Phylogenetic relationships among 50 Phytophthora species and between Phytophthora and other oomycetes were examined on the basis of the ITS sequences of genomic rDNA. Phytophthora grouped with Pythium, Peronospora, and Halophytophthora, distant from genera in the Saprolegniales. Albugo was intermediate between these two groups. Unlike Pythium, Phytophthora was essentially monophyletic, all but ...

Principally, plants grown in soilless culture may be attacked by the same pests and diseases as cultivated traditionally in soil. The most destructive phytopathogens are fungi, such as Phythium, Phytophthora and Fusarium, followed by viruses, bacteria and nematodes. We investigated effect of carbon nanotube filters on disease management of soilless culture. Tomato seedlings transplant in plasti...

The oomycete Pythium periplocum is an aggressive mycoparasite of a number of plant pathogenic fungi and oomycetes and therefore has potential as a biological control agent. Here, we report the first draft genome sequence of P. periplocum, which comprises 35.89 Mb. It contains 1,043 scaffolds and 14,399 predicted protein-coding genes.

The authors investigated mycoflora developing on the eggs of three species of the percid fish. At total of 45 aquatic fungi (including 26 as parasites or necrotrophs) were noted. Pythium capillosum is a new record for Poland. The highest number of fungus species developed on eggs of all percids in water from the Biala river, which had the highest content of biogenic compounds.

pythium species are cosmopolitan, fungus-like oomycotes which may cause diseases in plants, animals and even human beings. some of the species, however, are saprophytes and also well-proven biological control agents of plant pathogenic fungi. since 1968, when the first pythium species was reported from iran, ca 44 species, two varieties, and five groups of this genus have been reported from dif...

Sir, The interesting article by Jain et al. describes the resistance pattern of GABHS (group-A beta-hemolytic streptococci) in northern India.[1] The article may be of immense interest to all clinicians. The authors mention in the abstract section that the current resistance pattern of GABHS has not been discussed in India, which is incorrect. A thorough search of literature reveals that Lloyd ...

A retrospective review of medical records for 32 patients with invasive group C streptococcus (GCS) or group G streptococcus (GGS) infections was performed. MICs and minimum bactericidal concentrations (MBCs) of penicillin, erythromycin, and vancomycin for all isolates were obtained. Tolerance of vancomycin, defined as an MBC 32 or more times higher than the MIC, was exhibited by 18 GGS isolate...
