| ABSTRACT: We aimed to genotype the South American clinical isolates of Pythium insidiosum using the single nucleotide polymorphisms (SNP) of the ribosomal DNA sequences (rDNA). Previously, an SNP-based multiplex-PCR was able to distinguish three different clades of P. insidiosum isolates. Thus, we used this assay to evaluate South American clinical isolates of P. insidiosum (n=32), standard strains from Costa Rica (n=4), Thailand (n=3), Japan (n=1), and India (n=1), a standard strain of Pythium aphanidermatum, and Brazilian environmental isolates of Pythium torulosum, Pythium rhizo-oryzae and Pythium pachycaule voucher (n=3). It was possible to allocate each American P. insidiosum isolate to clade I, the isolates of India, Japan, and Thailand to clade II,... |

| ABSTRACT We report a case of intestinal intussusception secondary to enteritis caused by Pythium insidiosum infection in a 1-year-old mixed breed bitch that died after a 30-day history of bloody diarrhea, anorexia, weight loss, listlessness, dehydration, and pale mucous membranes. Necropsy revealed two areas of intussusception, one jejunum-jejunal and one ileum-cecum-colic. The first intussusception showed slight congestion of the intestinal loop, which was resolved by manual traction, while the second intussusception exhibited thickening, irregular yellow spots, and transmural congestion. Histologically, the jejunum-jejunal segment had ischemic lesions secondary and ileum-cecum-colic intussusception there was also necrotizing, pyogranulomatous enteritis... |

| Also known as phycomycoses, pythiosis and zygomycosis are mycotic diseases with very similar morphological and histopathological features, and occur in skin, subcutaneous tissue, GI tract and lungs, mainly in horses. The etiological agents are soil and vegetation saprophytes present in swamps. Horses acquire the infection by remaining in these areas, in contact with the soil, favoring the occurrence of infected granulomatous lesions mainly in the distal portion of the limbs, ventral region of thea bdomen, chest and neck, with severe pruritus, ulceration, and viscous and abundant serosanguineous secretion. Several methods are used to treat these mycoses, surgical excision associated with amphotericin B being the most important. However, new adjuvant... |
