Congratulations! You have correctly identified the bacteria.

The BLAST search displays the matching sequences in the database in descending order of the degree of the match. Most of the top scorers are either Bartonella henselae or Rochalimaea henselae. The latter is an older name for this species. Bartonella species are demanding in their nutritional requirements for culture; as a result, normal culturing techniques do not yield vigorously growing bacterial colonies.

Here is the description of this species from our reference section:

Bartonella henselae Various species of Bartonella that are pathogenic to humans are transmitted via a vector, or directly from an animal reservoir. For example, B. bacilliformis via sandflies causes Oroya fever; B. quintana via body lice causes trench fever; and B. henselae via cats causes cat scratch disease (CSD). CSD typically manifests as swellings of the lymph glands, possibly with skin lesions at the site of inoculation and possibly accompanied by fever, fatigue, and other symptoms. Immunocompromised patients may be particularly susceptible and can develop a different disease, bacillary angiomatosis, as a result of infection by B. henselae or B. quintana.

This concludes Sample A.
