In severe cutaneous infection, 1 American Academy of Pediatrics, Committee on Infectious Diseases, Committee on Nutrition. In disseminated infection, hepatic and splenic abscesses can occur, and relapses are common without prolonged therapy. Additional members of the complex con- Burkholderia include Burkholderia pseudomallei, Burkholderia gladioli, and Burkholderia mallei (the agent responsible for glanders). Burkholderia thailandensis and Burkholderia oklahomensis are rare human pathogens. Depending on the species, transmission may occur from other people (person to person), from contact with contaminated fomites, and from exposure to environmental sources. The source of acquisition of B cepacia complex by patients with B cepacia complex most often is associated with contamination of disinfectant solutions used to clean reusable patient equipment, such as bronchoscopes and pressure transducers, or to disinfect skin. In areas with highly endemic infection, B pseudomallei is acquired early in life, with the with more than 75% of cases occurring during the rainy season. Disease can be acquired by direct inhalation of aerosolized organisms or dust particles containing organisms, by percutaneous or wound inoculation with contaminated soil or water, or by ingestion of contaminated soil, water, or food. People also can become infected as a result of laboratory exposures when proper techniques and/or proper personal protective equipment guidelines are not followed. Symptomatic infection can occur in children 1 year or younger, with pneumonia and parotitis reported in infants as young as 8 months; in addiB pseudomallei also has been reported to cause pulmonary infection in the incubation period can be prolonged (years). The likelihood of successfully isolating the organism is increased by culture of sputum, throat, rectum, and ulcer or skin lesion specimens. A direct polymerase chain reaction assay may provide a more rapid result than culture but is less sensitive, especially when performed on blood, and is not recommended for routine use as a diagnostic assay. Serologic testing is not adequate for tive result by the indirect hemagglutination assay for a traveler who has returned from an still requires isolation of B pseudomallei from an infected site. Other rapid assays are being developed for diagnosis of melioidosis but are not yet commercially available. Some experts recommend combinations of antimicrobial agents that provide synergistic activity against B cepacia complex. The majority of B cepacia complex isolates are intrinsically resistant to aminoglycosides and polymyxins. The drugs of choice for initial treatment of melioidosis depend on the type of clinical infection, susceptibility testing, and presence of comorbidities in the patient (eg, diabetes, invasive infection should include meropenem, imipenem, or ceftazidime (rare resistance) for a minimum of 10 to 14 days. Amoxicillin clavulanate and doxycycline are considered second-line oral agents and may be associated with a higher rate of relapse. Prevention of infection with B pseudomallei in areas with endemic disease can be difwater in these areas, and it is recommended that they stay inside during weather that could result in aerosolization of the organism. Wearing boots and gloves during agriculbe educated regarding their risk for infection when traveling to regions where B pseudomallei is endemic. In neonates and young infants, bloody diarrhea without fever can be the only manifestation of infection. Pronounced fevers in children can result in febrile seizures that can occur before gastrointestinal tract symptoms. Abdominal pain can mimic that produced by appendicitis Bacteremia is uncommon but can occur in elderly patients and in patients with underlying conditions. Immunocompromised hosts can have prolonged, relapsing, or extraintestinal infections, especially with Campylobacter fetus and other Campylobacter species. Other Campylobacter species, including Campylobacter upsaliensis, Campylobacter lari, and Campylobacter hyointestinalis, can cause similar diarrheal or systemic illnesses in children. The gastrointestinal tracts of domestic and wild birds and animals are reservoirs of the bacteria. C jejuni and C coli have been isolated from feces of 30% to 100% of healthy chickens, turkeys, and water fowl. Many farm animals, pets, and meat sources can harbor the organism and are potential sources of infection. Transmission of C jejuni and C coli occurs by ingestion of contaminated food or water or by direct contact with fecal material from infected animals or people. Improperly cooked poultry, untreated water, and unpasteurized milk have been the main vehicles of transmission.

Another option is to take a shorter history by asking the patient to list only the prior jobs that involved the agents of interest. For example, one could ask for all current and past jobs involving pesticide exposure. Established in 1998, the Initiative goal is to improve the recognition, diagnosis, treatment, and prevention of pesticide-related illnesses. As a framework to achieve this goal, the Initiative developed a set of practical skills to guide students, nurses and practicing clinicians in recognizing and managing pesticide-related illnesses. These skills and competencies can be integrated into existing education and training of healthcare providers to facilitate the effective management of patients with suspected pesticide-related illnesses. This may be useful in raising the index of suspicion for pesticide toxicity where these signs and symptoms occur. Such suspicion can be evaluated further within the differential diagnosis as appropriate. It is important to keep in mind that the signs and symptoms listed have multiple causes, pesticidal and nonpesticidal. In addition, no specific symptoms or signs are invariably present in poisonings by particular pesticides. This complexity may explain why many poisonings are characterized by unexpected or atypical manifestations. The table does not differentiate clinical presentation by route of exposure or dosage.
