1/29. Primary cutaneous nocardiosis in a husband and wife.A 62-year-old woman suffered from acute purulent skin disease with multiple subcutaneous abscesses. At the same time, her 65-year-old husband presented with multiple subcutaneous nodules along the lymphatic vessels of his right arm. Both had a history of a minor scratch by a thorn of a bush at the site of infection. nocardia was identified as causative bacterium from the woman's lesions. Therefore the rare phenomenon of 2 different forms of acute primary cutaneous nocardiosis after simultaneous infection, lymphocutaneous infection, and superficial skin infection was diagnosed.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
2/29. Insect wing case: unusual foreign body.PURPOSE: To report five cases of insect wing case foreign body. methods: Clinical presentation, investigations, management, and outcome of these cases are discussed. RESULTS: Five patients, four males and one female, in the age group from 4 to 55 years presented with an insect wing case embedded in the cornea or peripheral limbus. All patients were relatively asymptomatic, and the foreign body was associated with vascularization and infiltration. culture of the foreign body after removal showed staphylococcus epidermidis in two cases and corynebacterium species and mycobacterium fortuitum in one case each. All patients responded to removal of the wing case foreign body and treatment with topical ciprofloxacin (0.3%). CONCLUSION: Insect wing case is an unusual foreign body and produces minimal symptoms and may be associated with infective agents in some patients.- - - - - - - - - - ranking = 2keywords = bacterium (Clic here for more details about this article) |
3/29. wound infection due to vibrio vulnificus in spain.vibrio vulnificus is a gram-negative rod that can cause septicaemia and skin lesions, usually in patients with underlying illnesses such as chronic liver disease or diabetes mellitus. Infections caused by this bacterium are unusual in spain. A case of skin infection due to vibrio vulnificus is reported in a patient whose abraded skin on his left leg came into contact with seawater. The patient died suddenly, probably due to septicaemia or bacteraemia caused by this organism. vibrio vulnificus infection must be considered in the differential diagnosis of septicaemia, skin lesions and wound infections, particularly when a patient reports a history of contact with seawater.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
4/29. Lymphocutaneous nocardia brasiliensis infection acquired from a cat scratch: case report and review.nocardia brasiliensis is a bacterium that is most commonly found in the soil. Traumatic inoculation of N. brasiliensis into the skin is the most typical mode of acquisition of infection due to this organism. To the best of my knowledge, I report the first case of lymphocutaneous N. brasiliensis disease from a penetrating cat scratch of the skin, thereby establishing cats as vehicles for the transmission of this infection. Treatment with penicillin produced a rapid resolution of all signs and symptoms of infection. The efficacy of penicillin against the N. brasiliensis isolate recovered from this patient was highly unusual. In general, penicillin has limited therapeutic value since these organisms elaborate beta-lactamase. sulfonamides remain the drugs of choice for the treatment of these infections. These soil-borne organisms are most likely carried on the claws of cats and may establish infection after percutaneous inoculation. A high index of suspicion for N. brasiliensis soft-tissue infection is required since a delayed or missed diagnosis may be associated with progressive local disease and/or widespread disseminated infection.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
5/29. mycobacterium marinum: a case of skin granuloma complicated by tenosynovitis of the extensors.The authors report the case of a male patient who owned a tropical aquarium and who developed a M. marinum skin infection of the wrist. The clinical findings and microbiological features of the case are described, as are the difficulty in providing a prompt diagnosis, and the need for surgical treatment and the use of antibiotics to treat the infection.- - - - - - - - - - ranking = 4keywords = bacterium (Clic here for more details about this article) |
6/29. A case of chromobacterium infection after car accident in korea.chromobacterium violaceum is a gram negative straight rod, 0.8-1.2 by 2.5 to 6.0 m, which is motile by one polar flagella and one to four lateral flagella. The organism inhabits soil and water and is often found in semitropical and tropical climates. Infections in humans are rare. We report a case of infection caused by strains of C. violaceum. A 38-year-old male patient was admitted to KyungHee University Hospital, Seoul, korea on July 28th, 2003, after a car accident. The patient had multiple trauma and lacerations. He had an open wound in the left tibial area from which C. violaceum was isolated. The strain was resistant to ampicillin, tobramycin, ampicillin/sulbactam, ceftriaxone and cefepime, but was susceptible to amikacin, gentamicin, ciprofloxacin, levofloxacin, trimethoprim/sulfamethoxazole and piperacillin/tazobactam. The patient was treated successfully by debridement, cephapirin sodium and astromicine sulfate.- - - - - - - - - - ranking = 5keywords = bacterium (Clic here for more details about this article) |
7/29. capnocytophaga canimorsus mycotic abdominal aortic aneurysm: why the mailman is afraid of dogs.We describe the first case report of a mycotic abdominal aortic aneurysm secondary to capnocytophaga canimorsus in an immunocompetent 65-year-old man. The exposure occurred after his dog scratched his arm and subsequently licked the wound. A review of C. canimorsus, a rarely pathogenic but potentially devastating bacterium, is also presented.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
8/29. Description of Mycobacterium conceptionense sp. nov., a mycobacterium fortuitum group organism isolated from a posttraumatic osteitis inflammation.A nonpigmented rapidly growing mycobacterium was isolated from wound liquid outflow, bone tissue biopsy, and excised skin tissue from a 31-year-old woman who suffered an accidental open right tibia fracture and prolonged stay in a river. The three isolates grew in 3 days at 24 to 37 degrees C. 16S rRNA sequence analyses over 1,483 bp showed that they were identical and shared 99.7% (4-bp difference) sequence similarity with that of Mycobacterium porcinum, the most closely related species. Partial rpoB (723 bp) sequence analyses showed that the isolates shared 97.0% sequence similarity with that of M. porcinum. Further polyphasic approaches, including biochemical tests, antimicrobial susceptibility analyses, and hsp65, sodA, and recA gene sequence analysis, as well as % G C determination and cell wall fatty acid composition analysis supported the evidence that these isolates were representative of a new species. Phylogenetic analyses showed the close relationship with M. porcinum in the mycobacterium fortuitum group. The isolates were susceptible to most antibiotics and exhibited evidence for penicillinase activity, in contrast to M. porcinum. We propose the name Mycobacterium conceptionense sp. nov. for this new species associated with posttraumatic osteitis. The type strain is D16(T) (equivalent to CIP 108544(T) and CCUG 50187(T)).- - - - - - - - - - ranking = 12keywords = bacterium (Clic here for more details about this article) |
9/29. actinobacillus spp. and related bacteria in infected wounds of humans bitten by horses and sheep.We describe the isolation of actinobacillus lignieresii and an A. equuli-like bacterium from an infected horse-bite wound in a 22-year-old stable foreman and A. suis from a bite injury in a 35-year-old man who had been attacked by a horse. A. lignieresii was also isolated in pure culture from an infected sheep-bite wound in a rural worker. These species of the genus actinobacillus are primarily associated with animals and animal diseases and are rarely isolated from humans. The purpose of this report is to raise awareness of the possible occurrence of actinobacillus spp. in bite wounds inflicted by farm animals and to discuss the difficulties encountered in the identification of species of actinobacillus and related bacteria.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
10/29. erythromycin failure with subsequent pasteurella multocida meningitis and septic arthritis in a cat-bite victim.We report the case of a 75-year-old woman who developed pasteurella multocida meningitis and septic arthritis while being treated for a cat-bite wound infection with erythromycin. review of the literature revealed that erythromycin has poor in vitro activity against this bacterium and has been associated with serious clinical failures. We recommend that erythromycin not be prescribed for empiric therapy of established animal-bite infections. Suggestions for optimal empiric therapy of animal-bite infections and the differential diagnosis of severe cat-bite-associated sepsis are discussed.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
