Local skin reaction (chancre) induced following inoculation of metacyclic trypanosomes in cattle by tsetse flies is dependent on CD4 T lymphocytes
(Blackwell Science Ltd, 2003)The first visible response in livestock to the bite of a trypanosomeinfected tsetse fly is the formation of a localized skin reaction, also known as a chancre. This is an inflammatory response in the skin associated ... -
Load and Prevalence of Antimicrobial-Resistant Escherichia coli from Fresh Goat Meat in Arusha, Tanzania

(American Journal of Research Communication, 2014)Bovine paratuberculosis or Johne’s disease is chronic, contagious granulomatous enteritis of cattle which is caused by Mycobacterium avium subspecies Paratuberculosis (MAP). The disease was first reported in Tanzania in ... -
CD5+ B lymphocytes are the main source of antibodies reactive with non-parasite antigens in Trypanosoma congolense-infected cattle
(Blackwell Science Ltd, 1997)Mice infected with African trypanosomes produce exceptionally large amounts of serum IgM, a major part of which binds to non-trypanosome antigens such as trinitrophenol and single-strand DNA. In this paper, we describe ... -
Genotype-Dependent Tumor Regression in Marek’s Disease Mediated at the Level of Tumor Immunity
(Springer, 2008-03-18)Marek’s disease (MD) of chickens is a unique natural model of Hodgkin’s and Non Hodgkin’s lymphomas in which the neoplastically-transformed cells over-express CD30 (CD30hi) antigen. All chicken genotypes can be infected ... -
Neutralization of Interleukin-10 Significantly Enhances Gamma Interferon Expression in Peripheral Blood by Stimulation with Johnin Purified Protein Derivative and by Infection with Mycobacterium avium subsp. paratuberculosis in Experimentally Infected Cattle with Paratuberculosis
(American Society for Microbiology, 2014-04)Monoclonal antibody neutralization of interleukin-10 (IL-10) increased Johnin purified protein derivativeinduced whole-blood gamma interferon (IFN- ) secretion 23-fold and also increased IFN- secretion ninefold following ... -
Transcriptional Innate Immune Response of the Developing Chicken Embryo to Newcastle Disease Virus Infection
(Frontiers in Genetics, 2018-02-27)Traditional approaches to assess the immune response of chickens to infection are through animal trials, which are expensive, require enhanced biosecurity, compromise welfare, and are frequently influenced by confounding ... -
CD14+ cells are required for IL-12 response in bovine blood mononuclear cells activated with Toll-like receptor (TLR) 7 and TLR8 ligands
(Elsevier, 2008)Single-stranded viral RNA (ssRNA) was recently identified as the natural ligand for TLR7 and TLR8. ssRNA sequences from viruses, as well as their synthetic analogues stimulate innate immune responses in immune cells from ... -
Prevalence of Antibiotic-Resistant Fecal Escherichia coli Isolates from Penned Broiler and Scavenging Local Chickens in Arusha, Tanzania
(Journal of Food Protection, 2016)We compared the prevalence of antibiotic-resistant Escherichia coli isolates from household-level producers of broiler (commercial source breeds) and local chickens in the Arusha District of Tanzania. Households were ... -
