Salmonella sp., Campylobacter jejuni for gastrointestinal tract.

Infections mostly affect the respiratory tract (nose, sinuses, bronchi, lungs) and the gastrointestinal tract; they can also occur at other sites, such as the eyes, skin, and ears. These infections respond to antibiotics but can recur upon discontinuation of antibiotics. Bronchiectasis can develop when severe, recurrent pulmonary infections are left untreated.
