Giardia duodenalis isolates recovered from humans and dogs living in the same locality in a remote tea-growing community of northeast India were characterized at 3 different loci; the SSU-rDNA, elongation factor 1-alpha (ef1-alpha) and triose phosphate isomerase (tpi) gene. Phylogenetic analysis of the SSU-rDNA and efl-alpha genes provided poor genetic resolution of the isolates within various ...

Botryosphaeria rhodina (anamorph Lasiodiplodia theobromae) is a common endophyte and opportunistic pathogen on more than 500 tree species in the tropics and subtropics. During routine disease surveys of plantations in Australia and Venezuela several isolates differing from L. theobromae were identified and subsequently characterized based upon morphology and ITS and EF1-alpha nucleotide sequenc...

Small subunit ribosomal DNA (SSU-rDNA), glutamate dehydrogenase (gdh), beta-giardin, triosephosphate isomerase (tpi), and elongation factor 1-alpha (ef1-alpha) genes are useful genetic markers for genotypic analysis of the intestinal protozoan, Giardia duodenalis (syn. G. lamblia, G. intestinalis), the cause of enteric disease in humans. To quantitatively compare the discriminatory power of the...

We study the allocation of indivisible goods that form an undirected graph and quantify loss fairness when we impose a constraint each agent must receive connected subgraph. Our focus is on well-studied notions including envy-freeness maximin share fairness. introduce price connectivity to capture largest gap between graph-specific unconstrained share, derive bounds this quantity which are tigh...

Poriella subacida gen. & comb. nov., previously known as Perenniporia subacida, which causes white rot, has been documented in temperate and tropical forests. Specimens from Asia, North America, Europe were examined, including the type specimen of Polylorus subacidus. Sequences ITS1-5.8S-ITS2 region, 28S rDNA, mitochondrial rDNA small subunit (mtSSU), gene encoding translation elongation fa...

O quipá (Tacinga inamoena) é uma cactácea nativa da Caatinga brasileira. Estudos sobre doenças nessa espécie são inexistentes, no entanto, manchas marrons, de etiologia até então desconhecida, tem sido observada em cladódios estado Alagoas. Dados preliminares indicam que fungos do gênero Fusarium podem ser responsáveis pela doença, contudo, esses dados precisam confirmados utilizando ferramenta...
