, rod-shaped structure and is typically found in the bloodstream of infected cats. Although cats are the primary reservoir for Bartonella henselae, it has also been detected in various other animals, including dogs, rodents, and wild animals.
In humans, Bartonella henselae infection usually manifests as cat-scratch disease (CSD), characterized by swollen lymph nodes, fever, headache, and fatigue. CSD is typically a benign and self-limiting condition, but in some cases, it can lead to more severe complications, especially in individuals with a weakened immune system.
Diagnosis of Bartonella henselae infection is often based on clinical symptoms, although laboratory tests such as serology (blood tests) can be used to confirm the presence of antibodies against the bacterium. Treatment generally involves the use of appropriate antibiotics, such as azithromycin or doxycycline, to eliminate the infection.
Overall, Bartonella henselae is a bacterium that primarily causes cat-scratch disease in humans and is transmitted through contact with infected cats. It is important for individuals to take precautions when handling cats, especially if they show signs of illness, to reduce the risk of infection.
The word "Bartonella henselae" has its etymology rooted in the names of the individuals involved in its discovery and classification.
The genus name "Bartonella" is derived from the surname of American physician and researcher Albert Barton, who first identified the bacteria belonging to this genus. Albert Barton made significant contributions to the study of infectious diseases during the 19th century.
The species name "henselae" is a tribute to Diane Hensel, a microbiologist who played a crucial role in the identification and characterization of this particular species. Diane Hensel was a researcher at the Centers for Disease Control and Prevention (CDC) in Atlanta and was instrumental in elucidating the nature of this bacterium, particularly its association with cat-scratch disease.
Therefore, the etymology of "Bartonella henselae" is primarily based on the names of the scientists involved in its discovery and research.
