1- Synthesis of silver nanoparticles by Bacillus sp.: The microorganisms in the most contaminated toilet Sink were isolated by dilution technique. The dominant bacterial strains are identified as Bacillus sp.‚ on the basis of morphological and biochemical characteristics. Gram’s staining: Gram positive and rod shape. They were serially diluted and spread on nutrient agar plates. The starch has been hydrolyzed and a clear zone by the addition of iodine solution. Visual identification: When bacterial

Pleuropneumonia (CBPP) What is CBPP and what causes it? Contagious bovine pleuropneumonia (plur-OH-new-MOAN-ya)‚ or CBPP‚ is an easily spread respiratory disease of cattle. It is caused by the bacteria Mycoplasma mycoides mycoides (my-COplaz- MA my-COYdees)‚ a similar but different organism than Mycoplasma bovis‚ the bacterium associated with mastitis and shipping fever in cattle. Contagious bovine pleuropneumonia is a serious disease in Africa causing death rates of up to 80%. Occasional outbreaks have
