Growth measurement of Escherichia coli by differential scanning calorimetry
Using differential scanning calorimetry (DSC) and plate count (PC), growth of Escherichia coli was measured in four initial E. coli cell concentrations cultured in tryptic soy broth (TSB) at 35°C. The calorimeter measured the energy released and/or absorbed by E. coli cells during growth and expressed it as thermograms. The resulting thermograms accurately reflected cell growth and activity, and exhibited a close...

Status of root-knot nematode (Meloidogyne species) disease in vegetable crops of some districts of central plain region of Chhattisgarh State, India
The root-knot nematodes (Meloidogyne species) are economically important pathogens, especially infesting vegetable crops. In the tropics and subtropics, Meloidogyne incognita causes an estimated yield loss of 5 to 43% in vegetable crops. In the present study, root-knot nematode disease was surveyed in various vegetable crops in the central plain region of Chhattisgarh State. Roots and rhizosphere soil samples were...

Bioprocessing of sugarcane factory waste to production of Itaconic acid
This paper aimed at advances in industrial biotechnology over potential opportunities for economic utilization of agro-industrial residues sugarcane bagasse. Sugarcane bagasse, which is a complex material, is the major by-product of the sugarcane industry. The present work has been taken up with a view of exploring the possibilities of using agriculture by products as a source for the production of itaconic acid from...

Antifungal resistance and herbal sensitivity of oral Candida isolates from HIV-infected patients in a rural community in Western Uttar Pradesh, India
Drug-resistant Candida species in HIV-infected patients are the result of the selective pressure of currently used azoles. In the course of screening for active plant products against drug-resistant Candida species, we paid special attention on the effects of commonly available herbal plants. A total of 123 oral Candida isolates which were previously isolated from 172 HIV-infected patients were included in this study....

Parasites in synanthropic rodents in municipality of the Northwest region of the State of Paraná, Brazil
The aim of this study was to identify the presence of different parasites in synanthropic rodents captured in the urban and peri-urban area in the city of Umuarama, Paraná (PR). The rodents were euthanized for measurement and collection of feces and ectoparasites. Specific identification keys were used for the ectoparasitological analysis and the technique by Hoffman et al. (1934) was used for the...

Studies on Conidiomata developmental morphology of Pestalotiopsis disseminata
This study shows the conidiomatal development of Pestalotiopsis disseminata (Thuen.) Stey., using light and transmission electron microscope. Light microscopic study showed the presence of non-ostiolate pycnidial conidiomata in culture, whereas it is known to produce only acervular conidiomata on leaves. Interestingly, the fungus showed the ultrastructure of the conidial wall in the coloured cells as well as the basal...

Determination of morphometric, biochemical and genetic variation in Sclerotium delphinii isolates
Variability among four isolates of Sclerotium delphinii isolated from infected diseased Khirni (Manilkara hexandra); chafa (Plumeria rubra acutifolia) and Jackfruit (Artocapus heterophyllus) plants of Western Maharashtra region of India were studied. This is the first report on presence of S. delphinii species in India. These isolates varied in colony morphology, mycelial growth rate, sclerotia formation period,...

Hypocrea/Trichoderma viridescens ITV43 with potential for biocontrol of Moniliophthora roreri Cif & Par, Phytophthora megasperma and Phytophthora capsici
A Hypocrea/Trichoderma strain was isolated from cacao (Theobroma cacao L.) pods from a cacao plantation in Huimanguillo, Tabasco, Mexico. The strain was identified as H./T. viridescens ITV43 by its morphological characteristics and DNA sequence analysis of ITS1-5.8s-ITS2 and was tested against Moniliophthora roreri Cif & Par and Phytophthora strains by confrontation experiments. The biocontrol of H./T. viridescens...

Effect of citron by-product fermented with beneficial bacteria as a functional feed additive for Korean native steers
This study was conducted to develop a functional feed additive, citron (Citrus junos Sieb. ex Tanaka) probiotics (CPB) for beef cattle, using citrus junos by-product (CJ) with probiotics. A two-step fermentation process was developed for the production of CPB and the effects of CPB on growth performance, immune status, carcass characteristics and fatty acid profile in Korean native (Hanwoo) steers were investigated....

Massive mortality associated with Streptococcus iniae infection in cage-cultured red drum (Sciaenops ocellatus) in Eastern China
In August, 2011, an enzootic disease characterized by hemorrhage throughout body surface, enlarged spleen and kidney occurred in cage farmed red drum fish, in Dongtou, Zhejiang of China. The diseased fish weighed between 100 to 200 g, and the cumulative mortality within 60 days was higher than 70%. Several bacterial isolates that exhibited the same phenotypic traits and biochemical characteristics were isolated from the...

Associations of cytomegalovirus with type I diabetes mellitus among children in Khartoum State
Cytomegalovirus is one of the most common microorganisms that cause opportunistic infection that complicate the clinical care and progress of immunecompromised patients. The virus can cause severe diseases with multiple complications including type I diabetes mellitus. The present study is a case control study aimed at determining cytomegalovirus among type I diabetic mellitus in Sudanese children. Sera of eighty one...

Modeling of ultraviolet (UV) radiation under a large pilot-scale designed for wastewater disinfection and inactivation of selected bacteria of Pseudomonas aeruginosa in a laboratory UV device
The aim of this paper was to propose a modeling system of water ultraviolet (UV) disinfection. Results reveal that application of the model of Chick-Watson in its original form or modified are not representative of the kinetics of disinfection. For this reason, the application of a new kinetic model of Collins-Selleck in UV inactivation of Pseudomonas aeruginosa in secondary wastewater appeared to be the best applied...
