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.

Seventy episodes of Staphylococcus aureus sepsis occurring over a nine-year period in pediatric cancer patients are reviewed. Prominent findings at the time of diagnosis included fever, granulocytopenia, and active malignancy. Probable or suspected sites of primary infection were present in 40 episodes (57%). Serious direct complications of staphylococcal sepsis included only three cases of pneumonia and one of myositis. However, second infections by other organisms developed in 16 episodes (24%), resulting in nine nonstaphylococcal infectious deaths during therapy. Endocarditis and osteomyelitis never occurred in this group of patients. The median duration of antistaphylococcal therapy was 15 days.

The Wisconsin Division of Health (DOH) began surveillance for severe illnesses associated with group A beta-hemolytic streptococcus (GABS) infections in late 1989 to describe the current epidemiologic features and clinical spectrum of these infections in the state. Severe illness was defined by the isolation of GABS from the blood or by the development of one or more of the following in a patient infected with GABS: shock, extensive tissue injury, desquamating rash, disseminated intravascular coagulation, renal failure, adult respiratory distress syndrome, or death. Case reports involving 28 patients with severe GABS-related illnesses with onset from November 1989 through October 1990 were received by the DOH. The majority of the case-patients had sepsis (57%), cellulitis (50%) or both. Nine (32%) cases were fatal. Those who died were older than those who survived (median age 74 years v 43 years, p = 0.002) and were more likely to have clinical diagnoses that included pneumonia (relative risk [RR] 3.0, 95% confidence interval [CI] 1.2, 7.3) or necrotizing fasciitis/myositis (RR 3.7, 95% CI 1.5, 9.0). The median interval from illness onset to hospitalization was similar for fatal cases (1 day) and non-fatal cases (2 days), suggesting that early intervention after the appearance of clinical illness may not improve the outcome.

Six cats (Nos. 1-6) were inoculated intramuscularly with (1 x 10(6)) and orally (5 x 10(5)) tachyzoites of Neospora caninum. Three (Nos. 1-3) of the six cats were given 40 mg/kg methylprednisolone acetate 7 days before and on the day of inoculation with N. caninum tachyzoites, and three cats (Nos. 4-6) were not given methylprednisolone acetate. Two of the cats (cat Nos. 1 and 2) given methylprednisolone acetate died suddenly. Cat No. 1 died 8 days post-inoculation, and cat No. 2 died 16 days post-inoculation. Cat No. 3 was euthanatized 21 days post-inoculation. Cat No. 1 had lesions of gram-positive bacterial septicemia. Necrotizing encephalitis, myelitis, disseminated skeletal muscle necrosis, hepatic necrosis, interstitial pneumonia, and renal tubular necrosis were the main lesions in cat Nos. 2 and 3. The cats that were not given methylprednisolone acetate remained clinically normal except for slight weight loss in cat No. 6. All three of these cats were euthanatized 55 days post-inoculation. Mild myositis and encephalitis were noted on microscopic examination of tissues from these three cats. Neuromuscular lesions were not seen in six control cats (Nos. 7-12) not inoculated with N. caninum and euthanatized 21 or 22 days after administration of the first two doses of methylprednisolone acetate (40 mg/kg), given at a weekly interval.

Two cases of Fusarium infection in patients with refractory hematologic malignancies are reported. In one patient septicemia progressed to death in septic shock. Miconazole showed some effect in clearing the lesions. There is some evidence that mycotoxins are related with Fusarium infections since severe myositis occurred in our patient. The other patient had a T-cell lymphoma, undergoing allogeneic bone marrow transplantation. The course was also complicated by Fusarium infection of the skin. This patient died of multiorgan failure. Recent literature on Fusarium is reviewed.

Although the first Aeromonas strain was described by Zimmermann as early as in 1890, it took 60 years until Caselitz established human pathogenicity of strains then called "Vibrio jamaicensis". Since then, and especially in the last 10 years, there have been increasing numbers of reports on different infections caused by members of the genus Aeromonas. These include sepsis; meningitis; cellulitis; necrotizing fasciitis; ecthyma gangrenosum; pneumonia; peritonitis; conjunctivitis; corneal ulcer; endophthalmitis; osteomyelitis; suppurative arthritis; myositis; subphrenic abscess; liver abscess; cholecystitis and/or ascending cholangitis; urinary tract infection; endocarditis; ear, nose, and throat infections; balanitis; etc. The role of Aeromonas in gastrointestinal disease is very controversial. Increasing epidemiological data suggest that these organisms play a major role in enteric infections, but so far enteropathogenicity has not been demonstrable in experiments where volunteers were given high numbers of Aeromonas possessing different virulence factors. Virulence factors include hemolysin(s), enterotoxin(s), hemagglutinins, invasivity, and others; but these are not found more frequently in strains isolated from patients with diarrhea than from healthy controls. Whether there is a correlation between species and disease remains to be elucidated and requires more information about the taxonomy of this genus.

A 54-year-old man presented with gangrenous myositis caused by Streptococcus pyogenes. A review of the literature disclosed 10 similar cases. Their presenting manifestations were spontaneously occurring, localized, excruciating pain; mottling suggestive of ischemic changes; and signs of sepsis. The duration of illness ranged from two to six days, and the outcome was uniformly fatal. This rare but distinct entity resembles clostridial myonecrosis except that it lasts slightly longer and does not involve gaseous crepitus. A definitive diagnosis of myonecrosi scan be established by surgical exploration; early, radical debridement plus penicillin therapy should be undertaken after diagnosis in an attempt to alter the usual devastating outcome.

Six horses had been admitted to the hospital because of illness other than renal failure; diarrhoea, myositis, abdominal pain and/or suspected bacterial sepsis. Hypotension and disseminated intravascular coagulopathy were frequent findings in the horses. Abnormally high serum creatinine concentration and urine specific gravity of less than 1.022 were found in the horses with acute renal failure. Hyponatraemia and hypochloraemia were the most common abnormal electrolyte findings. Pronounced hyperkalaemia was not found. Variable degrees of tubular necrosis were seen in three of the four horses that had kidney sections submitted for microscopic examination. Renal cortical necrosis occurred in one horse. Intravenous fluid and electrolyte replacement was the most important therapy in those cases that were non-oliguric. Furosemide, mannitol and dopamine were used in horses with oliguria. The prognosis was generally good if the predisposing cause could be corrected and the acute renal failure was not oliguric.

V vulnificus is a halophilic or salt-requiring vibrio that has been isolated repeatedly from seawater and shellfish in coastal waters. This vibrio, first described by Hollis et al in 1976, can be differentiated from other similar vibrios by its ability to ferment lactose and by its lower tolerance for sodium chloride. V vulnificus, unlike most other vibrios, has seldom been incriminated as a cause of gastroenteritis but is a particularly virulent organism that causes severe wound infections in mostly healthy persons, or causes primary septicemia in persons with an underlying chronic disease, particularly chronic liver disease. Wound infections may range from relatively mild to severe and rapidly progressive cellulitis and myositis. Approximately 50% of patients with wound infections have some type of chronic underlying disease and the mortality rate is in the range of 15%. Wound infections are almost always associated with contact with seawater or the handling or cleaning of shellfish. Patients with primary septicemia have fever, chills, and prostration, and rapidly become hypotensive. Over 70% have distinctive bullous skin lesions that can strongly suggest the diagnosis in a patient with the appropriate history. The mortality rate is over 50%. There is a striking association between eating raw oysters and primary septicemia, with patients usually reporting having eaten raw oysters (or other shellfish) 24 to 48 hours before onset of symptoms.(ABSTRACT TRUNCATED AT 250 WORDS)

Pasteurellosis was diagnosed in a red-fronted conure (Aratinga wagleri) that had been bitten on its breast by a cat 2 weeks before death. The wound spread rapidly, involving the skin over the entire breast and the underlying musculature. Septicemia that followed dermatitis and myositis was the cause of death. Pasteurella multocida was isolated in pure culture from the heart blood and liver. Diagnosis of Escherichia coli septicemia and enteritis in a hyacinth macaw (Anodorhynchus hyacinthinus) was based on lesions such as generalized hyperemia and hemorrhages in visceral organs, fibrinonecrotic lesions in the intestine, and isolation of E coli in pure culture from the heart blood, liver, and intestine.
