The organism is a saprophyte living in the soil. Infection may be subclinical, acute, subacute, or chronic. Pulmonary infection is most common. Histologically, the acute illness is represented by lung abscesses and the subacute form by caseation necrosis. Upper lobe cavities must be distinguished from those caused by tuberculosis. Debilitated patients may develop hematogenous spread of the organism to other organs. Skin lesions from direct inoculation cause suppurative lesions often in association with nodular lymphangitis and regional …

Risk factors for infection include a CD4 count of < 100 cells/mL3, neutropenia or functional neutrophil defects, intravascular catheterization, hospitalization, and prior use of antibiotics including ciprofloxacin or trimethoprim-sulfamethoxazole. Many cases are community acquired. Bacteremia is common, and the lung or an intravenous catheter is the most frequent portal of entry. An impaired ability to mount immunotype-specific antibodies to Pseudomonas lipopolysaccharide antigen has been noted in HIV-positive individuals with bacteremia. Relapse is frequent, and mortality is high, 40%. Pneumonia is usually associated with cavitation and a high relapse rate. …

Patients are asymptomatic during the incubation phase. Early in the course of disease, patients may experience diarrhea or constipation. Patients then develop a variety of nonspecific symptoms, such as fever, chills, weakness, malaise, myalgia, and cough. Signs, that are not always present, such as rose spots, paroxysmal bradycardia in sharp contrast to the clinical presentation and elevated temperature, and hepatosplenomegaly are clues to the diagnosis. Profound mental status changes and picking at bed clothing, termed typhoid psychosis, may develop in some patients with enteric fever. The middle phase of disease is the …

Enteric fever. • Enteric fever is a systemic disease that may or may not be preceded by a diarrheal illness. • Key signs and symptoms include possible diarrhea or constipation that precedes constitutional symptoms and possible hepatosplenomegaly; other signs and symptoms may include “rose spots,” paroxysmal bradycardia, and mental status changes (so called “typhoid psychosis”). • Enteric fever is usually associated with the ingestion of water that has been contaminated by human feces. • “S typhi,” “S paratyphi,” or rarely other Salmonella “species” (see General Considerations section below for clarification of current …

Risk factors associated with Bacillus infection include the presence of intravascular catheters, intravenous drug use, sickle cell disease, and immunosuppression — particularly corticosteroid use, transplantation, AIDS, and neutropenia secondary to chemotherapy. The hardy growth characteristics of Bacillus spp. cause them to arise as common laboratory contaminants; however, they are also capable of causing severe invasive illness. B cereus and B subtilis are the most frequent Bacillus spp. to cause invasive infection. Pneumonia, meningoencephalitis, …

Signs and symptoms of early-onset group B streptococcal neonatal infection include lethargy, poor feeding, jaundice, abnormal temperature, grunting respirations, pallor, and hypotension. In most infants with pneumonia, symptoms of respiratory distress are present …

ENDOCARDITIS Viridans streptococci have a strong association with bacterial endocarditis (see site) (Box 1). A defectiva and A adjacens were once an important cause of culture-negative endocarditis. However, current laboratory media and techniques enable these “nutritionally variant streptococci” to be identified more readily. 2. BACTEREMIA Viridans streptococci account for 2.6% of positive blood cultures reported from clinical laboratories; however, of these, only about one-fifth are thought to be clinically significant (the remainder are attributed to contamination or transient bacteremia). Viridans streptococci are, however, one of the leading causes of …
