Isolation and Identification of Infectious Agents of Bacterial Flacherie in Bombyx mori (L) | Chapter 9 | Microbiology and Biotechnology Research: An Overview Vol. 1

Sericulture is a highly cost-effective entrepreneurship providing opportunities for farmers to accelerate stable and gainful profits. The primary constraint in silk production is the occurrence of silkworm diseases, particularly Bacterial Flacherie. This disease is caused by a variety of bacteria, including Bacillus subtilis, Streptococcus pneumoniae, Staphylococcus aureus, Pseudomonas fluorescens, and Bacillus cereus. These pathogens have been identified and isolated from infected silkworms using techniques such as colony morphology, staining properties, and biochemical tests. The main objective of this study is to isolate and identify the causative agents of Bacterial Flacherie and this study can help in developing effective control measures, thereby reducing the economic losses caused by disease outbreaks of the specific pathogens responsible for Bacterial Flacherie in Bombyx mori. The significance of this work lies in its potential to contribute to the improvement of silkworm health and productivity.

Importance of Colibacillosis in Poultry | Chapter 5 | Research Perspectives of Microbiology and Biotechnology Vol. 1

Colibacillosis is any diseased condition caused by avian pathogenic E. coli, a Gram negative, non-acid-fast, uniform staining, and non-spore-forming bacillus. It is the most common, prevalent, and important bacterial disease of poultry in the world. E. coli produces toxins like endotoxin, enterotoxin, cytotoxin, hemolysins, hemagglutinins and virulence factors like adhesins. The common predisposing factors include mismanagement in humidity, temperature, ventilation and litter and immunosuppression. The sources of infection are contaminated feed, water and air while route of infection can be aerosol, oral, defected navel and infected egg with incubation period 5-7 days. It commonly causes Colisepticemia, Coligranuloma, Omphalitis, Salpingitis and Peritonitis, etc. Specific diagnosis can be done by identification, isolation and genotyping of E. coli. Suitable susceptible antibiotic can be used for treatment. Control of colibacillosis can be successfully done by proper management, vaccination and biosecurity protocol.
