Captive coyotes (Canis latrans) were inoculated intragastrically (1 coyote), and intratracheally (6 coyotes) with Histoplasma capsulatum to simulate natural routes of exposure. In addition, the infectious organism was inoculated IV into another coyote and into a dog (C familiaris) to simulate hematogenous dissemination of H capsulatum. Isolation of the pathogen from various tissue specimens, using direct plating and mouse inoculation methods, provided mycologic evidence of infection. The presence of anti-Histoplasma serum antibodies also was monitored. Of the 6 coyotes challenged intratracheally, one developed a benign pulmonary form of histoplasmosis. This coyote developed a transient
cough
, and intracellular yeasts typical of H capsulatum were observed microscopically in pulmonary tissue specimens. The pathogen was isolated from specimens of pulmonary tissue and associated lymph nodes. The coyote that was fed Histoplasma-infected mice (intragastric challenge) did not develop clinical disease. The coyote and the dog inoculated IV developed a multifocal, nonsuppurative infection, without clinical evidence of histoplasmosis. Pathologic findings in the coyote and dog were similar; both animals had
splenitis
, lymphadenitis, and petechiation of the lungs. The liver and spleen were considered the primary extrapulmonary target organs on the basis of mycologic and histologic findings.

An 8-year-old male rhesus monkey (Macaca mulatta) died following a 6-day illness consisting of progressive depression, anorexia, labored abdominal breathing,
coughing
, and tachypnea. Gross necropsy findings included severe multifocal (miliary) granulomatous pneumonia, granulomatous
splenitis
, and multifocal cerebral abscesses. Histologic examination revealed 10-15-microm broad-based budding organisms within pyogranulomatous inflammatory lesions in the lung, tracheobronchial lymph node, brain, spleen, and liver. The distribution of extrapulmonary lesions was intermediate between that described for dogs and that described for humans. These findings were consistent with blastomycosis, which is previously unreported in nonhuman primates.

BACKGROUND Bartonella infection is the causative organism of cat-scratch disease (CSD), which typically presents with self-limited localized lymphadenopathy. In HIV-infected patients, Bartonella infection can cause systemic illnesses with significant morbidity and mortality manifesting as bacillary angiomatosis (BA), hepatic peliosis,
splenitis
, bacteremic febrile illness, and other organ involvement. To the best of our knowledge, there have been no reports of HIV-infected patients presenting with generalized lymphadenopathy caused by Bartonella infection. We report an unusual case of CSD presenting with generalized lymphadenopathy in an AIDS patient with advanced immunosuppression. CASE REPORT A 44-year-old woman with AIDS, advanced immunosuppression, and intermittent adherence to antiretroviral therapy and medical care, presented with
cough
and increased generalized tender lymphadenopathy. A lymph node biopsy 1 year earlier was non-diagnostic for tuberculosis, fungal infection, and lymphoproliferative disorders. She remained with generalized lymphadenopathy. A repeat biopsy with the addition of Warthin-Starry silver staining suggested the diagnosis of cat-scratch lymphadenitis. She responded well to a long course of azithromycin antibiotic therapy, with the resolution of lymphadenopathy. CONCLUSIONS Cat-scratch disease may present with prolonged generalized lymphadenopathy, an unusual presentation in HIV patients with advanced immunosuppression. Awareness of the possibility of CSD in a similar clinical scenario may prompt early recognition and management of this disease.
