Studies on lincosamide antibiotic resistance in methicillin-susceptible and -resistant staphylococci.

Lincomycin and clindamycin are still effective against anaerobic bacteria, and their antibacterial activity has also been indicated against gram-positive aerobic cocci, chiefly Staphylococcus aureus. The present emergency due to epidemiological circulation of Staphylococci, especially coagulase-negative, methicillin-resistant, and the question of the current validity of the lincosamides, induced us to study the activity of lincomycin and clindamycin against staphylococci belonging to different lyogroups in comparison to erythromycin. Clindamycin showed good antibacterial activity while methicillan-resistant strains showed an increase in resistance to erythromycin and lincomycin.

Size heterogeneity of ribosomal RNA in eukaryote evolution--1. rRNA molecular weights in species containing intact large ribosomal subunit RNA.

1. The molecular weights of the two major rRNA species (L-rRNA, large ribosomal subunit RNA, and S-rRNA, small ribosomal subunit RNA) of a variety of deuterostomia, green plants and fungi have been investigated by gel electrophoresis in 99% formamide, pH 9; the overall pattern obtained under these conditions differs to some extent from that deduced by electrophoresis in neutral-salt solutions. 2. The molecular weights of the deuterostomian S-rRNA species have been conserved at a value of 0.65 X 10(6), whereas those of the L-rRNA have been kept at 1.40 X 10(6) in the lower species but have increased to 1.55 X 10(6) in birds and to 1.65 X 10(6) in mammals. 3. The molecular weights of the L-rRNA and S-rRNA components of the green plants (Dycotyledons, Monocotyledons and Gymnosperms) have been generally conserved at 1.30 X 10(6) and 0.65 X 10(6). 4. The molecular weight of the L-rRNA of the fungi has been conserved at 1.36-1.38 X 10(6), being 0.1 X 10(6) daltons heavier than that of the plants; the S-rRNA exhibits a limited degree of variability, ranging between 0.65 X 10(6) and 0.72 X 10(6).

Crossed ureteral ectopia with solitary kidney.

A case of crossed ectopia with a solitary kidney in a 73-year-old man is presented. The fact that the kidney is normally situated and vascularized, and the presence of a second blind homolateral ureter leads us to conclude that this is a case of crossed ureteral ectopia in a solitary kidney. The embryogenesis of the malformation is discussed.
