Combining citizen science and molecular diagnostic methods to investigate the prevalence of s.l. and in tick pools across Great Britain.

Lyme disease is the most common tick-borne disease and is caused by a group of bacteria known as lato (s.l.) complex.

Iterative Chemical Engineering of Vancomycin Leads to Novel Vancomycin Analogs With a High Therapeutic Index.

Vancomycin is a glycopeptide antibiotic that inhibits transpeptidation during cell wall synthesis by binding to the D-Ala-D-Ala termini of lipid II. For long, it has been used as a last resort antibiotic. However, since the emergence of the first vancomycin-resistant enterococci in 1987, vancomycin resistance has become widespread, especially in hospitals.

'Get in Early'; Biofilm and Wax Moth (Galleria mellonella) Models Reveal New Insights into the Therapeutic Potential of Clostridium difficile Bacteriophages.

Clostridium difficile infection (CDI) is a global health threat associated with high rates of morbidity and mortality. Conventional antibiotic CDI therapy can result in treatment failure and recurrent infection. C.

Prophage carriage and diversity within clinically relevant strains of Clostridium difficile.

Prophages are encoded in most genomes of sequenced Clostridium difficile strains. They are key components of the mobile genetic elements and, as such, are likely to influence the biology of their host strains. The majority of these phages are not amenable to propagation, and therefore the development of a molecular marker is a useful tool with which to establish the extent and diversity of C.

Diverse temperate bacteriophage carriage in Clostridium difficile 027 strains.

Background: The hypervirulent Clostridium difficile ribotype 027 can be classified into subtypes, but it unknown if these differ in terms of severity of C. difficile infection (CDI). Genomic studies of C.

Paternal exposure to ethylnitrosourea results in transgenerational genomic instability in mice.

Recent data shows that the effects of ionizing radiation are not restricted to the directly exposed parental germ cells, but can also manifest in their nonexposed offspring, resulting in elevated mutation rates and cancer predisposition. The mechanisms underlying these transgenerational changes remain poorly understood. One of the most important steps in elucidating these mechanisms is to investigate the initial cellular events that trigger genomic instability.

The combined effects of xeroderma pigmentosum C deficiency and mutagens on mutation rates in the mouse germ line.

Spontaneous and induced mutation rates at two expanded simple tandem repeat (ESTR) loci were studied in the germ line of xeroderma pigmentosum group C (Xpc) knockout mice defective in global genome nucleotide excision repair. Spontaneous and radiation-induced mutation rates in homozygous Xpc(-/-) males were significantly higher than those in isogenic wild-type (Xpc(+/+)) and heterozygous (Xpc(+/-)) mice. In contrast, exposure to the monofunctional alkylating agent ethylnitrosourea resulted in similar increases in ESTR mutation rates across all genotypes.

The effects of MSH2 deficiency on spontaneous and radiation-induced mutation rates in the mouse germline.

Mutation rates at two expanded simple tandem repeat (ESTR) loci were studied in the germline of mismatch repair deficient Msh2 knock-out mice. Spontaneous mutation rates in homozygous Msh2(-/-) males were significantly higher than those in isogenic wild-type (Msh2(+/+)) and heterozygous (Msh2(+/-)) mice. In contrast, the irradiated Msh2(-/-) mice did not show any detectable increases in their mutation rate, whereas significant ESTR mutation induction was observed in the irradiated Msh2(+/+) and Msh2(+/-) animals.

Validation of a novel ELISA for measurement of MDA-LDL in human plasma.

The involvement of oxidatively modified low density lipoprotein (LDL) in the development of CHD is widely described. We have produced two antibodies, recognizing the lipid oxidation product malondialdehyde (MDA) on whole LDL or ApoB-100. The antibodies were utilized in the development of an ELISA for quantitation of MDA-LDL in human plasma.
