Similar to septicemic plague, the untreated mortality rate of primary pneumonic plague is 100% [97,104]. Secondary pneumonic plague occurs among approximately 12% of individuals with bubonic plague or primary septicemic plague following the hematogenous spread of Y. Similar lesions and clinical syndromes may be seen with ulceroglandular tularemia (which raises similar concerns in regards to bioterrorism and is managed with comparable antimicrobial agents), epidemic typhus, suppurative infections (e. The lesions of chancroid, lymphogranuloma venereum, syphilitic lymphadenitis, and mycobacterial disease may be grossly similar but present in a more subacute manner and generally without the severe illness and prostration seen with plague. Conversely, the diagnosis of pneumonic and septicemic plague can be markedly more difficult given the absence of distinctive clinical findings. The radiographic findings of pneumonic plague are nonspecific, although the absence of mediastinal widening may help distinguish it from inhalational anthrax. The presence of the characteristic gram-negative rods in the sputum of an immunocompetent patient, particularly with a suitable exposure history, must raise the concern for plague. Exposure history, purpura fulminans, septic shock, and acral gangrene are all consistent but strongly resemble the syndromes seen with meningococcemia; rickettsioses; and pneumococcal and pseudomonal sepsis [5,86,89,97,104,112]. Laboratory Diagnosis A mild-to-moderate leukocytosis with neutrophil predominance and toxic granulations are seen in all forms of plague. In severe cases, elevated transaminases, azotemia, and coagulopathy with disseminated intravascular coagulation are seen. Gram stains of sputum; blood; or lymph node aspirates may show typical enteric gram-negative bacilli with bipolar staining, similar to Escherichia coli, Klebsiella, and other Enterobacteriaceae. Microscopic examination of a sputum specimen prepared with Wright–Giemsa stain will show the characteristic bipolar staining pattern more clearly. Rapid diagnostic assays using monoclonal antibodies to the F1 capsular antigen show promise for the early on-site diagnosis of plague [116,117], as do monoclonal antibodies directed at detection of Y. Plague should be suspected among persons with symptoms of fever and lymphadenopathy if they reside in, or have recently travelled to , a plague- endemic area and if gram-negative and/or bipolar-staining coccobacilli are seen on a smear taken from affected tissues. The diagnosis of plague should be presumed if immunofluorescence staining of smear or material is positive for the presence of Y. Plague as a bioterrorism agent should be suspected when multiple cases of severe and rapidly progressive pneumonic plague cases are seen with fulminant systemic symptoms and hemoptysis. Although pretreatment specimens should be obtained when possible, treatment of suspected plague should not be delayed while awaiting confirmatory results.

Despite administration of high-dose penicillin, the patient suffered grand mal seizures, hypotension, acidosis, and renal failure. Other findings included 50 mL gross blood in the mediastinum and several enlarged lymph nodes (1 cm–2 cm). Index case of fatal inhalational anthrax due to bioterrorism in the United States. In patients with a febrile illness or cutaneous lesions of unclear cause, an exposure and occupational history may be particularly helpful in focusing on the possibility of anthrax. During the 2001 bioterror attack in the United States, early recognition of the index case (case 13. Unfortunately, several other physicians failed to recognize the early manifestations of inhalation anthrax in postal workers, and those patients were discharged from the emergency room only to return later with full-blown fatal disease. The earlier recognition of several cutaneous anthrax cases could have alerted the authorities in New York in a more timely manner that a bioterror attack had also been launched in that state. Because the patient failed to seek medical attention during the early phase of his illness, his fatal outcome could not have been prevented. First Phase From 1 to 5 days after inhalation of spores, the patient has symptoms suggestive of a viral syndrome: nonproductive cough, malaise, fatigue, myalgia, and mild fever. Rhonchi may be heard on examination, but aside from fever, no other abnormal physical findings are observed. Second phase follows after a brief asymptomatic period and can include: a) Sudden onset of severe respiratory distress, fever, tachycardia, and tachypnea. It is during this period that spores are being transported by pulmonary macrophages from the lung parenchyma to the mediastinal lymph nodes. At this stage, antibiotic treatment should prevent progression to the second phase. Second Phase Within 2-4 days, symptoms temporarily resolve, but are rapidly followed by the second, more severe, stage of the disease. At this time, the spores have germinated in the mediastinal lymph nodes, and protective antigen, lethal factor, and edema factor are being produced by rapidly multiplying anthrax bacilli. Necrosis and hemorrhagic inflammation quickly develop, causing the sudden onset of severe respiratory distress with dyspnea, cyanosis, and diffuse diaphoresis accompanied by fever, tachycardia, and tachypnea.

This has been found to be useful in some patients in whom the coronary buttons are difficult to mobilize.
