Porcine arthritis and meat hygiene in South Africa.

The incidence, economic implications, aetiology and possible public health significance or porcine arthritis in South African slaughter pigs is discussed. An investigation into the aetiology and pathology of porcine arthritis as found at a South African abbattoir revealed that Erysipelothrix rhusiopathiae was present in 48% of the affected joints and Streptococcus spp., Corynebacterium spp. and Staphylococcus spp. in 20%, 4% and 2% respectively. The joints showed various degress of subacute to chronic proliferative sero-fibrinous to fibrinopurulent arthritis regardless of whether bacteria were isolated. It is essential that the Lnn. axillares primae costae which drain the forelimb joints also be examined routinely during meat inspection.

[Resorption of colostral gamma-globulins and detection of antibodies to Bact. rhusiopathiaesuis, S. cholerasuis and beta-hemolytic Esch. coli in newborn pigs].

Traced was the resorption of colostral globulins and the production of antibodies against Bacterium rhusiopathiae suis, S. choleraesuis, and beta-hemolytic Escherichia coli organisms in newborn pigs. It was found that in the newborn pigs that had not yet started sucking there were no gamma-globulins and specific antibodies against the agents mentioned above. Such were observed after the animals had begun to suck, the titers of antibodies reaching their peak levels by the 10th--15th hour (erysipelothrix and paratyphoid) and the 24th--48th hour (hemolytic Escherichia coli). As against their mothers the titer of the antibodies in the sucklings was two to four times as lower. The gamma-lactoglobulins are resorbed along the whole intestinal mucous membrane, however, resorption is most intense in the duodenum and the jejunum in the course of the first 2 days after farrowing; from the fifth day on it ceases.

Erysipelas in quail and suspected erysipeloid in processing plant employees.

Erysipelas was diagnosed in two commercial breeder flocks of Coturnix quail and was characterized clinically by sudden mortality. At necropsy, lesions comprised generalized congestion, hemorrhages in the thigh and breast muscles, swelling of liver, spleen, and kidney, and dark red edematous lungs. Erysipelothrix rhusiopathiae was cultured from visceral organs of affected birds. Medication with penicillin in the drinking water controlled the mortality. A possible source of infection was fish raised on the premises. Seven people at the quail processing plant developed localized inflammation of the fingers, which responded when antibiotic therapy for erysipeloid was initiated.

[The development of a technology for the production of live dried vaccines against avian pasteurellosis and swine erysipelas].

The technology of the production of dried live vaccine against Pasteurella infection of fowl from Pasteur's 2nd avirulent strain, strains AB and K, has been developed. This technology includes the process of batch cultivation of Pasteurella cells, controlled in such parameters as eH, pO2 and glucose concentration, in fermenters in optimized culture medium, based on Hottinger hydrolysate and fermentative casein-yeast hydrolysate, and preservation in improved saccharose-gelatin medium prepared in potassium sulfate buffer solution. The new technology makes it possible to increase the yield of preparations with stable biological activity 5- to 13-fold in comparison with the traditional technology. Furthermore, the technology of the production of live dried vaccine against swine erysipelas from Erysipelothrix insidiosa strain BP-2 has been developed. This technology is based on maintaining the optimum conditions of the batch cultivation of E. insidiosa in meat medium based on Hottinger hydrolysate and media obtained from hydrolysate of pancreatic fermentation products of microbial biomass; the preparation thus obtained is stabilized in peptone-saccharose-gelatin medium prepared in potassium phosphate buffer solution. This increases the yield of the vaccine 8-fold in comparison with the traditional technology, while ensuring the stability of bacteria after drying and during prolonged storage.

Erysipelas in a black and red tamarin.

Erysipelothrix rhusiopathiae was isolated in large numbers from the kidneys and was visualized histologically in the kidneys, heart muscle, skeletal muscle, selected lymph nodes, and the submandibular salivary glands of a black and red tamarin (Saguinus nigricollis) following an acute fatal illness. Sites (heart valves, joints) usually associated with disease mediated by E rhusiopathiae appeared uninvolved.

Erysipelas arthritis in swine: lysosomal enzyme levels in synovial fluids.

Arthritic and histologically normal joints from swine in which arthritis had been produced by the intravenous inoculation of Erysipelothrix rhusiopathiae were used as a source of fluids for lysosomal enzyme determinations. Mean lysozyme activities in synovias from arthritic and histologically normal joints were 16.60 and 5.79 mug/ml, respectively. Acid phosphatase (ACP) was increased more than 8 times the activity in histologically normal joints, but there was no relationship between lysozyme and ACP, indicating the probability that 1 of these enzymes came from another source. The cytoplasmic enzyme, lactic dehydrogenase (LDH), was increased in proportion to ACP, indicating that cell death and not selective extrusion of lysosomal enzymes during phagocytosis was an important mechanism of enzyme release in arthritic joints. Lysozyme activities in synovias from histologically normal joints were often increased above companion serum concentrations, indicating the enzyme has a special role in the joint. Also, the ratio of activities of lysozyme to ACP in pig buffy coat lysates was different from the ratio of the 2 enzymes in synovias from arthritic joints.

Acute nonfatal erysipelas in sows in a commercial farrow-to-finish operation.

Acute nonfatal erysipelas was diagnosed in 4 sows in a 1,000-sow commercial farrow-to-finish operation in Indiana. Sows were pyrexic, lethargic, lame, and had multiple, 1.3- to 7.6-cm, erythematous rhomboid skin lesions. Outbreak was attributed to failure to properly vaccinate pigs. Further morbidity and mortality were prevented by treatment of clinically affected sows and all pigs in close proximity with procaine penicillin G daily for 3 consecutive days and vaccination of all pigs with questionable vaccination status, using bacterin of killed Erysipelothrix rhusiopathiae. Periodic review of herd management protocols is important to ensure that recommended vaccination schedules are being followed and animals are receiving quality vaccinations. Human error can contribute to many production problems and should be included on the differential diagnoses list.

Arthritis in the prehistoric Southeastern United States: biological and cultural variables.

Recent research shows that a bacterial life form, Erysipelothrix insidiosa, can produce rheumatoid arthritis in deer, swine, and dogs, and that a number of animals, including man, birds, and fish, may be infected by the organism. Examination of the archaeological record suggests that both cultural and biological variables may be interrelated in the maintenance of some forms of arthritis over long periods of time in geographically disparate populations. Re-examination of Cherokee folk beliefs concerning arthritis suggests that they had some recognition of this connection, and it also suggests that they had some recognition of this connection, and it also suggests that the term "magical" may relate more to the world view of the observer than to any actual inability of preliterate peoples to draw causal relations on the basis of their own intimate knowledge of their environments.

A convenient gel holder for preparative electrophoretic separation of aggregated bacterial proteins.

A simple custom-made gel holder for preparative SDS-PAGE to separate aggregated bacterial antigens is described. The gel holder fits easily into commercially available gel electrophoresis apparatus and proteins or peptides are collected in a stream of distilled water through a channel in the gel. The performance of the device was illustrated by the successful separation and purification of fragments of aggregated Streptococcus equi M protein and of Erysipelothrix rhusiopathiae protective antigens. Yields of up to 1.2 mg per run were obtained. The purified proteins retained immunological reactivity and were of sufficient purity for amino acid compositional and sequence analysis.

Treatment of surgical infections with a modern quinolone: therapy of soft tissue infections and pneumonia with ofloxacin.

A randomized, open, prospective study including 45 patients with either soft tissue infections (29 cases) or pneumonia (15 cases) after surgical intervention and one case having both indications was carried out with ofloxacin. The standard dose was 200 mg ofloxacin b. i. d. In most cases, clinical symptoms, such as fever, rubor, swelling and pain in soft tissue infections, as well as fever, dyspnoea, physical and radiological signs for pneumonia, subsided within two to seven days. Laboratory data (blood analyses, liver enzymes) remained in the normal range. The overall tolerability was good. Bacteriological controls have proven that ofloxacin is able to eradicate a broad range of pathogens, including persister pathogens and also certain bacteria like Clostridium perfringens and Erysipelothrix rhusiopathiae. In our study, Streptococcus faecalis was of intermediate sensitivity in one case and resistant in another. Ofloxacin has proven to be effective in soft tissue infections and pneumonia after surgical intervention.

Home intravenous antibiotic therapy for patients with infective endocarditis.

Although home intravenous antibiotic therapy (HIAT) is increasingly being used for various infectious diseases, outpatient treatment of infective endocarditis (IE) is still uncommon. Recently, the American Heart Association recommended outpatient treatment of endocarditis only for infections with streptococci that are highly susceptible to penicillin. Herein, the experience with HIAT in patients with IE due to a diversity of pathogens is presented. During a 3-year period, 37 patients with IE who were in a stable condition and were cooperative were enrolled in a service for HIAT after completion of diagnostic procedures. Of the 37 patients, 21 were male; mean age was 64.3 years (range 20-87 years); in most cases (26/37), IE involved a native valve. Causative organisms were Streptococcus spp. (20), Staphylococcus spp. (10), Enterococcus spp. (2), Enterobacter spp. (1), and Erysipelothrix rhusiopathiae (1), while three were unknown. The most common antibiotics used were ceftriaxone and vancomycin. Almost three-quarters of the intravenous lines were peripheral. The mean duration of HIAT was 26.2 +/- 8.5 days, with 92% of the patients cured by it. Most complications were minor. Six patients were rehospitalised and two of them required valve replacement. In half of the rehospitalised patients, the complication was unrelated to HIAT. Surprisingly, almost all of the complications necessitating rehospitalisation occurred in patients with streptococcal IE and most involved native valves. HIAT may be suitable for IE due to a diversity of pathogens and involving prosthetic as well as native heart valves, provided there are proper patient and antibiotic selections, good follow-up, and vigilant monitoring of complications.

Comparison of a commercial disk test with vancomycin and colimycin susceptibility testing for identification of bacteria with abnormal gram staining reactions.

In an effort to identify bacteria that fail to give the expected Gram reaction, thus leading to misidentification, two nonstaining tests for Gram reaction, vancomycin and colimycin susceptibility testing and the Gram-Sure test (Remel, USA), were employed on 145 strains from 42 gram-negative and gram-positive genera with contradictory Gram stain results. The Gram-Sure test is a commercially available disk that detects the presence of L-alanine-aminopeptidase, an enzyme usually found only in the cell wall of gram-negative bacteria. In this test, aminopeptidase activity is detected using a substrate that can be hydrolyzed to produce a fluorescent compound under long-wave UV light. The commercial disk test and vancomycin plus colimycin susceptibility testing appeared to perform equally well except in the identification of Erysipelothrix and Lactobacillus, for which the commercial disk test was better, and Moraxella, for which vancomycin and colimycin susceptibility testing was more helpful. An advantage of the commercial disk test is that it can be performed in 10 min, whereas vancomycin and colimycin susceptibility testing requires at least 18 h. The commercial disk test is also less expensive than vancomycin and colimycin susceptibility testing. However, since the same results can be obtained with the 5 microg and 30 microg vancomycin disks, it is possible to use only one vancomycin disk, with the cost then being equivalent to that of the commercial disk test. The major inconvenience of the commercial disk test is the requirement of a UV ray. However, this test could be a useful tool for the identification of unusual organisms.

In vitro activity of daptomycin against clinical isolates of Gram-positive bacteria.

We determined the activity of daptomycin, a recently FDA-approved antimicrobial agent, against clinical isolates of Gram-positive bacteria, including viridans group streptococci (16 Streptococcus mitis species group, 12 S. mutans species group, 9 S. anginosus species group, 8 S. sanguinis species group, 5 S. salivarius species group) from patients with infective endocarditis, 32 methicillin-resistant Staphylococcus aureus, 32 high-level penicillin-resistant Streptococcus pneumoniae, 38 vancomycin-resistant enterococci (including 1 linezolid-resistant isolate), and the following unusual Gram-positive bacteria: 3 Listeria monocytogenes, 4 Erysipelothrix rhusiopathiae, 9 Corynebacterium species, 10 Abiotrophia/Granulicatella species, 2 Rothia (Stomatococcus) mucilaginosus, and 4 Gemella morbillorum. Daptomycin minimum inhibitory concentration (MIC)(90) values for the viridans group streptococci, methicillin-resistant S. aureus, penicillin-resistant S. pneumoniae, and Enterococcus species were 0.5, 0.5, < or =0.125, and 4 microg/ml, respectively. The daptomycin MIC range for the unusual Gram-positive bacteria was < or =0.125-2 microg/ml. We conclude that daptomycin has in vitro activity against viridans group streptococci associated with endocarditis as well as against several types of unusual Gram-positive bacteria that can cause endocarditis.

Use of low molecular mass RNA profiles to identify lactic acid bacteria and related organisms associated with foods.

Fourteen strains of lactic acid bacteria and species of Brochothrix, Carnobacterium, Enterococcus, Erysipelothrix, Kurthia and Listeria were examined using low molecular mass RNA (5S rRNA and tRNA) profiles. These profiles were developed on denaturing polyacrylamide gels. Gel strengths between 9 and 14% were tested to improve resolution of distinct bands for densitometrical analysis. Profiles generated on 12% gels proved to be the best for scanning. Scans of class 2 tRNAs by densitometry showed a characteristic profile for each genus. In the case of Lactobacillus each species studied gave a unique profile. The technique of low molecular mass RNA profiling may provide a useful means for identifying different bacteria from ecosystems such as meats.

Antimicrobial activity of cefotaxime tested against infrequently isolated pathogenic species (unusual pathogens).

The cefotaxime sodium spectrum of activity is very broad and includes many common species and a variety of less frequently isolated pathogens. We have reviewed the clinical microbiology literature (44 references) and the data base of the University of Iowa Hospitals and Clinics (Iowa City, IA) to collect data on the activity of cefotaxime against the less common species. Cefotaxime was consistently active against Actinobacillus actinomycetemcomitans, Capnocytophaga spp., Eikenella corrodens, Erysipelothrix rhusiopathiae, Pasteurella multocida, Plesiomonas shigelloides, and Fusobacterium nucleatum. The species Alcaligenes xylosoxidans, Flavobacterium spp., Stenotrophomonas (Xanthomonas) maltophilia, Bacillus cereus, Listeria monocytogenes, and Rhodococcus equi were uniformly cefotaxime resistant. For many other species there was considerable variation in reported minimum inhibitory concentrations. These data may be helpful in guiding therapy of unusual infections, particularly in the case of fastidious species, where the appropriate susceptibility testing methodology may not be immediately or routinely available.

Bacterial flora of free-living double-crested cormorant (Phalacrocorax auritus) chicks on Prince Edward Island, Canada, with reference to enteric bacteria and antibiotic resistance.

Cloacal and pharyngeal swabs from 100 tree-nesting Double-crested cormorant (DCC) chicks were examined by culture for commensal and potentially pathogenic bacteria. No Salmonella or Erysipelothrix were isolated from the cloacal swabs. Twenty-two cloacal swabs were positive for Campylobacter, of which 14 were C. jejuni, C. coli, and 1 C. lari. None belonged to common serotypes isolated from humans or animals in recent years in Canada. Tests for antimicrobial drug resistance among 187 commensal Escherichia coli isolates from the cloacal swabs indicated that < or =5% were resistant to any of the 12 antibiotics tested. This contrasts with the frequently high resistance rates among E. coli isolates from poultry. Pharyngeal swabs from DCC were negative for Pasteurella multocida. Culture of cloacal swabs from 100 ground-nesting DCC chicks resulted in the recovery of 19 Salmonella isolates, all of which were S. enterica serotype Typhimurium. None of these isolates were resistant to any of the 12 antibiotics tested. Altogether, these findings suggest that DCC from this region are not being colonized with commensal or potentially pathogenic enteric bacteria from agricultural or human sources and that enteric bacteria isolated from these birds are unlikely to contribute to a gene pool of antimicrobial drug resistance.

Efficacy of oral vaccination against swine erysipelas in growing-finishing pigs in a clinically infected Slovakian pig herd.

In a large Slovakian growing-finishing pig production unit, the effects of oral vaccination against swine erysipelas (SE) were investigated in three groups of pigs of 10 weeks of age. In group 1, the pigs were vaccinated intramuscularly at 1 and 3 weeks after arrival in the growing-finishing barn using an Erysipelothrix rhusiopathiae bacterin. Group 2 pigs were vaccinated at the same time as group 1 using an oral avirulent live SE vaccine administered through drinking water; the pigs in the third group were placebo treated. Clinical signs of acute SE, arthritic changes, average daily weight gain (ADG), feed conversion ratio, and mortality were evaluated. None of the pigs in groups 1 and 2 but 31.7% of the control animals (group 3) showed typical clinical signs of acute SE. More (P<0.01) non-vaccinated pigs had chronic arthritic changes compared with groups 1 and 2. No significant differences in mortality were recorded between the groups. Groups 1 and 2 had higher (P<0.05) ADG and lower feed conversion ratios compared with group 3 pigs. The results demonstrated that the oral avirulent live culture was efficacious in significantly reducing the clinical symptoms caused by E. rhusiopathiae infection, so enhancing the pigs' performance.

Concurrent swine erysipelas and Clostridium novyi infections associated with sow mortality in outdoor sows in Kenya.

A sudden increase in sow mortality was reported from a large outdoor pig-breeding unit in Kenya. The sows showed pyrexia and diamond shaped to confluent skin lesions ante-mortem. Gross pathological examination of the carcases was performed and organ samples (heart, liver, kidney, spleen, mandible lymph nodes) were sent for further diagnostic investigation. Based upon the clinical, gross- and microscopic-pathological signs, bacteriological findings and toxin testing, concurrent infection with Erysipelothrix rhusiopathiae and Clostridium novyi was diagnosed as the cause of the sow mortality.
