Thermal physiology of entomopathogenic nematodes (EPN) is a critical aspect of field performance and fitness. Thermal limits for survival and activity, and the ability of these limits to adjust (i.e., show phenotypic flexibility) depending on recent thermal history, are generally poorly established, especially for non-model nematode species. Here we report the acute thermal limits for survival,...

Klebsiella pneumoniae carbapenemase (KPC) is a carbapenemase increasingly reported worldwide in Enterobacteriaceae. The aim of this study was to analyze the virulence of several KPC-2-producing K. pneumoniae isolates. The studied strains were (i) five KPC-2 clinical strains from different geographical origins, belonging to different ST-types and possessing plasmids of different incompatibility ...

Sir,?The translation of the article of Drs. G. Di Cristana and G. Caronia in the May 15th number of the Journal of Tropical Medicine, reporting the successful treatment of the Mediterranean form of kala-azar by means of tartar emetic intravenously, lias just reached India. I, therefore, write to place on record the fact that I had previously commenced precisely similar treatment of the Indian f...

Social bacterial interactions are considered essential in numerous infectious diseases, particularly in wounds. Foot ulcers are a common complication in diabetic patients and these ulcers become frequently infected. This infection is usually polymicrobial promoting cell-to-cell communications. Staphylococcus aureus is the most prevalent pathogen isolated. Its association with Helcococcus kunzii...

Background: There are several plant extractions which are being used for mosquito control. The aim of this study was to evaluate the efficacy of Olea vera, Linum usitatissimum and Piper nigera against Anopheles stephensi and Aedes aegypti under laboratory conditions. Methods: These tests were carried out using WHO recommended bioassay method for adult mosquitoes. Results: The extracts from blac...

fumigant toxicity of various doses of essential oils (185.2, 370.4, 555.5, 740.7, 925.4, 1111.1, and 1296.3 µl/l water) from five officinal plants, including rosemary (rosmarinus officinalis), lavender (lavandula vera), fennel (foeniculum vulgare), tarragon (artemisia dracunculus)and summer savory (satureja hortensis)on two stored products pests, cowpea weevil (callosobruchus maculatus) and red...

Survival after freezing was measured for seeds and germinants of four seedlots each of interior spruce (Picea glauca x engelmannii complex), lodgepole pine (Pinus contorta Dougl. ex Loud.), Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) and western red cedar (Thuja plicata Donn ex D. Donn). Effects of eight seed treatments on post-freezing survival of seeds and germinants were tested: dry, ...
