Splenic abscesses are caused by Staphylococcus aureus, Streptococcus and bacteria belonging to the family Enterobacteriaceae. We report a case of splenic abscess caused by an unusual serotype of Salmonella. A 55 year old man was admitted with complaints of fever and abdominal pain. On the basis of clinical findings and laboratory reports, a diagnosis of chronic myeloid leukemia was made. Ultrasonography of the abdomen revealed a single large cystic lesion in the spleen. Percutaneous drainage of the abscess was carried out. Salmonella enterica serotype Worthington was isolated from a pus sample taken from the abscess. The isolate was resistant to ampicillin, gentamicin, cefotaxime, chloramphenicol and tetracycline, and sensitive to amikacin and norfloxacin. Serotype Worthington is an emerging pathogen. This is the first report of isolation of this serotype from a splenic abscess. In seriously ill patients, such infections should be treated with a combination of antibiotics to circumvent problems with multidrug resistance.
The management of a mastoid subperiosteal abscess has traditionally required mastoidectomy. With the improvement of antibiotic therapy current literature supports the treatment of uncomplicated acute mastoiditis with myringotomy and intravenous antibiotics. Treatment of a mastoid subperiosteal abscess with tympanostomy tube insertion, intravenous antibiotics, and postauricular incision and drainage of the abscess avoids the morbidity and potential complications of mastoid surgery in young children. Three patients diagnosed with a mastoid subperiosteal abscess were managed in this way. The outcome of their treatment has been documented with lengthy otologic follow-up. Complete resolution of the acute infectious process was achieved in all cases with no evidence of recurrent disease.
Potent nanomolar inhibitors of Staphylococcus aureus methionyl tRNA synthetase have been derived from a file compound high throughput screening hit. Optimized compounds show excellent antibacterial activity against staphylococcal and enterococcal pathogens, including strains resistant to clinical antibiotics. Compound 11 demonstrated in vivo efficacy in an S. aureus rat abscess infection model.
