| unilateral orchitis and epididymitis caused by salmonella enterica subspecies diarizonae infection in a ram. | a case of unilateral suppurative epididymo-orchitis associated with salmonella enterica subsp. diarizonae serovar 61:k:1,5,(7) infection is described in a 2-year-old ram. gross lesions were characterized by severe enlargement of the scrotal contents, fibrous adhesions between testicular layers, coexistence of epididymal abscesses and foci of fibrinous exudate, and testicular atrophy. microscopically, testicular and epididymal microabscesses and diffuse inflammatory infiltrates with abundant macr ... | 2007 | 17402617 |
| presence of escherichia coli o157, salmonella spp., and listeria monocytogenes in raw ovine milk destined for cheese production and evaluation of the equivalence between the analytical methods applied. | italy is one of the main producers and exporters of cheese made from unpasteurized sheep milk. since raw milk and its derived products are known sources of human infections, cheese produced from raw sheep milk could pose a microbiological threat to public health. hence, the objectives of the study were: to characterize the potential risk of the presence of pathogens escherichia coli o157, listeria monocytogenes, and salmonella in raw ovine milk destined for cheese production obtained from all th ... | 2016 | 27607835 |
