Identification, molecular characterization, and experimental transmission of a new hemoplasma isolate from a cat with hemolytic anemia in Switzerland.
Barbara Willi,Felicitas S Boretti,Valentino Cattori,Séverine Tasker,Marina L. Meli,Claudia E Reusch,Hans Lutz,Regina Hofmann-Lehmann +7 more
TL;DR: A quantitative real-time PCR assay specific for this newly discovered agent was developed, which will be a prerequisite for the diagnosis of infections with the new hemoplasma isolate.

Concurrent infections with vector-borne pathogens associated with fatal hemolytic anemia in a cattle herd in Switzerland
Regina Hofmann-Lehmann,Marina L. Meli,Ute M. Dreher,E. Gönczi,Peter Deplazes,Ueli Braun,Monika Engels,Jörg Schüpbach,Kaspar Jörger,R Thoma,Christian Griot,Katharina D.C. Stärk,Barbara Willi,Joseph Schmidt,Katherine M. Kocan,Hans Lutz +15 more
TL;DR: It is concluded that A. marginale was the major cause of the hemolytic anemia, while coinfections with other agents exacerbated the disease.

TL;DR: 9 out of 15 wild felid species from three different continents were found to be infected with feline hemoplasmas, andylogenetic analyses of the 16S rRNA and the partial RNase P gene revealed that most hemoplasma isolates exhibit high sequence identities to domestic cat-derived isolates, although some isolates form different subclusters within the phylogenetic tree.
Real-Time PCR Investigation of Potential Vectors, Reservoirs, and Shedding Patterns of Feline Hemotropic Mycoplasmas
Barbara Willi,Felicitas S Boretti,Marina L. Meli,Marco V. Bernasconi,Simona Casati,Daniel Hegglin,Maria Puorger,Harold Neimark,Valentino Cattori,Nicole Wengi,Claudia E Reusch,Hans Lutz,Regina Hofmann-Lehmann +12 more
TL;DR: The results suggest that besides an ostensibly indirect transmission by fleas, direct transmission through saliva and feces at the early phase of infection could play a role in the epizootiology of feline hemotropic mycoplasmas.

Phylogenetic Analysis of “Candidatus Mycoplasma turicensis” Isolates from Pet Cats in the United Kingdom, Australia, and South Africa, with Analysis of Risk Factors for Infection
Barbara Willi,Séverine Tasker,Felicitas S Boretti,Marcus G. Doherr,Valentino Cattori,Marina L. Meli,Remo G. Lobetti,Richard Malik,Claudia E Reusch,Hans Lutz,Regina Hofmann-Lehmann +10 more
TL;DR: Investigation of the presence and clinical importance of “Candidatus Mycoplasma turicensis” infection in pet cats outside of Switzerland and the molecular characterization of isolates from different countries revealed significantly decreased PCV values are observed in cats coinfected with other feline hemoplasmas.
