Nontoxigenic Corynebacterium diphtheriae: An Emerging Pathogen in England and Wales?

Emerging Infectious Diseases, 2000
Confirmed isolates of nontoxigenic Corynebacterium diphtheriae in England and Wales increased substantially from 1986 to 1994. Ribotyping of 121 isolates confirmed in 1995 showed that 90 were of a single strain isolated exclusively from the throat; none ...

Complexation of CcmB with CcmACD safeguards heme translocation for cytochrome c maturation

mLife, Volume 4, Issue 1, Page 29-44, February 2025.
Abstract Cytochrome c maturation (CCM), a posttranslational modification involving covalent attachment of heme to polypeptides (apocyt c), is essential for the activity and cellular function of cytochromes c. Here, we identify and substantiate CcmB as heme translocase in bacteria.

Insights into the flexibility of the domain‐linking loop in actinobacterial coproheme decarboxylase through structures and molecular dynamics simulations

Protein Science, Volume 34, Issue 2, February 2025.
Abstract Prokaryotic heme biosynthesis in Gram‐positive bacteria follows the coproporphyrin‐dependent heme biosynthesis pathway. The last step in this pathway is catalyzed by the enzyme coproheme decarboxylase, which oxidatively transforms two propionate groups into vinyl groups yielding heme b.

Antibiotic Susceptibility of Zoonotic Bacteria Isolated From Oral Cavities of Indigenous Dogs From Semi‐Urban Areas in Uganda

Veterinary Medicine and Science, Volume 11, Issue 1, January 2025.
Dog bites lead to bacterial infections. Isolation and identification of zoonotic bacterial species from the oral cavities of indigenous dogs using biochemical tests were carried out. The antibiotic susceptibility profile of the commonly identified bacteria species was established using Kirby–Bauer disk diffusion approach.

Örjan Ouchterlony and the antigen–antibody double diffusion‐in‐gel: a survey

APMIS, Volume 133, Issue 1, January 2025.
The Swedish scientist Örjan Ouchterlony published four ground‐breaking papers 1948–1966 in Acta Pathol Microbiol Scand where he described a new method of antigen–antibody reactions in gel. He described and defined the ‘reaction of identity’ and ‘reaction of partial identity’ when he used related antigens and ‘reaction of non‐identity’ when he used non ...
