Performance Of A Prototype Baited-Trap In Attracting And Infecting The Tick Amblyomma Variegatum (Acari: Ixodidae) In Field Experiments, R. O. Maranga, A. Hassanali, G. P. Kaaya, J. M. Mueke

All Peer-Reviewed Publications

Investigations were commenced to study the potential use of the fungi, Beauveria bassiana, Metarhizium anisopliae, and the attraction-aggregation- attachment pheromone (AAAP) for the control of Ambloyomma variegatum as an environmentally friendly technology. The objective of the study was to develop and test a device, which could be used for pheromone and carbon dioxide delivery and infection of ticks with the fungi in an attempt to control the tick populations in the vegetation. Using a pheromone-baited device treated with the fungi mixture, 79% of the ticks released were attracted and exposed to the fungi and of these, 78% died during incubation …

Initial Evaluation Of Novel Preparations Of Bordetella Avium By Determination Of Antibody Response Titers, Joel Gallagher, Stacy Higgins, Luc Berghman, Billy Hargis

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The efficacy of killed vaccines generally is not equal to live vaccines. However, due to safety and ease of production, they remain a vital part of controlling and preventing diseases. In this study, the immune response to four different vaccination preparation techniques for the agent of bordetellosis of turkeys, Bordetella avium (BA), was compared. Preparation/inactivation techniques included (1) formalin inactivation, (2) opsonization of formalin-inactivated BA, (3) buffered acetic-acid BA inactivation, or (4) opsonization of buffered acetic-acid-inactivated BA. Non-adjuvated suspensions containing equal antigen mass were administered subcutaneously (0.2 mL) at day-of-hatch in all cases. For each treatment (N=40/treatment), plasma samples were …

Premature Induction Of An Immunosuppressive Regulatory T Cell Response During Acute Simian Immunodeficiency Virus Infection, Jacob D. Estes, Qingsheng Li, Matthew R. Reynolds, Stephen W.

Here we report the results of an investigation into the possibility that one mechanism responsible for the establishment of persistent human immunodeficiency virus infection is an early regulatory T (T_reg) cell response that blunts virus- specific responses. Using the simian immunodeficiency virus (SIV)–infected rhesus macaque model, we show that, indeed, viral replication and immune activation in lymphatic tissue drive a premature immunosuppressive response, with dramatic increases in the frequencies of CD4⁺CD25⁺FOXP3⁺ Treg cells, transforming growth factor–β1⁺ cells, interleukin–10+ cells, and indoleamine 2,3-dioxygenase+CD3⁺ cells.When we compared SIV infection with rhesus cytomegalovirus (RhCMV) …

Molecular Characterization Of A Tsetse Fly Midgut Proteolytic Lectin That Mediates Differentiation Of African Trypanosomes, Laila U. Abubakar, Wallace D. Bulimo, Francis J. Mulaa, Ellie O. Osir

All Peer-Reviewed Publications

Differentiation of bloodstream-form trypanosomes into procyclic (midgut) forms is an important first step in the establishment of an infection within the tsetse fly. This complex process is mediated by a wide variety of factors, including those associated with the vector itself, the trypanosomes and the bloodmeal. As part of an on-going project in our laboratory, we recently isolated and characterized a bloodmeal-induced molecule with both lectin and trypsin activities from midguts of the tsetse fly, Glossina longipennis [Osir, E.O., Abubakar, L., Imbuga, M.O., 1995. Purification and characterization of a midgut lectin-trypsin complex from the tsetse fly, Glossina longipennis. Parasitol. Res. …
