Bacterial community in two subtropical fishponds in São Paulo, Brazil
The knowledge concerning fishpond microorganisms is important considering the aquatic microbial ecology and water quality. In this study, we compared the bacterial communities present in freshwaters of two fish farm ponds from Brazil, one used as water reservoir (P1) and the other with conditions of high nutrient load (P4). The aim of this study was to identify and compare the bacterial population in two fishponds...

Physical, chemical and biological aspects of the urine of sows in a certificated swine reproduction farm in the city of Toledo, Paraná, Brazil
Urinary tract infection in sows is among the main reproduction problems because of its influences on productivity of the herd, affecting mainly the general health of sows and has considerable increase in the replacement rate. Thus, it is considered as the most important endemic disease in the sow in the production phase. The aim of this study was to determine the physical, chemical and microbiological aspects of the...

Bacterial population dynamics in a crude oil polluted soil undergoing bioremediation in a screen house
A study was carried out in a screen house to determine the bacterial population dynamics in a crude oil soil undergoing bioremediation. The agricultural soil samples were polluted with different concentrations (5, 8 and 11%) of crude oil. Physiochemical and microbiological analyses were carried out on the polluted and unpolluted soil samples at various intervals beginning from two weeks after the pollution of the soil...

Antimicrobial activities of four perylenediimides
Increasing resistance to several antibiotics has crucial importance. Many researchers are trying to discover alternative methods or agents to develop antimicrobial effectiveness. In this study, antimicrobial activities of four diverse synthesized perylene diimides were tested, because they are well known dyes and pigments for useful various applications and also antimicrobial activities. These perylene diimides were...

Biodegradation potentials of bacterial isolates from petroleum storage facilities within the Kumasi Metropolitan area
High on the table of environmental discussions worldwide today is the problems of petroleum hydrocarbon contamination. This research focused on screening for the potentials of five bacterial isolates in utilizing the following hydrocarbon substrates [gasoline, diesel and kerosene (2.0v/v) in Bergs Mineral Salt Medium (BMSM)]. The effects of different nutrients supplementation on biodegradation indices were assessed. The...

Statistical screening for the chitinase production by nematophagous fungi from Monacrosporium genu
Several chitinases with nematicidal action of these fungi have been identified in recent years, however, little is known about which nutritional factors from the culture medium are significant for its mass production. The aim of this study was to perform the statistical screening of the components of the culture medium for chitinase production by nematophagous fungi, Monacrosporium sinense (SF53) and Monacrosporium...

Genetic relationship between clinical and environmental Vibrio cholerae isolates in Tanzania: A comparison using repetitive extragenic palindromic (REP) and enterobacterial repetitive intergenic consensus (ERIC) fingerprinting approach
The bacterium causing cholera, Vibrio cholerae, is a marine organism and coastal waters are important reservoirs of the organism. There are more than 200 serogroups of V. cholerae, of which serogroups O1 and O139 are known to be the causative agent of the cholera. The main virulent factor in V. cholerae is cholera toxin gene (ctx) that is found from the epidemic O1 and O139 strains, but may also be found in some strains...

Application of arbuscular mycorrhiza for managing root-knot disease in tomato (Lycopersicon esculentum) under glass-house conditions in Pantnagar, India
Root-knot disease caused by Meloidogyne spp. poses a worldwide threat to agriculture as well as environment due to excess use of chemical nematicides for its management. Recently, arbuscular mycorrhizal fungi (AMF) have achieved importance as biocontrol agent for the managements of root-knot disease. In this aspect, the present study was focused on the effect of AMF (Glomus intraradices) against root-knot disease of...

Effect of nitrogen supply on rhizobacterial propagation and soil enzyme activity in pot soil cultivated with Phytophthora infestans-infected potato plants
We previously demonstrated that providing potato plants with an optimum nitrogen supply (in the form of urea; 135 kg hm-2) produces high crop yields and increased resistance to late blight. However, the mechanisms underlying these responses have not been well characterized. In this study, we examined the effects of various levels of nitrogen fertilization (four levels: N1, 45 kg hm-2, N2: 90 kg hm-2, N3: 135 kg hm-2 and...

Seroprevalence of human Anaplasma phagocytophilum in Bursa Province, Turkey
The aim of this study was to determine the seroprevalence of Anaplasma phagocytophilum infections in rural areas of Bursa Province, where vector ticks and blood-sucking flies are commonly found. In total, 150 blood samples were collected from people living in four different locations where vector ticks are common, and 45 blood samples were collected from people living in non-tick-infested areas. Giemsa-stained blood...

Screening of maize inbred lines under artificial epiphytotic conditions for Turcicum leaf blight (Excerohilum turcicum)
A study on reaction of ten inbred lines of maize to northern leaf blight mainly caused by Exserohilum turcicum (Pass) Leonard and Suggs, was conducted under artificial epiphytotics conditions in green house. Among 10 inbred lines evaluated, three were found moderately resistant viz, NAI-113, NAI-152 and NAI-137, five lines moderately susceptible viz, NAI-123, NAI-142, NAI-143, NAI-147 and NAI-116, and the rest two, W3...
