Salmonella enterica subspecies enterica serotype Dublin (S. enterica Dublin) emerged for the first time in New York, Pennsylvania, and Ohio in 1988. Since that time this host-adapted serotype has spread throughout the veal- and dairy beef-raising operations in the region; very few dairy farms have experienced clinical S. enterica Dublin infections. This study details the epidemiology of the outbreaks in cattle. During the period 1988 through 1995, nine New York and four Pennsylvania counties have been affected; 13 different locations were involved in New York, and 10 were involved in Pennsylvania. The morbidity and mortality and seasonal distribution of outbreaks, which totaled 35, is described. The antimicrobial susceptibility pattern of isolates revealed that many of the strains were resistant to a number of commonly used drugs. Clinical case details and pathology information are provided, with a caution to clinicians and microbiologists presented with suspect animals, i.e., most cases occurred in older calves, which is atypical for salmonellosis for this region (calves were 8 or more weeks old) and presented as pneumonia and septicemia rather than the primarily diarrheal syndrome that is more typically recognized for the region. The epidemiology of cases is analyzed through cluster analysis of bacterial isolates and their fatty acid methyl ester profiles; at least six clones appeared in the region during the study period. Results of the epidemiology analysis are used to support a hypothesis regarding the source of S. enterica Dublin for the region and its manner of dissemination.

Bone infections are usually due to haematogenous spread from distant infected organs. Spread of local sepsis or contamination of open wounds are less frequent routes of infection. The commonest cause of osteomyelitis is Staphylococcus aureus. The term rare bone infections refers to diseases where only a few percent affect bone or diseases which are essentially rare; these include bacteria, fungi, parasites and non-specific conditions. Common examples are tuberculosis, salmonellosis, brucellosis, hydatidosis, madura, actinomycosis, aspergillosis and American fungal infections. Certain bone infections have become exceedingly rare, particularly atypical mycobacteria, viral embryopathies and spirochaetes. Rare bone infections are encountered in many parts of the world commonly in the tropics and in the U. S. Immunocompromise and ease of travel can lead to increased incidence. A high index of clinical suspicion is necessary for diagnosis. Specific laboratory diagnosis is not always possible. Radiographs, computed tomography, isotope studies and magnetic resonance are useful but may not make the diagnosis. Aspiration or biopsy is necessary. Rare bone infections may simulate non-infective bone lesions.

A previously healthy 15-year-old female was admitted to our hospital complaining of nausea and vomiting. She did not complain of diarrhea. A physical examination revealed a lower right quadrant abdominal tenderness without rebound or spontaneous pain and a knocking pain of the costovertebral angle. A high fever, knocking pain of costovertebral angle, and urinary findings including Gram's stain, lead us to suspect a urinary tract infection, cefotiam was administered intravenously. Spiking fever with shaking chills continued for three days, and three sets of blood cultures were positive for Salmonella Oranienburg, but her urine culture was negative. Her history was taken again, revealing an intake of a processed squid product. The product was confirmed by the local public health center to be Salmonella Oranienburg. Finally food poisoning by Salmonella Oranienburg with sepsis was diagnosed. With cefotiam she became better and was discharged from the hospital on the 10th hospital day. During admission to the hospital she did not experience any diarrhea, and her stool culture was negative. Epidemics of Salmonella Oranienburg food poisoning are relatively rare in the literature. In Japan, one has arisen as a result of contamination of a processed squid product in March 1999. However, there have been no cases without so-called gastroenteritic symptoms (abdominal pain and diarrhea) who were previously healthy and developed sepsis caused by Salmonella Oranienburg, reported in Japan. Even in previously healthy patients, with an epidemic situation of non-typhoidal salmonellosis, salmonella sepsis must be ruled out. Among such cases, those who present with spiking fever and shaking chills should be given antibiotic therapy after taking appropriate cultures.

During 1996-1998, CDC received reports from approximately 16 state health departments of Salmonella infections in persons who had direct or indirect contact with reptiles (i.e., lizards, snakes, or turtles). Salmonella infection can result in invasive illness including sepsis and meningitis, particularly in infants. Despite educational efforts, some reptile owners remain unaware that reptiles place them and their children at risk for salmonellosis. This report summarizes clinical and epidemiologic information in four cases and provides information about state regulations to prevent transmission of Salmonella spp. from reptiles to humans.

Norepinephrine stimulates growth of Escherichia coli, Yersinia enterocolitica, and Pseudomonas aeruginosa in serum-supplemented media, and in vivo increases in norepinephrine may be important in the pathogenesis of sepsis by gram-negative bacteria. Because salmonellosis often is associated with stress, the effects of norepinephrine on in vitro growth, and in vivo pathogenicity of the swine pathogen Salmonella choleraesuis were investigated. When RPMI 1640 with and without pig serum was inoculated with fewer than 100 S. choleraesuis/ml and incubated overnight, bacterial numbers were 10(4) to 10(6) lower in RPMI containing serum. Norepinephrine restored bacterial growth in RPMI with serum to normal levels, but it did not increase growth in serum-free RPMI. Similar results were obtained with SAPI, a nutrient-poor medium previously used to study the effect of norepinephrine on growth of gram-negative bacteria. Conditioned media were produced by growing S. choleraesuis in RPMI containing serum with and without norepinephrine and filter sterilizing. Conditioned medium produced with norepinephrine stimulated growth of S. choleraesuis but not E. coli, whereas conditioned medium produced without norepinephrine stimulated growth of both bacteria. To determine the in vivo effects of norepinephrine, rats were implanted with tablets that secrete norepinephrine for 20 to 24 hours or with identical tablets without norepinephrine and infected intraperitoneally with graded doses of S. choleraesuis. The LD-50 of S. choleraesuis was the same in both groups, and norepinephrine did not affect the carrier rate at 30 days after infection. We concluded that although norepinephrine stimulates in vitro growth of S. choleraesuis in serum-based media, the increase in norepinephrine levels in the present in vivo system was probably not sufficient to influence the pathogenesis of S. choleraesuis infection.

Infection is a major complication and the leading cause of death in thalassemia, especially E-beta thalassemia. The spectrum of infections in E-beta thalassemia include mild and severe infections, therapy-related infections such as Yersinia enterocolitica infection associated with desferrioxamine (DFO) therapy, and transfusion-transmitted disease, as well as unique infections such as with pythiosis. Prospective studies in Thailand indicate that patients with E-beta thalassemia had more frequent episodes of both mild and severe infections. The former included upper respiratory tract infection, acute gastroenteritis, cutaneous abscess, and gingivitis. Severe infections occurred more commonly in patients with splenectomy and included septicemia, pneumonia, biliary tract infection, salmonellosis, and urinary tract infection. Responsible organisms were Escherichia coli (26%), Klebsiella pneumoniae (23%), Salmonella (15%), and Streptococcus pneumoniae (13%). Other organisms included Pseudomonas, Staphylococci, Burkholderia pseudomallei (melioidosis), and Aeromonas. Patients undergoing DFO therapy are at risk for Y. enterocolitica infection which may be localized to mesenteric nodes and tonsils or occur as a generalized form such as septicemia. Recently, we have seen a unique infection so-called vascular pythiosis. Patients usually presented with clinical features of vascular occlusion of lower limbs from ascending arteritis and thrombosis. The causative organism, Pythium insidiosum, is fungus-like, in the kingdom Stramenopila, and in the class Oomycetes. The mortality rate is high and the only effective treatment has been early amputation or possibly immunotherapy. The predisposing factors of infections in thalassemia include splenectomy, iron overload, anemia, and granulocyte dysfunctions. General management of infections in thalassemia consist of prevention, i.e., immunization with pneumococcal and hepatitis vaccines, oral penicillins especially in patients with splenectomy, removal of predisposing factors such as gallstones, iron overload, and appropriate antibiotics.

The objective of this study was to characterize the clinical profile of lupus patients with non-typhoidal salmonellosis. A retrospective review of the clinical charts of lupus patients diagnosed with bacteriologically proven non-typhoidal salmonellosis over the last 20 y was undertaken, paying special attention to risk factors, clinical presentation and treatment outcome. Most episodes were bacteraemic without a localizing focus; and some patients were afebrile. They usually occurred in patients prone to opportunistic infections, and at times of increased immunosuppression given for lupus flares (especially nephritis). However, salmonellosis also occurred in some patients presenting with lupus. The C-reactive protein level was found to be significantly higher during the infective episodes compared to episodes of non-infective febrile lupus flare. All isolates were sensitive to the usual first-line antibiotics and eminently treatable with 3 weeks of appropriate antibiotics without recurrence/persistence or significant morbidity/mortality, the exceptions being spinal osteomyelitis and septic arthritis involving deformed joints requiring surgical debridement and prolonged antibiotic therapy for eradication. Mortality occurred in the setting of septic shock from mixed-microbial sepsis and major organ failure from active lupus. There is a high association of non-epidemic, non-typhoidal salmonellosis with SLE, especially in patients with active disease on intensified immunosuppression. The C-reactive protein value may be helpful in distinguishing between fever from a pure lupus flare and one complicated by infection.

Abscess formation by Salmonella species is an uncommon but significant manifestation of salmonellosis, because this type of infection has high morbidity and mortality rates and is a potential nosocomial hazard. In infants, history of consumption of contaminated water should be especially quired. We report a case who had sepsis and multiple brain abscesses due to Salmonella paratyphi B and who responded to sulbactam-ampicillin (SAM) therapy. Sulbactam-ampicillin combination may be preferable due to its immunomodulator effect.

Between May 1996 and February 1997, 27 horses and a veterinary student at a veterinary teaching hospital developed apparent nosocomial Salmonella Typhimurium infection. The source of the multiple-drug resistant Salmonella Typhimurium was a neonatal foal admitted for treatment of septicemia. A high infection rate (approx 13% of hospitalized horses) coupled with a high case fatality rate (44%) for the initial 18 horses affected led to a decision to close the hospital for extensive cleaning and disinfection. Despite this effort and modification of hospital policies for infection control, 9 additional horses developed nosocomial Salmonella Typhimurium infection during the 6 months after the hospital reopened. Polymerase chain reaction testing of environmental samples was useful in identifying a potential reservoir of the organism in drains in the isolation facility. Coupled with clinical data, comparison of antimicrobial resistance patterns of Salmonella Typhimurium isolates provided a rapid initial means to support or refute nosocomial infection. Although minor changes in the genome of these isolates developed over the course of the outbreak, pulsed-field gel electrophoresis testing further supported that salmonellosis was nosocomial in all 27 horses.

Salmonella infection of a hip prosthesis has rarely been reported, and only a few cases have been documented. It is painful, disabling, costly, and may be associated with life-threatening sepsis even in a healthy individual. Removal of the implant is often required to eradicate the infection. Several early studies reported procedures to control the salmonella infection, but none described reconstruction of the destroyed hip joint. We present a case of salmonella sepsis 4 years after a total hip arthroplasty (THA). After prosthesis removal, radical debridement of the infected tissues, and administration of Imipenum (500 mg, 4 times daily), the systemic sepsis and hip infection were ameliorated. Four months later, a 2-stage revision THA was done for reconstruction of the hip joint. The clinical results 51 months following the THA procedure were satisfactory without an infectious reaction.
