1/47. Fulminant infection by uncommon organisms in animal bite wounds.In 1995 and 1996, 215 patients exposed to different species of animals were treated at the Amarnath Polyclinic, Balasore, in india. Among them were two children infected by uncommon organisms, i.e., capnocytophaga canimorsus and pasteurella multocida; the patients recovered with appropriate antibiotic therapy.- - - - - - - - - - ranking = 1keywords = bite (Clic here for more details about this article) |
2/47. Hemolytic uremic syndrome due to capnocytophaga canimorsus bacteremia after a dog bite.The hemolytic uremic syndrome (HUS) is known to have several causes, including infectious diseases, drugs, pregnancy, and malignant disease. We report a patient who developed acute renal failure attributable to HUS in the course of capnocytophaga canimorsus bacteremia. Acute tubular necrosis as well as HUS should be considered as a cause of acute renal failure in the setting of capnocytophaga canimorsus bacteremia.- - - - - - - - - - ranking = 1keywords = bite (Clic here for more details about this article) |
3/47. Isolation, identification, and molecular characterization of strains of photorhabdus luminescens from infected humans in australia.We describe the isolation of photorhabdus (xenorhabdus) luminescens from four Australian patients: two with multiple skin lesions, one with bacteremia only, and one with disseminated infection. One of the patients had multiple skin lesions following the bite of a spider, while the lesions in the other patient were possibly associated with a spider bite. The source of infection for the remaining two patients is unknown. As a member of the family enterobacteriaceae, P. luminescens is unusual in that it fails to reduce nitrate and ferments only glucose and mannose. It gives negative reactions for lysine decarboxylase, arginine dihydrolase, and ornithine decarboxylase (Moeller). The species is motile, utilizes citrate, hydrolyzes urea, and usually produces a unique type of annular hemolysis on sheep blood agar plates incubated at 25 degrees C. A weak bioluminescence is the defining characteristic. P. luminescens is an insect pathogen and is symbiotically associated with entomopathogenic nematodes. Its isolation from human clinical specimens has been reported previously from the united states. Restriction fragment length polymorphism-PCR analysis of the 16S rRNA gene demonstrated a high level of similarity among the Australian clinical strains and significant differences between the Australian clinical strains and the U.S. clinical strains. However, numerical analyses of the data suggest that the two groups of clinical strains are more similar to each other than they are to the symbiotic strains found in nematodes. This is the first report of the isolation of P. luminescens from infected humans in australia and the second report of the isolation of this species from infected humans worldwide.- - - - - - - - - - ranking = 0.5keywords = bite (Clic here for more details about this article) |
4/47. Genital ulcer caused by human bite to the penis.BACKGROUND AND OBJECTIVES: Human bite injuries, while less frequent than cat or dog bites, usually stem from aggressive behavior, sports, or sexual activity. It has been thought that human bites have a higher rate of infection than animal bites, but this view is likely skewed because of the frequency of closed fist injuries presenting to emergency rooms. Human bites to the genitalia also occur, but are not often reported because of embarrassment. GOAL OF THE STUDY: We report a genital ulceration after a human bite to the penis and review appropriate diagnostic and therapeutic maneuvers. STUDY DESIGN: This article reports the development of a severe genital ulcer associated with a human bite to the penis secondarily infected, as verified by culture, with an oral flora organism eikenella corrodens. RESULTS: The genital ulceration healed after appropriate antibiotic therapy. CONCLUSIONS: Treatment of human bites focuses on obtaining an accurate history and performing a salient physical examination, as well as early irrigation and debridement. Transmission of communicable disease should be considered as a possible consequence. Prophylactic antibiotic treatment and primary closure of wounds continue to be areas of controversy.- - - - - - - - - - ranking = 3keywords = bite (Clic here for more details about this article) |
5/47. eikenella corrodens vertebral osteomyelitis secondary to direct inoculation: a case report.STUDY DESIGN: A case report. OBJECTIVE: To present a unique method of inoculation with an unusual bacterial organism, eikenella corrodens, which led to vertebral osteomyelitis and to heighten awareness of different bacterial organisms that may cause orthopedic infections. SUMMARY OF BACKGROUND DATA: E. corrodens has been known to cause orthopedic infections for more than 20 years. The usual mechanism is from "Fight bite" injuries to the hand or metacarpal phalangeal joint. Eikenella osteomyelitis of the vertebral body is extremely rare. methods: A 65-year-old man from indonesia developed slowly progressive vertebral collapse and worsening neck pain. history suggested a previous pharyngeal injury while eating fish. work up for malignancy was negative, and imaging studies were suggestive of osteomyelitis. An open biopsy and culture as well as fusion were performed for treatment of the osteomyelitis. RESULTS: After a complete work up was undertaken, cultures grew out E. corrodens as the causative organism of this patient's osteomyelitis. Computed tomography scan and history were consistent with inoculation of the paravertebral space with E. corrodens secondary to a fish bone transgressing the patient's pharynx. The patient was treated with surgery and the appropriate antibiotics and healed without any significant sequela. CONCLUSION: Vertebral osteomyelitis due to E. corrodens is extremely rare. Direct inoculation as a cause of vertebral osteomyelitis with Eikenella has never been reported. If diagnosed properly with appropriate cultures and antibiotic sensitivities, Eikenella osteomyelitis can be treated successfully according to standard orthopedic practices including debridement, fusion, and appropriate antibiotics. awareness of unusual bacteria as potential causative organisms of osteomyelitis is imperative for appropriate treatment.- - - - - - - - - - ranking = 0.25keywords = bite (Clic here for more details about this article) |
6/47. Infective endocarditis complicated with progressive heart failure due to beta-lactamase-producing cardiobacterium hominis.We describe a 66-year-old woman with infective endocarditis due to cardiobacterium hominis whose condition, complicated by severe aortic regurgitation and congestive heart failure, necessitated aortic valve replacement despite treatment with ceftriaxone followed by ciprofloxacin. The blood isolate of C. hominis produced beta-lactamase and exhibited high-level resistance to penicillin (MIC, >==256 microgram/ml) and reduced susceptibility to vancomycin (MIC, 8 microgram/ml).- - - - - - - - - - ranking = 0.25keywords = bite (Clic here for more details about this article) |

8/47. Polymicrobial tenosynovitis with pasteurella multocida and other gram negative bacilli after a Siberian tiger bite.Mammalian bites present a considerable clinical problem because they are often associated with bacterial infections. pasteurella multocida is a microorganism that commonly infects both canine and small feline bites. Zoonotic infections developing after large feline bites have been recognised, although their reports are limited. We describe a 35 year old man who was bitten by a Siberian tiger and who developed infectious tenosynovitis secondary to P multocida, Bergeyella (Weeksella) zoohelcum, and Gram negative bacteria most like CDC group EF-4b and comamonas species. The latter three bacteria have not been isolated previously from large feline bite wounds.- - - - - - - - - - ranking = 2keywords = bite (Clic here for more details about this article) |
9/47. Hemolytic uremic syndrome after capnocytophaga canimorsus (DF-2) septicemia.A 66-year-old man developed a hemolytic uremic syndrome (HUS) with acute renal failure, thrombocytopenia, fragmented red cells in the blood film and elevated serum LDH following a capnocytophaga canimorsus (DF-2) infection after a dog bite. He was treated with antibiotics, plasmapheresis and hemodialysis. Although hematologic values improved, the patient remained hemodialysis-dependent for six months. In the literature several cases of renal failure following capnocytophaga canimorsus septicemia have been described, caused by hypotension or disseminated intravascular coagulation (DIC). In our patient there were no signs of hypotension or extensive DIC. A few case reports described HUS and thrombotic thrombocytopenic purpura (TTP) following DF-2 sepsis.- - - - - - - - - - ranking = 0.25keywords = bite (Clic here for more details about this article) |
10/47. capnocytophaga cynodegmi cellulitis, bacteremia, and pneumonitis in a diabetic man.capnocytophaga cynodegmi (formerly "DF-2 like organism"), a commensal organism of the canine oral cavity, is a capnophilic, gram-negative, facultative bacillus. C. cynodegmi has rarely been encountered in human diseases. We report the first known case of cellulitis, bacteremia, and pneumonitis caused by C. cynodegmi in a diabetic man from central india following a dog bite.- - - - - - - - - - ranking = 0.25keywords = bite (Clic here for more details about this article) |
