A study was conducted to compare Gram positive (Lactobacillus rhamnosus and Berevibacillus laterosporus) and Gram negative probiotics’ bacteria (E. coli Nissle 1917) with antibiotic (Virginiamycin) on serum biochemistry and intestinal microflora in broiler chicks. Total of 140, one-day old male Ross 308 broiler chicks were subjected to a 42-day experimental period. The chicks were divided into ...

Two experiments were performed to screen bacilli isolated from quails for their aflatoxin removal potential and to assess the efficiency of their amelioration of experimental aflatoxicosis. Nonhemolytic bacilli were selected for in vitro aflatoxin B1 (AFB1) removal and conventional probiotic tests. The isolate with the highest scores was selected for assessment in field experiments and was iden...

Brevibacillus laterosporus has been isolated from many different environments, including beehives, and produces compounds that are toxic to many organisms. Five B. laterosporus phages have been isolated previously. Here, we announce five additional phages that infect this bacterium, including the first B. laterosporus siphoviruses to be discovered.

In present study Bacillus laterosporus isolated from a commercial formulation showed larvicidal activity against second instar larvae of Aedies aegypti, Anophles stephense and Culex qunquefasciatus. The % mortality without heat treatment was 37.34 against Anophles and 18.67 against Culex. The toxin was heat stable and its toxicity increased with inoculum size and incubation time. The study reve...

The Bacillus laterosporus strains 921 and 615 were shown to have toxicity for larvae of the mosquitoes Aedes aegypti, Anopheles stephensi, and Culex pipiens. The larvicidal activity of B. laterosporus was associated with spores and crystalline inclusions. Purified B. laterosporus 615 crystals were highly toxic for Aedes aegypti and Anopheles stephensi.

Outer spore envelope proteins of pathogenic bacteria often present specific virulence factors and tools to evade the defence system of their hosts. Brevibacillus laterosporus, a pathogen of invertebrates and an antimicrobial-producing species, is characterised by a unique spore coat and canoe-shaped parasporal body (SC-CSPB) complex surrounding the core spore. In the present study, we identifie...

Volume 1, no. 6, e00668-13, 2013. The species infected by the five bacteriophages was misidentified as Paenibacillus larvae. The article title should read as given above, and the organism identified as Paenibacillus larvae should be identified as Brevibacillus laterosporus throughout. Page 1: The abstract should read as follows. “Brevibacillus laterosporus is a secondary invader following Europ...

The potential of two bioinsecticidal formulations containing Brevibacillus laterosporus spores and azadirachtin, respectively, was assayed in laboratory and in comparative field treatments for the management of immature house flies on dairy farms. As already known for B. laterosporus, preliminary laboratory experiments with azadirachtin evidenced a concentration-dependent effect. Azadirachtin m...
