Background: Fly-borne diseases are still a health problem in urban and rural communities, such as related to the gastrointestinal tract, abdominal typhus, cholera, typhoid fever, diarrhoea, dysentery, others. The simplest most common mode of transmission is mechanical. In this method, vector spreads parasite through contact with host without breeding on fly.Objectives: This study aimed determin...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
Bacillus thuringiensis subsp. israelensis (Bti) is increasingly used worldwide for mosquito control and is the only larvicide used in the French Rhône-Alpes region since decades. The artificial selection of mosquitoes with field-persistent Bti collected in breeding sites from this region led to a moderate level of resistance to Bti, but to relatively high levels of resistance to individual Bti ...
The inhibitor cystine knot (ICK) is an unusual three-disulfide architecture in which one of the disulfide bonds bisects a loop formed by the two other disulfide bridges and the intervening sections of the protein backbone. Peptides containing an ICK motif are frequently considered to have high levels of thermal, chemical and enzymatic stability due to cross-bracing provided by the disulfide bon...
This minireview discusses the risks to humans and large mammals associated with the use of Bacillus thuringiensis var. kurstaki (Btk) in forest, agricultural and urban environments. The first subspecies used for insect control was Bacillus thuringiensis subsp. thuringiensis (Btt), known at the time as Bt Berliner. Much of the early work done with Bt does not identify the subspecies. Btk is regi...
malgré l’influence indéniable de l’étendu du vocabulaire sur le niveau de maîtrise des apprenants, connaitre un grand nombre d’unités lexicales ne suffit pas au perfectionnement dans la production langagière. la connaissance lexicale peut être active et productive ou passive et réceptive. notre objectif est de trouver une solution pour enseigner un vocabulaire actif et disponible. dans le pre...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
The subterranean termite Coptotermes curvignathus is a type of insect that damages wood until it porous and destroyed. Until now, termites are chemically controlled but negatively impact the environment, so bioinsecticides such as from Usnea barbata lichen needed. This study aims to determine bioactivity U extract. Barbata bioinsecticide for C. curvignathus. experiment used Completely Randomizd...
Bioinsecticides based on Bacillus thuringiensis (Bt) are widely used to control agricultural pests. However, there concerns about their impact non-target organisms, with for example, the green lacewing Ceraeochrysa claveri, a polyphagous predator important value in biological of insect pests agroecosystems. This study aimed analyse effects Agree® bioinsecticide (containing Bt serovar aizawai GC...
