A single dose of 100 mg ofloxacin was compared with a multiple dose of cotrimoxazole in lower urinary tract infections in 137 women. The elimination rate was significantly lower in the single dose treated group of patients in spite of all strains being in vitro susceptible in this group.
A 20 year-old Brazilian man, having mover to French Guiana a few months earlier, presented with multiple disseminated cutaneous lesions, predominating on the face, and composed of multiple nodules and two ulcerations. The clinical examination also revealed voluminous superficial lymph nodes and ulcerations of the pharynx and larynx. Direct examination, anatomopathology and culture of cutaneous biopsies revealed specific images of Paracoccidioides brasiliensis. HIV serology was negative. Treatment combining cotrimoxazole and itraconazole eliminated the lesions in one month.

ZOIs of the Coloplast Titan for each of the medicated solutions were compared with ZOI created by undipped strips of a sterile InhibiZone coated IPP placed on plates of the identical bacteria.

The yeast spindle pole body (SPB) is the functional equivalent of the mammalian centrosome. Centrosomes and SPBs duplicate exactly once per cell cycle by mechanisms that use the mother structure as a platform for the assembly of the daughter. The conserved Sfi1 and centrin proteins are essential components of the SPB duplication process. Sfi1 is an elongated molecule that has, in its center, 20 to 23 binding sites for the Ca(2+)-binding protein centrin. In the yeastSaccharomyces cerevisiae, all Sfi1 N termini are in contact with the mother SPB whereas the free C termini are distal to it. During S phase and early mitosis, cyclin-dependent kinase 1 (Cdk1) phosphorylation of mainly serine residues in the Sfi1 C termini blocks the initiation of SPB duplication ("off" state). Upon anaphase onset, the phosphatase Cdc14 dephosphorylates Sfi1 ("on" state) to promote antiparallel and shifted incorporation of cytoplasmic Sfi1 molecules into the half-bridge layer, which thereby elongates into the bridge. The Sfi1 C termini of the two Sfi1 layers localize in the bridge center, whereas the N termini of the newly assembled Sfi1 molecules are distal to the mother SPB. These free Sfi1 N termini then assemble the new SPB in G1phase. Recruitment of Sfi1 molecules into the anaphase SPB and bridge formation were also observed inSchizosaccharomyces pombe, suggesting that the Sfi1 bridge cycle is conserved between the two organisms. Thus, restricting SPB duplication to one event per cell cycle requires only an oscillation between Cdk1 kinase and Cdc14 phosphatase activities. This clockwork regulates the "on"/"off" state of the Sfi1-centrin receiver.

We report a case of apparent malaria infection presented with a syndrome of painless, generalized lymphadenopathy without granulomas shortly after exposure to fresh water in rural West Africa. Residual infection with Massilia timonae was diagnosed and successfully treated with co-trimoxazole.

All patients with a culture positive for E. coli during a 6-year study period.
The aim of this study was to characterize methicillin-resistant Staphylococcus aureus (MRSA) isolates recovered from different infectious sites of hospitalized patients at two university hospitals. Fourteen isolates were analyzed by repetitive sequence based PCR (Rep-PCR), randomly amplified polymorphic DNA assay (RAPD-PCR), and pulsed-field gel electrophoresis (PFGE). We found that a prevalent clone of MRSA, susceptible to rifampin, minocycline, and trimethoprim/sulfamethoxazole (RIF(s), MIN(s), TMS(s)) was present in both hospitals in replacement of the multiresistant MRSA South American clone, previously described in these hospitals. The staphylococcal chromosomal cassette (SCCmec) type I element was detected in this new clone.
Brucellosis (infection with Brucella spp.) is a common zoonosis in many parts of the world. Human brucellosis is a multisystem disease that may present with a broad spectrum of clinical manifestations. Treatment of brucellosis must effectively control acute illness and prevent complications and relapse. The choice of regimen and duration of antimicrobial therapy should be based on the presence of focal disease and underlying conditions which contraindicate certain specific antibiotics. The regimen of first choice is combination therapy with doxycycline for 45 days and streptomycin for 14 days. Gentamicin or netilmicin for the first 7 days may be substituted for streptomycin. Second-choice regimens consist of combinations of doxycycline and rifampicin (rifampin) for 45 days, or monotherapy with doxycycline for 45 days. Surgery should be considered for patients with endocarditis, cerebral or epidural abscess, spleen abscess or other abscesses which are antibiotic-resistant. Tetracyclines are generally contraindicated for pregnant patients and children < 8 years old. Rifampicin 900 mg once daily for 6 weeks is considered the drug of choice for treating brucellosis in pregnant women. In children < 8 years old the preferred regimen is rifampicin with cotrimoxazole (trimethoprim-sulfamethoxazole) for 45 days. An alternative regimen consists of a combination of rifampicin for 45 days with gentamicin 5 to 6 mg/kg/day for the first 5 days.
