Abstract
The genetic loci influencing individual resistance to Mycobacterium avium subsp. paratuberculosis (MAP) infection are still largely unknown. In the current study, we searched for genetic loci associated with resistance to MAP infection by evaluating the performance of monocyte-derived macrophages (MDMs) isolated from the peripheral blood of 75 healthy Holsteins cows and infected ex vivo with MAP. Bacterial load (log colony-forming units, log CFUs) within MDMs was quantified at 2 h and 7 days p. i. using a BACTEC MGIT 960 instrument. In addition, the expression levels of some genes with important roles in the innate immune response including epiregulin (EREG), complement component C3 (C3), galectin-9 (Gal9), and nitric oxide (NO-) were measured in the supernatant of the infected cells. DNA from peripheral blood samples of the animals included in the study was isolated and genotyped with the EuroG MD bead Chip (44,779 single nucleotide-polymorphisms, SNPs). Linear mixed models were used to calculate the heritability (h2 ) estimates for each indicator of MDM performance, MAP load within MDMs and EREG, C3, Gal9, and NO-expression. After performing a genome-wide association study, the only phenotypes that showed SNPs with a significant association were the bacterial load within MDMs at 2 h (h2 = 0. 87) and 7 days (h2 = 0.83) p.i. A total of 6 SNPs, 5 candidate genes, and one microRNA on the Bos taurus chromosomes BTA2, BTA17, BTA18, and BTA21 were associated with MAP load at 2 h p.i. Overlap was seen in two SNPs associated with the log CFUs at 2 h and 7 d p.i. The identified SNPs had negative regression coefficients, and were, therefore, associated with a low bacterial load within MDMs. Some of the identified SNPs were located within QTLs previously associated with longevity, reproductive, and udder health traits. Some of the identified candidate genes; Oxysterol Binding Protein Like 6, Cysteine and Serine Rich Nuclear Protein 3, and the Coiled-Coil Domain Containing 92 regulate cellular cholesterol trafficking and efflux, apoptosis, and interferon production, respectively. Taken together, our results define a heritable and distinct immunogenetic profile in MAP-infected macrophages designed to limit bacterial load early after infection.

Abstract
In order to determine whether seasonal variations may influence the estrous cycle length (ECL), corpus luteum size (CLS), maximum area of CL (MACL), day of cycle with maximum area of CL (DCMACL), and pre-ovulatory follicles size (PFS), ten Criollo Limonero heifers were subjected to daily ultrasound ovary scanning throughout their estrous cycles during three seasons: hot-dry (HD), hot-humid (HH), and wind-rain (WR). The effect of season on ECL, MACL, DCMACL, and PFS was analyzed with an ANOVA (PROC GLM, SAS), whereas, for the effect of season on CLS, an ANOVA with repeated measures (PROC MIXED, SAS) was used. Results showed no effect (P > 0.05) of season on ECL, MACL, and DCMACL. However, size of PFS was larger (P < 0.02) during the WR season and the CLS tended (P < 0.09) to be lower during the HH. In conclusion, the relative stability of ECL, MACL, DCMACL, PFS, and CLS measures suggests no major seasonal variations which could imply adaptation capability of Criollo Limonero cattle to the tropical environment.

Abstract
Solute carrier family 11-member A1 (SLC11A1) gene encodes natural macrophage resistance-associated protein which regulates activity of macrophages against intracellular pathogens. The objective of this study was to study the polymorphism in the microsatellites present at 3′ untranslated region (UTR) of the SLC11A1 gene in 113 Zhongdian Yellow cattle (Bos taurus). Using DNA bi-directional sequencing, we detected seven alleles (GT10–16) for the first microsatellite (MS1), five alleles (GT12–16) for MS2, and four alleles (GT4–7) for MS3. MS3 is studied for the first time and revealed four novel variants (alleles GT4–7). Alleles GT12 (45.1%), GT13 (59.3%), and GT5 (85.4%) were the most frequent alleles at MS1, MS2, and MS3, respectively, Genotypes G12/12, G13/13, and G5/5 had the highest frequency 0.239, 0.540, and 0.743 at MS1, MS2, and MS3, respectively. Haplotypic data revealed that GT12/GT13 was the most frequent haplotype observed followed by GT12/14 haplotype. Three nucleotide variations were observed in MS1 and MS2. Comparative analysis of GT12/GT12 and GT13/GT13 genotype with other bovine genotypes showed significant difference (P > 0.05). Our results suggest that the homozygous genotypes GT12/GT12 and GT13/GT13 in Zhongdian Yellow cattle might be related to disease resistance. The findings reported in this study would be helpful in cattle breeding programs.

Abstract
To investigate the association between the incidence of human brucellosis (HB) and adverse pregnancy outcomes (APOs), a population-based, cross-sectional aggregate data study was conducted in Israel between 2010 and 2014. HB-endemic localities were matched by ethnicity, population size and socioeconomic status to localities with a low incidence of HB. We compared APO rates in high-incidence vs low-incidence localities. The primary outcome was intrauterine fetal demise (IUFD). Secondary outcomes were premature birth (less than 37 weeks), early or threatened labour and poor fetal growth. APOs are expressed as events per 1,000 live or dead births. Eleven high-incidence localities, all Arab villages or cities, were matched to 11 low-incidence localities. Localities were well-matched with regard to the matching criteria, fertility indices, health insurance access and education, but were imbalanced geographically. All defined APOs occurred significantly more frequently in the high-incidence localities. The associations translated to an absolute increase of 3.6 cases of IUFD (95% CI 1.6-5.3), 11.7 preterm births (4.8-18.3), 6.6 cases of early or threatened labour (2.2-10.9) and 7 cases of poor fetal growth (3-10.8), per 10,000 live or dead births. Owing to a geographic imbalance between high- and low-incidence localities, we conducted an analysis restricted to Southern localities of Arab Bedouins showing a significant association between yearly HB incidence and IUFD incidence, odds ratio 1.05 (1.03-1.06). HB incidence is epidemiologically linked to serious pregnancy complications. Early detection of infection through active surveillance during pregnancy followed by appropriate treatment should be evaluated as additional public heath strategy in endemic settings.

Abstract
Short tandem repeats (STRs), or microsatellites, are genetic variants with repetitive 2–6 base pair motifs in many mammalian genomes. Using high-throughput sequencing and experimental validations, we systematically profiled STRs in five Holsteins. We identified a total of 60,106 microsatellites and generated the first high-resolution STR map, representing a substantial pool of polymorphism in dairy cattle. We observed significant STRs overlap with functional genes and quantitative trait loci (QTL). We performed evolutionary and population genetic analyses using over 20,000 common dinucleotide STRs. Besides corroborating the well-established positive correlation between allele size and variance in allele size, these analyses also identified dozens of outlier STRs based on two anomalous relationships that counter expected characteristics of neutral evolution. And one STR locus overlaps with a significant region of a summary statistic designed to detect STR-related selection. Additionally, our results showed that only 57.1% of STRs located within SNP-based linkage disequilibrium (LD) blocks whereas the other 42.9% were out of blocks. Therefore, a substantial number of STRs are not tagged by SNPs in the cattle genome, likely due to STR's distinct mutation mechanism and elevated polymorphism. This study provides the foundation for future STR-based studies of cattle genome evolution and selection.

Abstract
Activation of innate immunity initiates various cascades of reactions that largely contribute to defense against physical, microbial or chemical damage, prompt for damage repair and removal of causative organisms as well as restoration of tissue homeostasis. Genetic polymorphism in innate immune genes plays prominent role in disease resistance capabilities in various breeds of cattle and buffalo. Here we studied single nucleotide variations (SNP/SNV) and haplotype structure in innate immune genes viz CHGA, CHGB, CHGC, NRAMP1, NRAMP2, DEFB1, BNBD4, BNBD5, TAP and LAP in Gir cattle and Murrah buffalo. Targeted sequencing of exonic regions of these genes was performed by Ion Torrent PGM sequencing platform. The sequence reads obtained corresponding to coding regions of these genes were mapped to reference genome of cattle BosTau7 by BWA program using genome analysis tool kit (GATK). Further variant analysis by Unified Genotyper revealed 54 and 224 SNPs in Gir and Murrah respectively and also 32 SNVs was identified. Among these SNPs 43, 36, 11,32,81,21 and 22 variations were in CHGA, CHGB, CHGC, NRAMP1, NRAMP2, DEFB1 and TAP genes respectively. Among these identified 278 SNPs, 24 were found to be reported in the dbSNP database. Variant analysis was followed by structure formation of haplotypes based on multiple SNPs using SAS software revealed a large number of haplotypes. The SNP discovery in innate immune genes in cattle and buffalo breeds of India would advance our understanding of role of these genes in determining the disease resistance/susceptibility in Indian breeds. The identified SNPs and haplotype data would also provide a wealth of sequence information for conservation studies, selective breeding and designing future strategies for identifying disease associations involving samples from distinct populations. Sequencing of exonic regions of 10 selected innate immune genes, 895.60 Mb data was generated. Variant analysis using GATK pipeline revealed 278 SNPs, 32 SNVs and from these 24 were found to be reported. 43, 36 and 11 SNPs were observed in chromagranin genes viz. CHGA, CHGB and CHGC respectively. 32 and 81 SNPs were identified in NRAMP genes viz. NRAMP1 and NRAMP2 respectively. 21 and 22 SNPs were observed in β-defensin genes viz. DEFB1 and TAP respectively.

Abstract
Johne's disease or paratuberculosis is a chronic, progressive intestinal disease of ruminants caused by Mycobacterium avium subsp. paratuberculosis (MAP). One of the genes that have been targeted with regard to resistance or sensitivity to paratuberculosis is the SLC11A1 (solute carrier family 11 member A1). Here we extend our previous work to the sequence and structure analysis of the caprine SLC11A1 gene and we assess the functional impact of the most frequent polymorphisms of the 3' UTR region of the SLC11A1 gene to its expression in goat macrophages exposed in vitro to MAP. The role of these polymorphisms in primary immune response is also investigated with connection to gene expression of two interleukins (IL), one of which pro (IL-1a), and the other anti-inflammatory (IL-10). In order to assess gene response, quantitative detection of the SLC11A1, IL-10 and IL1a mRNA was performed by real time PCR before, and at 1, 3 and 24h after exposure of primary cultures of peripheral blood monocyte-derived macrophages to MAP, collected from 54 goats of the Greek native goat breed. Sequence analysis of the 3' UTR end of the caprine SLC11A1 gene determined its full length to be 522 bases. Structure analysis confirmed the presence of two microsatellites consisted of a variable number of guanine-thymine repeats (regions A and B). The homozygous B7 genotype [B(GTn)7/7] was associated at a statistically significant level with increased expression of the SLC11A1 and IL-1α genes indicating increased in vitro responsiveness and therefore resistance of mononuclear derived macrophages to MAP infection.

Abstract
Polymorphisms in microsatellites at the 3' untranslated region (3'UTR) of the SLC11A1 (solute carrier family 11 member A1) gene have been associated with natural resistance to Brucella abortus and Mycobacterium bovis infection in livestock species. Here, we carried out an individual genetic analysis of the two microsatellites present at the 3'UTR SLC11A1 gene in 254 Bos taurus purebred, 125 B. indicus purebred and 54 B. taurus × B. indicus crossbred cattle. The genotyping by capillary electrophoresis showed the presence of four alleles (157, 159, 161 and 163) for the first microsatellite (MS1) and six alleles (175, 177, 179, 181, 183 and 185) for the second microsatellite (MS2). The alleles 159 and 175 were the most frequent in all breeds analyzed. B. taurus showed the most homogeneous haplotype and genotype for both microsatellites, whereas B. indicus showed the most heterogeneous haplotype and genotype. Two novel variants (alleles 161 and 163) within the MS1 are reported as well as novel variants in MS2 in Holstein breed. The knowledge of the polymorphisms distribution in both microsatellites at the 3'UTR of the SLC11A1 gene in cattle breeds is useful for future experimental design to evaluate the association between reported genotypes and natural resistance to pathogens infection.

Abstract
Brucella abortus is a Gram negative facultative intracellular pathogen of cattle, and an important zoonosis in humans worldwide. Previous studies have shown that dendritic cells (DC) from humans and mice are highly permissive for Brucella survival and proliferation. Impairment of DC activation and maturation by Brucella infection has also been reported in these two species. The aim of this study was to characterize infection of bovine DC with B. abortus. Monocyte-derived DC (mdDC) were cultured from bovine peripheral blood mononuclear cells (PBMC) using the recombinant bovine cytokines IL-4 and GM-CSF. The resulting mdDC were DEC205(+), MHC class II(hi). Approximately 70% of the cultured cells were DEC205(+), MHC II(+). MdDC were infected with B. abortus strain 2308 at an MOI of 1 and 100. Parallel infection experiments were performed in monocyte derived macrophages (mdM) isolated from the same subjects. Bacteria were successfully killed by mdDC by 24 hours post infection (PI) with high and low dose of B. abortus, bacteria persisted in mdM infected with a high dose. Expression of IL-1b, IL-6, IL-10, IL-12p40, IFNγ, iNOS and TNFα in B. abortus infected and LPS stimulated mdDC at 6 and 24 hours PI were evaluated using RT-qPCR. At 6 hours PI all transcripts were increased over control cells and significantly less IL-10, IL-12p40, and IFNγ were expressed in mdDC infected with B. abortus compared to LPS stimulation. Evaluation of mdDC cultures by flow cytometry was performed. Flow cytometric analysis of infected and LPS stimulated mdDC 24 hours PI showed expression of CD80 and CD86 was impaired in two of the three animals analyzed. MHC class II expression was equivocal between the groups. From these results we conclude that cultured bovine mdDC are not permissive for intracellular proliferation of B. abortus, and infected mdDC exhibit some signs of maturational and activational impairment.

Abstract
The resistance/susceptibility of selected cattle breeds to brucellosis was evaluated in an F1 population generated by crossing animals classified as resistant (R) and susceptible (S) (R x R, R x S, S x R, S x S) based on challenges in vitro and in vivo. The association between single nucleotide polymorphisms identified in the coding region of the Slc11a1 gene and resistance/susceptibility was estimated. The trait resistance or susceptibility to brucellosis, evaluated by a challenge in vitro, showed a high heritable component in terms of additive genetic variance (h(2) = 0.54 ± 0.11). In addition, there was a significant association (p < 0.05) between the control of bacterial survival and two polymorphisms (a 3'UTR and SNP4 located in exon 10). The antibody response of animals classified as resistant to infection by Brucella abortus differed significantly (p < 0.05) from that of susceptible animals. However, there was no significant association between single nucleotide polymorphisms located in the Slc11a1 gene and the antibody response stimulated by a challenge in vivo.

Abstract
SLC11A1 (solute carrier family 11 member A1) protein is located on the phagolysosome membrane of macrophages and participates in bacterial killing. Here we have extended our previous work on the investigation of the potential association of polymorphisms of the 3'untranslated region (UTR) of SLC11A1 gene with test-positivity of goats to Mycobacterium avium subsp. paratuberculosis (MAP). Blood, serum and faeces were collected from 223 adult goats, from nine goat farms from Greece with a long-term record of paratuberculosis but no vaccination or tuberculin testing. The samples were subjected to sequence and structure analysis of the SLC11A1 gene and were evaluated by ELISA, culture and real time polymerase chain reaction. The 3'UTR region of the targeted gene revealed 2 microsatellites consisting of a variable number of guanine-thymine repeats named regions A and B. Statistically significant association was recorded between genotypes of region B and ELISA results, whereas the presence of B(7) allele was found to contribute to ELISA negativity. The comparison of the SLC11A1 mRNA level pre- and post-exposure to MAP shows elevated gene expression especially at the 3-h time point, in all macrophages tested regardless of their genotype. Unfortunately the latter could not be linked at a statistically significant level with any of the targeted genetic polymorphisms separately. In conclusion it can be stated that the evidence reported here provide the first indications on the association of B genotypes of the SLC11A1 gene and the detection of MAP-specific antibody by ELISA in goats.

Prev Vet Med 2009; 91:189-96. [PMID: 19525022 DOI: 10.1016/j.prevetmed.2009.05.020] [Citation(s) in RCA: 65] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2008] [Revised: 05/12/2009] [Accepted: 05/14/2009] [Indexed: 11/25/2022]
Abstract
Paratuberculosis (Johne's disease) imposes a significant problem to the world dairy and beef industries and today is considered a potential zoonosis. The disease is caused by Mycobacterium avium subsp. paratuberculosis and is characterized by progressive weight loss and profuse diarrhoea. Susceptibility to infection is suspected to have a genetic component, and moderated values for heritability of infection have been reported. Interferon gamma is an inducible cytokine with a crucial role in the innate host response to intracellular bacteria. Toll-like receptors are trans-membrane structures responsible for coordination of innate and adaptive immune responses. The solute carrier family 11 member 1 (SLC11A1, formerly NRAMP1) gene plays an important role in innate immunity, preventing bacterial growth in macrophages during the initial stages of infection. The objective of this candidate gene case-control study was to characterize the distribution of polymorphisms in three candidate genes related to the immune function; interferon gamma (BoIFNG), toll-like receptor 4 (TLR4), and SLC11A1 genes and to test their role as potential risk factors for paratuberculosis infection in cattle. The statistical analysis demonstrated significant differences in allelic frequencies between cases and controls for BoIFNG-SNP(1)2781 and SLC11A1 microsatellites, indicating a significant association between infection and variant alleles. In the analysis of genotypes, a significant association was also found between infection status and BoIFNG-SNP(1)2781 and SLC11A1-275-279-281 microsatellites. However, when variables such as breed and age were included in the multivariate logistic regression analysis, a tendency toward statistical significance for the effect of polymorphisms in the odds of infection was only found for alleles SLC11A1-275 and 279.
