| human and bovine viruses and bacteria at three great lakes beaches: environmental variable associations and health risk. | waterborne pathogens were measured at three beaches in lake michigan, environmental factors for predicting pathogen concentrations were identified, and the risk of swimmer infection and illness was estimated. waterborne pathogens were detected in 96% of samples collected at three lake michigan beaches in summer, 2010. samples were quantified for 22 pathogens in four microbial categories (human viruses, bovine viruses, protozoa, and pathogenic bacteria). all beaches had detections of human and bo ... | 2016 | 26720156 |
| development and performance evaluation of calf diarrhea pathogen nucleic acid purification and detection workflow. | calf diarrhea (scours) is a primary cause of illness and death in young calves. significant economic losses associated with this disease include morbidity, mortality, and direct cost of treatment. multiple pathogens are responsible for infectious diarrhea, including, but not limited to, bovine coronavirus (bcv), bovine rotavirus a (brv), and cryptosporidium spp. identification and isolation of carrier calves are essential for disease management. texas veterinary medical diagnostic laboratory cur ... | 2012 | 22914823 |
| g and p genotype profiles of rotavirus a field strains circulating in beef and dairy cattle herds in brazil, 2006-2015. | the aim of this retrospective study was to use rt-pcr and nucleotide sequencing analysis to determine the g (vp7 gene) and p (vp4 gene) genotypes of 155 brazilian bovine rotavirus a (rva) wild-type strains detected in diarrheic calves from all brazilian geographical regions from 2006 to 2015. the rva strains evaluated belonged to the g6, g10, p[5], and p[11] genotypes. the g6p[5] genotype was prevalent (65.5%; p < 0.05) in beef, and the g10p[11] (38.4%) and g6p[11] (30.8%) genotypes were more pr ... | 2019 | 31174706 |
| genotype constellation of a rotavirus a field strain with an uncommon g8p[11] genotype combination in a rotavirus-vaccinated dairy cattle herd. | in this report we describe the genotype constellation of a bovine rotavirus a (rva) strain with an uncommon g8p[11] genotype combination. the rva/cow-wt/bra/y136/2017/g8p[11] strain was classified as g8-p[11]-i2-r5-c2-m2-a3-n2-t9-e2-h3. phylogenetic analysis based on the vp7 gene showed that the y136 strain and a human g8p[1] strain comprise a putative new (vii) lineage for the g8 genotype. in addition, two other genotypes, r5 (vp1) and t9 (nsp3), were identified in the constellation of y136 tha ... | 2020 | 32472289 |
