Behavioural and fitness effects of experimental immune activation during incubation in a wild passerine

Ibis, Volume 168, Issue 3, Page 934-949, July 2026.
Incubation is vital for avian embryo development but demands significant parental investment, potentially at the cost of self‐maintenance and immune function. For example, the acute phase response (APR), a systemic reaction against inflammation, infection or tissue injury, can trigger sickness behaviours such as reduced activity and foraging.

Periodontitis and Periodontal Conditions in Systemically Healthy Children and Adolescents

Journal of Clinical Periodontology, Volume 53, Issue 7, Page 1100-1198, July 2026.
ABSTRACT Objective To answer the PICoS question ‘in systemically healthy children and adolescents (Population), what are the main features of periodontitis, necrotising periodontal diseases (NPD) and other periodontal conditions (periodontal abscesses, endo‐periodontal lesions, traumatic occlusal forces, prosthesis‐ and tooth‐related factors ...

Serotype-converting bacteriophages and O-antigen modification in Shigella flexneri

Trends in Microbiology, 2000
O-antigen modification (serotype conversion) in Shigella flexneri, which is an important virulence determinant, is conferred by temperate bacteriophages. Several serotype-converting phages have been isolated and preliminary characterization has identified the genes involved in O-antigen modification, and has also provided insight into the molecular ...

O-serotyping Providencia alcalifaciens

Journal of Clinical Microbiology, 1979
The O-serotyping scheme for Providencia was tested on Providencia alcalifaciens isolates collected mostly from two hospitals. The specificites of the somatic (O) antigens of P. alcalifaciens were found to be different from those of Providencia stuartii, and separation of the Providencia typing scheme to allow separate typing of each species led to more

O serotyping scheme for Enterobacter cloacae

Journal of Clinical Microbiology, 1983
A serotyping scheme for Enterobacter cloacae based on heat-stable somatic antigens is described. A total of 28 antisera were prepared in rabbits, and titers of agglutinins were high (greater than 640). Some cross-reactions were observed, and 11 sera required absorption before routine use.

Capsular and ‘O’ serotype determinants of Bacteroides fragilis

Infection, 1982
Forty-one strains of Bacteroides fragilis, 20 strains of other Bacteroides species and 14 strains of other genera were examined by the indirect immunofluorescent assay (IFA) using anticapsular serum. The sixty-one Bacteroides strains were 'O' serotyped by direct agglutination tests using absorbed antisera raised against 23 strains, each with a ...

Improved O-serotyping method for Serratia marcescens

Journal of Clinical Microbiology, 1989
In a previous study, we found that some O serotypes of Serratia marcescens, as defined by agglutination tests, were not based on lipopolysaccharide (LPS) O antigens. We developed a dot enzyme immunoassay with a high degree of LPS specificity and tested 104 distinct clinical strains.

Serotyping of Proteus rettgeri on the basis of O antigens

Canadian Journal of Microbiology, 1974
A serotyping system for Proteus rettgeri on the basis of 72 O antigens has been developed in a study of 324 strains obtained from widely distributed sources. In the investigation of the interrelations among the 72 O-type strains by cross-titration of each of the 72 anti-O sera with antigen of each of the O-type strains, both reciprocal and ...

Yersinia enterocolitica serotype O:3 is arthritogenic for mice

Microbial Pathogenesis, 1990
It is shown, for the first time, that Yersinia enterocolitica serotype O:3 is experimentally arthritogenic. Moreover, it is arthritogenic for the mouse, an optimal model for human yersiniosis. This arthritis can be induced by the oral route, the most common route in man.
