Final answer:
Multifilament sutures are considered less appropriate in the presence of infection because their braided structure can harbor bacteria.
Step-by-step explanation:
The type of sutures that are braided and generally considered less appropriate in the presence of infection are multifilament sutures. Multifilament sutures consist of multiple strands of material, such as silk or nylon, intertwined together. The braided structure of these sutures creates small spaces where bacteria and other microorganisms can hide, increasing the risk of infection. In contrast, monofilament sutures, which are made of a single strand of material, are less likely to harbor bacteria and are usually preferred in the presence of infection.
