• abaca — A textile plant of the banana family (Musa textilis), cultivated in the Philippines, whose leaves yield a highly durable vegetable fiber (Manila hemp).

• abacterian — A medical term used to describe an environment, biological sample (urine, cerebrospinal fluid), or inflammatory process where no bacteria are present. An abacterial inflammation (such as abacterial cystitis or prostatitis) produces symptoms similar to an infection but is triggered by chemical, immune, traumatic factors, or viruses, with laboratory microbial cultures remaining negative.
• abacteriemic — A medical term describing the state of an organism or circulating blood in which no viable bacteria are present. It is used clinically to confirm the absence of a systemic infection disseminated through the bloodstream or to describe the complete remission phase of a patient successfully treated for bacteremia, where repeated blood cultures turn negative.
