Abstract: This paper examines the attitude of students towards Biology and Chemistry. There was also a focus on the parental involvement. This research was set out find out how parental involvement influences students’ attitude towards, and performance in the two science subjects. An attitude questionnaire developed and standardized by the researcher was used. It’s split-half reliability coefficient yielded 0.59 and 0.51 for Biology and Chemistry respectively. A sample of four hundred and eighty students participated in the…

Abstract: Phosphate solubilising ability of five Streptomyces isolated from the phyllosphere of Heritiera fomes grown in Bhitarkanika mangrove ecosystem was evaluated using tricalcium phosphate (TCP) in both plates and broth culture conditions as well as with and without NaCl. Streptomyces ST24 showed highest solubilization of TCP, with 50.8 and 48.0 mm of halo zone in the plate assay done at pH 7.2 and temperatures 30 and 37°C. Streptomyces ST21, ST24 and ST26 showed good solubilization of TCP in culture medium with 52.15…

Abstract: A total of 9 lactic acid bacteria (LAB) isolated from Egyptian infants, belonging to lactobacilli strains, were screened and selected according to their amino acids production. The isolate strains produced different essential amino acids in fermentation of M17 medium. Lactobacillus strain L1 produced the highest yield of histidine 92.5 mg/l, L2 strain produced the highest amount of asparagine 59.61 mg/l, cysteine 32.96 mg/l, phenylalanine 17.49 mg/l and tyrosine 244.91 mg/l. On the other hand, Lactobacillus strain…

Abstract: The aim of the present study is to determine the antimicrobial activity of the aqueous, chloroform and methanol extracts of the leaves of Dicranopteris linearis (Gleicheniaceae) using the micro-broth dilution method. The leaves of D. linearis were soaked separately in distilled water (dH2O), chloroform and methanol in the ratio of 1:20 (w/v) for 72 h at room temperature, while some part of the methanol extracts was also partitioned with hexane, chloroform and methanol. The target microbe used were Staphylococcus au…

Abstract: There are evidences of relationship between chronic infections of Helicobacter pylori (H. pylori) and gastritis in some previous studies. The gastritis caused by H. pylori leads to a change in serum levels of lipids, lipoproteins, apolipoprotein-A1 (Apo-A1), apolipoprotein- B (Apo-B) and lipoprotein- a (Lp(a)) . These changes will lead to thrombogenesis and other cardiovascular diseases. The aim of this study is to find out a correlation between lipids profiles and helicobacter gastritis. In this study 20 males and…

Abstract: We performed a four year study to investigate the Visceral Leishmaniasis (VL) cases in, Turkey. Fifty-nine patients with suspected VL from Istanbul were included in this work. Bone marrow and blood samples of these patients were tested for possible VL infection using several methods including serological tests, microscopy, PCR. Nineteen (32.2%) patients had positive results for VL after one or more of the tests performed, while only 7 patients (11.8%) had positive results with all the tests including Giemsa stain…

Abstract: Crimean Congo Haemorrhagic Fever (CCHF) is a fatal viral haemorrhagic fever affecting humans. Serious CCHF outbreaks with high mortality have been reported from Asia, Africa and Europe. Endemic CCHF outbreaks have been seen in Turkey between 2002 and 2009, with about 5% mortality rate. People working with animals, people having tick bites, health workers and relatives of CCHF patients may be infected by CCHF virus and therefore they have been considered as CCHF risk groups. In the present study, CCHF prevalence of…

Abstract: 4 different actinomycete strains (A1, A2, A3 and A4) were isolated from the laterite soil samples of Guntur region. Growth pattern and antifungal profiles of the strains were evaluated against the test fungi such as Aspergillus flavus, Aspergillus niger, Candida albicans and Fusarium oxysporum. Based on the cultural, morphological and physiological characteristics, the strains A1, A2 and A4 were identified as the species of Streptomyces while the strain A3 was assigned to Nocardia. Among the 4 tested strains, Strep…

Abstract: The re-introduction of dichlorodiphenyltrichloroethane (DDT) to control mosquitos was recommended by the World Health Organization in 2007. In this study, the potential for biodegradation of DDT by soil microorganisms through enrichment and isolation of DDT biodegraders from soils without a history of prior exposure to DDT was done. Microorganisms from cultivated and uncultivated soils grew in minimal media with DDT (100 ppm) as the only carbon source. Six bacteria coded as isolates 101, 102, 103, 104, 105 and 110…

Abstract: 51 different samples from 5 different manufacturers of ampicillin and ampicillin/cloxacillin suspensions were tested for their levels of active components of ampicillin using the microbiological assay method. Bacillus megathariumNCTC10342A76 was selected from amongst a wide range of organisms screened for this purpose because of its detected suitability. Thin layer chromatography and infra red spectrophotometric analysis confirmed the presence of ampicillin in all the samples and the results obtained showed that th…

Abstract: Bacterial species associated with maedi-visna (MV) infection and occurrence of respiratory disease complex (RDC) in sheep in the cool central highlands of Ethiopia was investigated. Of the 80 sheep examined, 61.25% (n= 49) were found to be MV seropositive and 38.75% (n= 31) were MV seronegative. At post -mortem examination, out of the 49 MV seropositive sheep, 75.51% (n= 37) showed pneumonic lesions in the lungs and a further 23 (74.19%) seronegative sheep were also found pneumonic. Overall, 87.5% (n= 70) of the lu…

Abstract: Bovine leukemia virus (BLV) is a member of the family Retroviridae, genus Deltaretrovirus that has three important gene including gag, pol and env. This virus causes B-cell lymphocytosis and lymphosarcoma in cows. In the first step PCR product of gag gene of BLV isolated in different regions of Iran and BLV-FLK strain was cloned into a pTZ57R/T vector, then insert were digested by BglII and XhoI restriction enzymes and cloned into pET-28(a) as an expression vector. Analysis of the partial bovine leukemia virus (BLV…

Abstract: The efficacy of neem (Azadirachta indica A. Juss), basil (Ocimum basilicum L.) leaf extracts and lambda-cyhalothrin were compared at three levels of concentration against flea beetle, Podagrica spp. (Jac.) in okra. The leaf extracts were applied at 5, 10 and 20 ml per litre while lambda-cyhalothrin was applied at 2.5, 3.75 and 5.0 ml per litre. Distilled water only served as control. In this study, treatment of okra plant with the synthetic insecticide and the leaf extracts against Podagrica spp. using hand spray s…

Abstract: Yoghurt was prepared with two different types of starter cultures that are Lactobacillus bulgaricus and L. acidophilus. In this study 3, 4 and 5% starter cultures were used and stored at 4ºC for 12 days. To analyze the effect of two different cultures and their concentrations on the properties of yoghurt, different physio -chemical tests (protein, lactose, ash, fat, acidity, total solid, pH and moisture) were performed. The results showed that the protein, lactose, ash, fat, acidity and total solid mass were slight…
