Abstract
Abstract
Immune responses to pathogens and vaccination can be varied with some individuals inducing optimal responses while others do not. The host genetic profile, environment and previous microbial experience could influence an individual’s response, but the relative contribution, and interactions of these different factors remains largely unknown. Here, using various multi-omics, ecological and single cell approaches, we show that release of genetic inbred strains of mice, 129-SL, PWK and C57/B6 mice, to a rewilded environment and exposure of these rewilded and laboratory specific pathogen free control mice to a helminth parasite, Trichuris muris allowed us to assess the contribution and interaction of host genotype and environment to the immune cell landscape in the blood and secondary lymphoid organs. Critically, we find that the environment has the greatest effect on circulating blood immune cells while the genetic profile has the greatest effect on the mesenteric lymph node. We also observed significant interactions between the host genetic profile, environment, and infection status in their contribution to immune cell composition, with most of the effect driven by the cells of the adaptive immune system. These findings provide a model for contribution and interactions between genetics, environment, and helminth infection in the inter-individual variation of immune responses.

Abstract
Abstract
Type 2 inflammation is required for expulsion of intestinal helminth parasites and is characterized by immune cell activation, type 2 cytokine production, and increased mucin production by epithelial goblet cells. Previous studies show that the prostaglandin D2 (PGD2) receptor chemoattractant receptor-homologous molecule expressed on Th2 cells (CRTH2) promotes type 2 inflammation in the lung via effects on immune cells, but how CRTH2 influences helminth-induced type 2 inflammation in the intestine was unclear. Here we show that CRTH2-deficient mice cleared infection with the mouse-adapted helminth parasite Nippostrongylus brasiliensis more efficiently and had increased numbers of mucin-producing goblet cells in the small intestine post-infection compared to wild type mice, despite similar levels of worm establishment. These data suggest that CRTH2 restrains goblet cell responses during intestinal helminth infection, in contrast to its pro-inflammatory role in the lung. Consistent with this idea, bone marrow-chimeric mice in which only non-hematopoietic cells lacked CRTH2 also cleared parasites more efficiently than chimeric wild type mice and had increased numbers of small intestinal goblet cells. In addition, murine small intestinal organoids that were stimulated with type 2 cytokines downregulated expression of goblet cell-associated genes following culture with PGD2. Taken together, these data suggest that the PGD2-CRTH2 pathway suppresses epithelial goblet cell responses following helminth-induced type 2 inflammation in the intestine. These findings may inform the development and use of drugs that inhibit this pathway during intestinal type 2 inflammatory disease, such as food allergy.

Abstract
Available reports on brucellosis in Nigeria are largely confined to cattle while it is believed that other ruminants like sheep and goats are equally exposed to the disease. To have an insight into the role of goats in the epidemiology of brucellosis in Nigeria, we conducted a cross-sectional study between June 2011 and May 2013 to determine the seroprevalence of brucellosis in goats in some selected states in Nigeria. Serum samples were collected from goats at different locations and tested for antibodies to Brucella spp using the Rose Bengal Test (RBT), samples positive by RBT were further subjected to Competitive Enzyme Linked Immunosorbent Assay (cELISA). Data collected to determine risk factors were also analysed using chi-square and logistics regression statistics. Out of a total of 2827 samples tested from the different states (Benue = 331; Borno =195; Oyo = 2155; Sokoto = 146), we recorded an overall seroprevalence of 2.83% (Benue = 17.30%; Borno = 2.05%; Oyo = 0.60% and Sokoto = 0.00%) by RBT. The cELISA further supported 9.45% (7/74) of the total RBT positive samples. Logistic regression analysis showed that the location (p = 0.004) and source (p < 0.0001); are probable risk factors to be considered in the epidemiology of brucellosis with sex (p = 0.179); age (p = 0.791) and breed (p = 0.369) not playing any major role. Our findings reveal a relatively low seroprevalence of brucellosis among goats screened except for Benue State. Since most of the goats sampled in the present study were from the abattoirs, further farm level investigations are required to determine the role of goats in the epidemiology of brucellosis in Nigeria since they share common environment with sheep and cattle that are natural hosts of Brucella species which are of major public health threat.
