Tuberculosis (TB), caused by strains of Mycobacterium tuberculosis complex (M. tuberculosis), is a pulmonary infection that is spread by airborne droplet transmission. The development and spread of drug-resistant strains of M. tuberculosisgreatly jeopardize TB control efforts. We report the case of a previously healthy 43-year-old male, visiting from China, who presented to the emergency department complaining of hemoptysis of 10 days' duration. Cultures were positive for acid fast bacteria and negative for fungi...

Urinary tract infections due to enterobacteria producing extended spectrum beta-lactamases (ESBL-E) constitute a infectious risk, a major therapeutic challenge and can even lead, in some cases, to a deadlock beacuse of their multi-resistance to antibiotics. This study aimed to determine the epidemiological profile of uropathogenic ESBL-E and to describe their current level of resistance to antibiotics for a better patient management according to local data. We conducted a retrospective study of all ESBL-E strains isolated from all cytobacteriogical testing of urine (CBEU) treated in the Microbiology Laboratory at the Military Hospital of Moulay Ismail, Meknes over a period of three years (from 1 January 2013 to 31 December 2015)...

Resistance of clinical strains of Pseudomonas aeruginosa to aminoglycosides can result from production of transferable aminoglycoside-modifying enzymes, of 16S rRNA methylases, and/or mutational derepression of intrinsic multidrug efflux pump MexXY(OprM). The present study reports on characterization of a new type of mutants 4- to 8-fold more resistant to 2-deoxystreptamine derivatives (e.g., gentamicin, amikacin, tobramycin), as compared with wild-type strain PAO1. The genetic alterations of three in vitro mutants were mapped on fusA1, and found to result in single amino acid substitutions in domains II, III and V of elongation factor G (EF-G1A), a key component of translational machinery...

Background Lopinavir/ritonavir forms the backbone of current first-line antiretroviral regimens in young HIV-infected children. As multidrug-resistant (MDR) tuberculosis (TB) frequently occurs in young children in high-burden TB settings, it is important to identify potential interactions between MDR-TB treatment and lopinavir/ritonavir. We describe the pharmacokinetics of and potential drug-drug interactions between lopinavir/ritonavir and routine drugs used for MDR-TB treatment in HIV-infected children.Methods A combined population pharmacokinetic model was developed to jointly describe the pharmacokinetics of lopinavir and ritonavir in 32 HIV-infected children (16 on MDR-TB treatment with combinations of high-dose isoniazid, pyrazinamide, ethambutol, ethionamide, terizidone, a fluoroquinolone, and amikacin: and 16 without TB), who were established on a lopinavir/ritonavir-containing antiretroviral regimen...

Nine aph genes, including aph(2″)-Ib, Ic, Ig, If, If1, If3, Ih, aac(6')-Ie/aph(2″)-Ia, and aac(6')-Ie/aph(2″)-If2 were previously identified in Campylobacter. To measure the contribution of these alleles to aminoglycoside resistance, we cloned nine genes into the pBluescript and expressed them in E. coli DH5α. The nine aph expressed in E.coli showed varying levels of resistance to gentamicin, kanamycin and tobramycin. Three genes, aac(6″)-Ie/aph(2″)-Ia, aph2″-If1 and aph2″-Ig showed increased MICs to amikacin and five aph genes were transferrable...
