Brief Tale of a Bacteraemia by Rhodococcus equi, With Concomitant Lung Mass: What Came First, the Chicken or The Egg?
Rhodococcus equi is an uncommon Gram positive, variably acid-fast pathogen, that appears as hard to treat mostly owing to the establishment of intracellular niches. Lack of interpretive criteria for susceptibility testing may lead to under-reporting or overestimation of resistances, whereas knowledge about this pathogen’s clinical impact may be affected by erroneous phenotype-based characterization at a genus and species level
Streptococcus dysgalactiae subsp. equisimilis: two cases of tonsillitis
We described two case reports of S. dysgalactiae subsp. equisimilis tonsillitis occurred from January 2005 to January 2007, among patients who come to our observation during these two years. These patients are paradigmatic of some conditions: adult age, absence of underlying diseases, outbreak of similar pharyngo-tonsillar sympyomatology, unsuccessful oral penicillin therapy, isolation of S. dysgalactiae subsp. equisimilis from throat swab, complete recovery after oral beta-lattamic antibiotic therapy, but total clearance of the microorganism only after oral macrolides administrations. Thus, the intracellular localization of S. dysgalactiae subsp. equismilis, could be in charge of the failure of beta-lattamic antibiotics therapy
Isolation of multidrug-resistant Enterobacter cloacae and comparison among clavulanate-tazobactam and sulbactam-synergy by using a double-disk synergy test
False negative results of double-disk synergy test with Enterobacter cloacae are common, as AmpC-enzymes may mask ESBLs elaboration. We increased the sensitivity of the method by using both clavulanate- and tazobactam/sulbactam; hence, we suggest to use all the three inhibitors to screen ESBLs in AmpC Ăź-lactamases producing organisms
Femoral Prosthesis Infection by Rhodotorula mucilaginosaâ–ż
This case report is a case history of a femoral prosthesis infection caused by Rhodotorula mucilaginosa in a human immunodeficiency virus patient. Though the pathogenicity of this organism for bone tissue has been previously reported, this is the first reported case of an orthopedic prosthesis infection by this species of the genus Rhodotorula
