Efficacy of immunization with the recombinant collagen adhesin A region against Staphylococcus aureus–induced mouse mastitis
Staphylococcus aureus (S. aureus) is a major cause of bovine mastitis. In this present study, we assessed the efficacy of the recombinant A region of collagen adhesin (rCna-A) as a mastitis vaccine in a mouse model. Three groups of mice were immunized with either rCna-A, inactivated S. aureus, or phosphate-buffered saline (PBS) as a control. IgG and IgG subtype titers of mice in the rCna-A vaccine...

Seasonal habitat use and movement patterns of cattle grazing different rangeland types in the communal areas of the Eastern Cape, South Africa
Understanding cattle ranging behaviour and habitat selection in African communal rangelands helps to inform resource management strategies. This study investigated seasonal variation in habitat selection and home range size of cattle in two rangeland types in communal areas of the Eastern Cape of South Africa. The average annual home range size of cattle was larger in the sweetveld than the coastal forest...

Antioxidant enzyme and morphological characteristics of roots of three Nicotiana Tabacum L. genotype seedlings under chilling stress
In order to study the morphological and physiological ecological response of root of Flue-cured tobacco seedling after low temperature stress, this experiment was conducted with different stressful period which was 2, 4 and 6 days under 5 to 7°C (day) by the material named Yunyan87, Msk326 and Yunyan85, respectively. The results showed that comparing with favorable temperature (23 to 25°Cday),...

Zinc/phosphorous ratio in shoot as an index of evaluating rice salt tolerance
Rice genotypes of varying salt tolerance [tolerant (T), semi-tolerant (ST) and sensitive (S)] were evaluated in field lysimeters that contained saline soil of ECe 4 and 8 mS cm-1 and alkali soil of pH 9.5 and 9.8 in Karnal, North India. Tolerant rice genotypes accumulated lesser Na+ and higher K+, which led to lower Na/K...

Soil and nutrient losses along the chronosequential forest recovery gradient in Mabira Forest Reserve, Uganda
Information on the effect of Mabira Forest Reserve degradation on water, soil and nutrient losses is scanty. This study was carried out to quantify runoff, soil and nutrient losses in six restoring forest regimes namely: 0 to 3, 10 to 20, 20 to 30, 30 to 40, 40 to 50, and >55 years of last disturbance. In each, a plot measuring 150 by 50 m was demarcated. Within this plot, three sub-plots each of 20...

Macrofauna of soil treated with swine wastewater combined with chemical fertilization
This study aimed to evaluate the effects of the application of swine wastewater treated in anaerobic digester(0, 100, 200, and 300 m3 ha-1) combined with nitrogen fertilization (doses of 0 and 100% of the recommendedculture of baby corn) on the edaphic macrofauna. Pitfall traps were used in the evaluation of the macrofauna and the collected organisms were...

Characterization of nematicidal activity of plant residues and their application with moisture approach against Meloidogyne incognita in tomato
Eco-friendly methods and strategies for nematode management have been recommended due to their non hazardous impact on environment. In this current study, experiment was conducted to control Meloidogyne incognita in tomato cv. ‘K25’ by using organic amendment as dip or soil-additive. The root-dip treatment ofJusticia adhatoda L. inhibited larval penetration in roots of tomato...

Microbial load of processed Parkia biglobosa seeds: Towards enhanced shelf life
Parkia biglobosa seed is one of the major sources of plant protein in African diet. This work was carried out to improve the shelf-life of the processed seeds of P. biglobosa. The microbial count of the micro-organisms (responsible for the fermentation of the processed seed), sensory and physical characteristics were evaluated on fermented seeds preserved with various salt concentration. Our...
