Professor John Fincham was one of the UK's leading geneticists, with a remarkably broad knowledge of the subject across the biological kingdoms. He became an international leader through being at the forefront of microbial genetics as some of the founding principles of the relationships between gene structure, activity and enzyme functions were being uncovered. He spearheaded discoveries from the one gene-one enzyme concept, through genetic complementation, protein structure and recombination. Much of his experimental microbial research centered on the genetic and enzyme variants of glutamate dehydrogenase in the fungus Neurospora. He also brought his outstanding mind and comprehensive interest in genetics to the then obscure features of unstable genes and transposable elements in plants. His standing was recognized by holding prestigious chairs in Leeds, Edinburgh and Cambridge universities. He was a talented writer, producing several textbooks and especially the leading text Fungal genetics. He was also a practitioner and lover of sports and in his early career was politically active. His successes in life made him an extraordinarily talented man who achieved much as a leader in genetics in the UK and internationally.

The aim of this study was to determine the genetic diversity of Giardia duodenalis present in a human population living in a northern Ecuadorian rain forest. All Giardia positive samples (based on an ELISA assay) were analysed using a semi-nested polymerase chain reaction-restriction fragment length polymorphism assay that targets the glutamate dehydrogenase (gdh) gene; those amplified were subsequently genotyped using NlaIV and RsaI enzymes. The gdh gene was successfully amplified in 74 of 154 ELISA positive samples; 69 of the 74 samples were subsequently genotyped. Of these 69 samples, 42 (61%) were classified as assemblage B (26 as BIII and 16 as BIV), 22 (32%) as assemblage A (3 as AI and 19 as AII) and five (7%) as mixed AII and BIII types. In this study site we observe similar diversity in genotypes to other regions in Latin America, though in contrast to some previous studies, we found similar levels of diarrheal symptoms in those individuals infected with assemblage B compared with those infected with assemblage A.

Giardia duodenalis is one of the most prevalent enteroparasites in children. This parasite produces several clinical manifestations. The aim of this study was to determine the prevalence of genotypes of G. duodenalis causing infection in a region of southeastern Mexico. G. duodenalis cysts were isolated (33/429) from stool samples of children and molecular genotyping was performed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis, targeting the triosephosphate isomerase ( tpi ) and glutamate dehydrogenase ( gdh ) genes. The tpi gene was amplified in all of the cyst samples, either for assemblage A (27 samples) or assemblage B (6 samples). RFLP analysis classified the 27 tpi -A amplicons in assemblage A, subgenotype I. Samples classified as assemblage B were further analysed using PCR-RFLP of the gdh gene and identified as assemblage B, subgenotype III. To our knowledge, this is the first report of assemblage B of G. duodenalis in human clinical samples from Mexico.
