OBJECTIVES To investigate and characterize Mycobacterium avium subspecies paratuberculosis (MAP) in patients with Crohn's disease, attendants of animals with suspected infection, and healthy humans, using multiple diagnostic tests. METHODS A total of 119 samples (35 stool, 76 serum, three blood clots, and five biopsies) were collected from five patients with Crohn's disease, eight attendants ...

Population structure and relationship information among goats is critical for genetic improvement, utilization, conservation. This study explored population level of introgression four goat breeds in Kenya: the indigenous Galla (n = 12) three imported breeds, Alpine 29), Toggenburg 31), Saanen 24). Genetic diversity was analyzed using indices (polymorphic SNPs, mean allele frequency, observed e...

OBJECTIVES To describe levels of risky sexual behaviour, HIV testing and HIV knowledge among men and women in Guatemala by ethnic group and to identify adjusted associations between ethnicity and these outcomes. DESIGN Data on 16,205 women aged 15-49 and 6822 men aged 15-59 from the 2008-2009 Encuesta Nacional de Salud Materno Infantil were used to describe ethnic group differences in sexual ...

The present investigation was carried out on 1,070 local goats named as Udgiri goat in 242 villages from Marathwada and western Maharashtra during 2018 to 2021. average body weight of adult male is 42.77±3.94 kg while female 32.98±3.44 highest than any other recognized indigenous breeds Maharashtra. length 76.53±3.53 cm, height at withers 74.65±1.65 chest girth 74.46±1.72 paunch 73.54±3.88 tail...

The main objective of the current study was to obtain preliminary results on genetic polymorhism of A and C variants at the CSN2 locus in indigenous Romanian goat (Banat White, Carpatina) breeds using a rapid and efficient genotyping method, TaqMan assay (Applied Biosystems, USA). Hair follicle samples were taken from 73 Banat White and 82 Carpatina purebred goats from Arad, Caras-Severin and T...

We looked for novel genetic variations within the Six6 gene by PCR-SSCP, DNA sequencing and forced RFLP-PCR and estimated their associations with production traits in 2132 goats of eight indigenous Chinese breeds. A novel single nucleotide polymorphism (NM_001104993.1: g.232T>C) within the goat Six6 gene was identified. The frequencies of allele "C" varied from 0.8621 to 1.000, which were...

Detecting signatures of selection can provide a new insight into the mechanism of contemporary breeding and artificial selection and further reveal the causal genes associated to the phenotypic variation. However, the signatures of selection on genes entailing for profitable traits between Chinese commercial and indigenous goats have been poorly interpreted. We noticed footprints of positive se...
