Myositis and septicemia caused by Acinetobacter calcoaceticus were diagnosed in a mare. The infection was characterized clinically by ventral swelling and edema, diarrhea, listlessness, and rectal temperature of 39.4 C. The mare was treated symptomatically for 2 days but died on the 3rd day. Conditions seen at necropsy were myositis, enteritis, typhlitis, colitis, and hepatitis. Lymph nodes were moderately enlarged throughout the body. Gross lesions in musculature were edema, scarring, petechiae, and an occasional exxhymosis. The enteritis was catarrhal, with excessive mucus and moderate hyperemia. The typhlitis and colitis were hemorrhagic. The swollen liver had a diffuse mottled pale and red pattern. Microscopic lesions in skeletal muscle consisted of petechiation, necrosis, scarring, and edema. Cardiac muscle was also scarred and necrotic, but edema was not prominent. Periacinal necrosis was found in the liver. Acinetobacter calcoaceticus was isolated from myocardium and liver.

Fifteen chickens, five broilers and ten layers, from the Pennsylvania 1983 outbreak of highly pathogenic avian influenza virus infection, were examined. Gross lesions in the broilers were limited to serosal petechiae and dehydration. In the layers there was comb edema, vesiculation, and necrosis. Microscopic lesions were mild to severe diffuse nonsuppurative encephalitis, very mild to severe diffuse necrotizing pancreatitis, and very mild to severe subacute necrotizing myositis involving numerous skeletal muscles and most severe in the external ocular muscles and limbs. While many of these lesions have been seen in experimental infections of chickens with influenza viruses, the pattern of organs involved in this group of chickens is distinctive.

A 47-year-old white woman with a history of stage III squamous cell carcinoma of the anus was transferred to Johns Hopkins Hospital for further evaluation of renal failure, hemolytic anemia, and thrombocytopenia. The patient was first diagnosed with squamous cell carcinoma of the anus 1 year before admission. She was treated with external beam radiation of the pelvis and two cycles of mitomycin C-based chemotherapy (a cumulative dose, 34 mg/m(2)). Her clinical course was complicated by Clostridium difficile colitis and myositis successfully treated with prednisone. Three months before admission, the patient developed dysuria. Her creatinine increased from normal to 1.7 mg/dL, and microscopic hematuria was present. A renal ultrasound and an abdominal computed tomographic scan showed no abnormalities or obstruction. One month before admission, she underwent a cystoscopy, which showed only radiation-induced changes in the bladder. Two weeks before admission, the patient became delirious and was taken to a hospital, where she was found to be anemic, with a hematocrit level of 23.7%, and thrombocytopenic with a platelet count of 110,000/mm(3). Her creatinine level was 5.9 mg/dL. Previous values of hematocrit, platelet count, and serum creatinine were normal. On admission at Johns Hopkins Hospital the patient had no complaints. She was afebrile on physical examination and had normal vital signs. Head, neck, chest, cardiovascular, and abdominal examinations were normal. There was skin pallor, but no echymoses or petechiae. She was alert and oriented with normal mental status. Her neurologic examination was normal. Laboratory data showed a white blood cell count of 6390/mm(3), a hematocrit level of 26.5%, and a platelet count of 26,000/mm(3). Her blood urea nitrogen level was 57 mg/dL, creatinine level was 4.0 mg/dL, and lactate dehydrogenase was 550 U/L (reference, 115 to 275 U/L). Urinalysis showed innumerable red blood cells and large protein. A peripheral blood smear showed fragmented red blood cells, schistocytes, no abnormal white blood cells, and few platelets. There was no radiographic or clinical evidence of relapse of her squamous cell carcinoma. What is the diagnosis?

A captive-bred Bobwhite Quail ( Colinus virginianus) ranch in southern Utah, US experienced high mortality rates in the late summer and fall of 2012. Nine juvenile birds were necropsied at the Utah Veterinary Diagnostic Laboratory. Gross lesions included pale skeletal muscle with multifocal hemorrhages and petechiae in the air sacs and serosal surfaces of most organs. Histologically there was moderate to severe, multifocal, degenerative myositis with intramyofiber schizonts and minimal lymphoplasmacytic infiltrates in the proventriculus, ventriculus, heart, and skeletal muscle. There was also moderate fibrinoid to heterophilic vasculitis in multiple organs with vascular intraendothelial or intravascular merozoites and scattered thrombosis. In the liver and spleen there were multiple degenerative schizonts that had ruptured. Blood smears from three of the birds were stained with Wright-Giemsa stain and examined at a referral laboratory. Although the blood cells were deteriorated (postmortem artifact), life stages (exact stages not specified) consistent with Haemoproteus spp. were identified in erythrocytes. Polymerase chain reaction done on pooled tissues from two birds produced an amplicon in both pooled samples, and direct sequencing confirmed the presence of 533 base pairs of a Haemoproteus sp. in the subgenus Parahaemoproteus. The identification of Parahaemoproteus spp. in quail in southern Utah implies that appropriate Culicoides spp. vectors are present in the state and that there is potential risk to other birds such as zoo and aviary populations, wild turkeys, and other game birds.
