On day 11 of illness, we started administering rifampin and doxycycline for a possible CSD diagnosis; the patient was positive for B. henselae IgG (1:152) and IgM (1:160).
Rarely, B. henselae results in culture-negative endocarditis, an illness that can be difficult to diagnose and a challenge to treat effectively and in a timely manner.
B. henselae infections are thought to occur when a human is bitten or scratched by an infected cat [2-4] and may be transmitted by cat fleas or by an infected cat licking the nonintact skin of a human [5-7].
High B. henselae IgM titer is an indicator of acute infection and values typically return to normal within 3 months.
B. henselae is the aetiological agent of cat-scratch disease, bacillary angiomatosis, meningo-encephalitis and chronic bacteraemia.
This is due to secondary infection with B. henselae or a similar organism, Rochalimaea henselae.
There's no good evidence that fleas can transmit B. henselae directly to humans, however.
His serologic titer for B. henselae obtained on day 14 of illness was 1:4096.
Among the Bartonella species, B. henselae is known as one of the most noteworthy pathogens (1).
