Hemophilus influenzae sepsis, rare in adults, is reported for the first time in association with multiple myeloma. The patient developed fulminant septicemia involving multiple organs and disabling pyarthrosis due to nonencapsulated H influenzae, usually considered to be nonpathogenic. Early diagnosis and appropriate antibiotic therapy cured the infection and prevented permanent joint disease. Also illustrated is the problem of establishing a diagnosis of myclomatosis in patients with septicemia. The English language literature on H influenzae sepsis and polyarthritis in association with myeloma has been reviewed.

Septicemia and meningoencephalitis developed in 10 pastured cattle 7 months to 3 years of age. Two unrelated herds were involved. Necropsy findings were similar to those previously reported in cattle infected with a Haemophilus-like organism, including multifocal intramuscular hemorrhages, suppurative polyarthritis, and multifocal hemorrhagic thrombi in the brain. A Haemophilus-like organism was isolated from one animal. It was characterized by growth on blood agar or tryptose agar plus a feeder streak under raised carbon dioxide tension, and lack of response to Haemophilus growth factors X and V.

Septicemia and meningoencephalitis developed in 10 pastured cattle 7 months to 3 years of age. Two unrelated herds were involved. Necropsy findings were similar to those previously reported in cattle infected with a Haemophilus-like organism, including multifocal hemorrhages in some muscles, suppurative polyarthritis, and multifocal hemorrhagic thrombi in the brain. A Haemophilus-like organism was isolated from one animal. It was characterized by growth on blood agar or tryptose agar plus a feeder streak under raised carbon dioxide tension, and lack of response to Haemophilus growth factors X and V.

Histophilus ovis was isolated from 29 sheep in 20 flocks and 2 artificial insemination (AI) centres in southern New South Wales from 1984 to 1990. The clinical and pathological findings were consistent with previous reports and included polyarthritis (7 flocks), epididymo-orchitis (5), meningoencephalitis (3), pneumonia (3), septicaemia (2), mastitis (1) and metritis (1). Six sheep had meningoencephalitis, a syndrome not previously associated with H ovis infection in sheep, which was similar pathologically to thromboembolic meningoencephalitis in cattle, caused by the related organism, Haemophilus somnus. H ovis was isolated from the semen of 12-month-old rams in a flock that had polyarthritis due to H ovis, in 4-month-old ram lambs and from the uterus of a ewe in a flock that had sporadic cases of H ovis septicaemia.

Three trials were conducted to establish if young primary specific pathogen free (SPF) pigs could be protected from Glasser's disease by vaccination. Three age groups of cesarean-derived isolator-reared gnotobiotic pigs were vaccinated twice at 4 and 6, 3 and 5, and 2 and 4 wk of age respectively with a formalin killed aluminum hydroxide adsorbed bacterin prepared from three strains of Haemophilus parasuis isolated from Ontario pigs affected with Glasser's disease. When challenged two weeks later with the homologous strains of virulent bacteria, all the vaccinated pigs remained healthy, while 17/18 nonvaccinated pigs became severely sick or died between three and seven days postchallenge. The one surviving nonimmunized pig was retarded in growth. All of the nonimmunized pigs had visible lesions of polyserositis, the most common being polyarthritis (14/18). Other lesions were fibrinous meningitis, pericarditis, pleurisy and/or peritonitis. Two of the pigs died with a septicemia. Haemophilus parasuis was isolated from 15/18 nonimmunized pigs, usually from several of the affected sites. The organisms were not isolated from the immunized pigs, nor from the surviving nonimmunized pig. Attempts to detect the presence of specific antibodies against the H. parasuis strains in the sera of the immunized or exposed pigs by the passive hemagglutination test or by enzyme linked immunoassay were unsuccessful. The results of this work indicate that primary SPF pigs can be protected from Glasser's disease by vaccination as early as 2 and 4 wk of age. The nature of this protective mechanism was not established in this study.

A 61-year-old man who presented with clinical features suggestive of septic arthritis was found to have acute septic polyarthritis due to Haemophilus influenzae (type b). The clinical and laboratory diagnoses of the case are presented, and the isolates of H. influenzae are characterized. Four isolates recovered from different sites had identical minimal inhibitory drug concentrations, outer membrane protein patterns, and genomic DNA restriction digests. These observations indicate that the disseminated infection arose from a single source. The patient developed antibody to several outer membrane proteins, particularly the P6 protein.

A 5-year-old girl with fever and tenderness in her left wrist and right ankle was hospitalized. Bone scanning and Tc-99m labeled leukocyte imaging showed increased uptake in these joints and also in her left knee. These radionuclide methods helped determine the diagnosis and were superior to plain radiography and CT scanning. Uptake was greater on leukocyte imaging than it was on the bone scan. The patient had infectious polyarthritis caused by Haemophilus influenzae, which is a very rare cause of acute polyarthritis in children older than 2 years. The patient fully recovered with antibiotic therapy, and no surgical procedure was needed.

Arthritic joints obtained from 50 freshly slaughtered pig carcasses condemned for polyarthritis were studied microbiologically. A routine technique was developed for aseptically opening joints to obtain material for microbiological examination. A standard series of culture media for the primary isolation of arthritogenic agents were used in the examination of each affected joint. The microbiological study cultured for isolation of the following microorganisms: Erysipelothrix rhusiopathiae, Corynebacterium pyogenes, Staphylococcus aureus, Escherichia coli, Streptococcus spp., Haemophilus spp., Mycoplasma spp., Salmonella spp., Chlamydia, and viruses.E. rhusiopathiae was found to be responsible for 48% of the cases of arthritis and Streptococcus spp., C. pyogenes and S. aureus for 20%, 4%, and 2% respectively; no microorganisms were cultured from 26% of the arthritic joints.

Haemophilus parasuis is a common cause of polyserositis and polyarthritis in swine. Little is known about the mucosal and systemic sites of replication and lesions which follow an aerosol exposure to H. parasuis. In this experiment 5-week-old cesarean-derived, colostrum-deprived (CDCD) pigs were inoculated intranasally with an inoculum containing 2 x 10(9) colony-forming units of H. parasuis. Two principals and one control pig were necropsied at 12, 36, 84, and 108 hours postinoculation (PI) and samples obtained for bacteriologic culture and microscopic examination. Inoculated pigs developed clinical signs of inappetence, reluctance to move, lameness, and a serous nasal discharge. Macroscopic findings included a fibrinous polyserositis and polyarthritis 36 hours PI which became progressively more severe at 84 and 108 hours PI. No lung lesions were grossly visible. Microscopic lesions included a mild purulent rhinitis at each post inoculation interval and fibrinous to fibrinopurulent synovitis and serositis at 36, 84, and 108 hours PI. A focal suppurative bronchopneumonia was observed in one pig examined at 36 hours PI. The nasal cavity and trachea were the only mucosal sites from which H. parasuis was reisolated. Haemophilus parasuis was isolated from the blood and systemic sites at 36, 84, and 108 hours PI. Findings presented indicated that intranasal inoculation of 5-week-old CDCD pigs with H. parasuis results in clinical signs and lesions of polyserositis and polyarthritis typical of field cases and is a useful model for the study of H. parasuis pathogenesis. The results also suggest that H. parasuis initially colonizes the nasal mucosa.

Chronic, antibiotic-resistant pneumonia, sometimes with concurrent polyarthritis, occurs in feedlot cattle in western Canada. The prevalence of Mycoplasma bovis, bovine viral diarrhea virus, and Haemophilus somnus was determined by using immunohistochemical staining of lung and heart tissue from 2 groups of animals with this history. Mycoplasma bovis antigen was present in 44/48 cases submitted between 1995 and 1998 (retrospective group) and 15/16 of cases from 1999 (prospective group), and was associated with pulmonary necrosis. Bovine viral diarrhea virus antigen was present in association with microscopic vascular lesions in 31/48 retrospective and 9/16 of prospective cases. Types Ib and II bovine viral diarrhea virus were isolated from 4/16 prospective cases. Haemophilus somnus antigen was present in heart, lung, or both of 15/48 retrospective and 8/16 prospective cases. The results suggest that there may be synergism between bovine viral diarrhea virus and M. bovis in this pneumonia with arthritis syndrome.
