TL;DR: This work provides further evidence of the utility of MALDI-TOF MS to identify morphologically and genetically highly similar tick species and indicates the potential of this tool for large-scale monitoring of tick populations, species distributions and host preferences.
Journal ArticleDOI
Development of field-applicable tests for rapid and sensitive detection of Candidatus Phytoplasma oryzae

TL;DR: An easy to use, rapid, sensitive and specific molecular assay for field diagnosis of Napier grass Stunt Disease and two murine monoclonal antibodies with high affinity and specificity to the immunodominant membrane protein IMP of Candidatus Phytoplasma oryzae were generated.
Journal ArticleDOI
Induction of humoral immune response to multiple recombinant Rhipicephalus appendiculatus antigens and their effect on tick feeding success and pathogen transmission.
Cassandra L. Olds,Cassandra L. Olds,Cassandra L. Olds,Stephen Mwaura,David Odongo,David Odongo,Glen A. Scoles,Richard P. Bishop,Claudia Daubenberger,Claudia Daubenberger +9 more
TL;DR: Evaluation of a multivalent vaccine cocktail of tick antigens for their ability to reduce R. appendiculatus feeding success and possibly reduce tick-transmission of T. parva in a natural host-tick-parasite challenge model highlights the importance of early evaluation of anti-tick vaccine candidates in biologically relevant challenge systems using the natural tick-host-Parasite combination.
Journal ArticleDOI
Draft Genome Sequence of “Candidatus Phytoplasma oryzae” Strain Mbita1, the Causative Agent of Napier Grass Stunt Disease in Kenya
Anne Fischer,Ivette Santana-Cruz,Lillian Wambua,Cassandra L. Olds,Charles A. O. Midega,Matthew Dickinson,Praphat Kawicha,Zeyaur R. Khan,Daniel K. Masiga,Joerg Jores,Bernd Schneider +10 more
TL;DR: This draft genome sequence of “Candidatus Phytoplasma oryzae” strain Mbita1 provides insight into its genomic organization and the molecular basis of pathogenicity.
Journal ArticleDOI
Rhipicephalus Appendiculatus Ticks Transmit Theileria Parva From Persistently Infected Cattle in the Absence of Detectable Parasitemia: Implications for East Coast Fever Epidemiology
TL;DR: It is shown that R. appendiculatus ticks are able to acquire T. parva parasites from infected cattle even in the absence of detectable parasitemia, a significant constraint to improvement of livestock production in sub-Saharan Africa.
