D Seinige, A Von Altrock, C Kehrenberg
We here report the occurrence of S. aureus in wild boars and characterize isolates genotypically and phenotypically in order to get knowledge about the occurrence of clonal lineages and genotypes in free-living wild animals. Forty-one S. aureus isolates obtained from 111 wild boars hunted in Lower Saxony, Germany, were investigated and compared to human and livestock isolates. The S. aureus belonged to multilocus sequence types ST1, ST7, ST30, ST133, ST425, ST804, ST890 and to the new ST3237, ST3238, ST3255 and ST3369...

The aim of this study was to characterize the immune response in Staphylococcus aureus chronically infected bovine mammary glands during active involution. Twenty-one Holstein non-pregnant cows in late lactation either uninfected or with chronic naturally acquired S. aureus intramammary infections (IMI) were included in this study. Cows were slaughtered at 7, 14 and 21 d after cessation of milking and samples for immunohistochemical analysis were taken. Protein expression of toll-like receptor 2 (TLR2) and TLR4 was significantly higher in S...

This longitudinal observational study was conducted to investigate the spontaneous effect of Giardia and Cryptosporidium infections on acute phase response (APR) in reindeer calves (Rangifer tarandus tarandus) in Finnish Lapland. Serum (n=609) and faecal samples (n=366) were collected from 54 reindeer calves aged zero to 33days. The samples were analysed for Giardia, Cryptosporidium, acute phase proteins (APP) and γ-globulins. Linear regression models were used to investigate associations of early Giardia infection (before 12days of life) with the response of APPs and acquiring of passive immunity...

REVIEW
J M B Prieto, M J B Felippe
Three populations of B cells develop in fetal life: B1, B2 and marginal zone B cells. B1 cells play important roles in innate immunity in contrast to B2 cells that perform the conventional roles in adaptive immunity. B1 cells were first identified in mice based on their expression of CD5 and spontaneous secretion of IgM. B1 cells were subsequently found to have unique developmental, phenotype, tissue distribution, and functional characteristics that differ from B2 cells. These phenotypic and functional differences allow B1 cells to play important roles in immunity and homeostasis, but be implicated in autoimmune disease...

During early lactation, dairy cows may present a transient immunosuppressive state and develop anaplasmosis caused by Anaplasma marginale. In this study, clinical anaplasmosis in dairy cattle in the Thrace region of Turkey was investigated with respect to within-herd prevalence, vertical transmission, and genetic diversity. In March and September 2015, thirty lactating cows showed primary clinical signs of anaplasmosis, including fever, anaemia, decreased milk yield, anorexia, and laboured breathing. Symptoms disappeared in most cows after administration of long-acting oxytetracycline, but nine of them (30%) died...

Here, we describe a novel approach that exploits an attenuated mutant of Salmonella enterica serovar Choleraesuis as carrier to deliver a plasmid encoding protein HisAK70. Subsequently, dendritic cells (DCs) were pulsed with this vaccine vector. The aim of this study was to evaluate the effectiveness of the prepared HisAK70-S. Choleraesuis-pulsed DCs (HisAK70-SAL DCs) against visceral leishmaniosis (VL). In our ex vivo model of infection, the prepared formulations could decrease parasite growth by up to 80% by augmenting the production of IL-12p40 and by reducing arginase activity (ARG)...

The intestinal epithelial cells reside in close proximity to myofibroblasts and microbiota, which are supposed to have an impact on intestinal stem cells fate and to influence processes of tissue maturation and regeneration. Mechanism underlying these phenomena and their diversity among vertebrates can be studied in 3D organoid cultures. We investigated the growth of chicken embryo intestinal epithelial organoids in Matrigel with and without Toll-like receptors (TLRs) stimulation. The organoid cultures contained also some myofibroblasts with potential to promote intestinal stem cell survival...

This study was conducted to assess the effect of colostrum quality and quantity on Cryptosporidium spp. calf diarrhoea in an intensive dairy cattle farm in Greece. Faecal samples were collected from 100 dairy calves randomly selected and born during all 4 seasons (March 2015 to May 2016) of the year. In total, 71% of the selected calves were positive for Cryptosporidium spp. oocysts. The statistical analysis revealed influence of colostrum quality on faecal score. Linear regression showed that the colostrum quantity during the first day of life was negatively associated with the number of Cryptosporidium spp...

There are two majorspecies of medically important lice that parasitize humans: Phthirus pubis, found in pubic hair, and Pediculus humanus. Pediculus humanus consists of two eco types that live in specific niches on the human host: body lice (Pediculus humanus humanus), found on the human body and clothing, and head lice (Pediculus humanus capitis), found on the scalp. To date, only body lice are known to be vectors of human disease; however, it has recently been reported that the DNA of several bacterial agents has been detected in head lice, raising questions about their role in the transmission of pathogens...

Babesiosis is a tick-borne zoonotic disease caused by haemoprotozoan parasites. The aim of this study were to assess markers of coagulation pathways in 25 dogs with naturally occurring babesiosis caused by B. canis, compared to 10 healthy controls. Protein C (PC) and antithrombin III (AT III) activity were assessed using a chromogenic substrate test, while levels of thrombin-antithrombin (TAT) complexes, activated protein C (APC) and endothelial protein C receptor were assessed using canine-specific ELISA. AT III activity was decreased as a result of a negative acute phase response, degradation by elastase, reduced availability of glycosaminoglycans, and, most importantly, consumption as a consequence of thrombin formation...

Experimental infection of Artibeus intermedius, the great fruit-eating bat, was performed with vampire bat rabies isolates. Bats (n=35) were captured in the wild and quarantined prior to experimental infection. No rabies antibodies were detected by rapid fluorescent focus inhibition test (RFFIT) prior to infection. Three doses of rabies virus (RV) and three different routes of infection were used. One out of 35 bats died without showing any clinical signs at day 14 and was positive for rabies. None of the 34 other bats showed clinical signs for rabies, but high antibody titers were detected post-inoculation, suggesting either innate immune response to the vampire bat rabies virus or possible pre-exposure to RV and inoculation leading to a booster effect...
