| LeVier and her colleagues found that Brucella abortus with defective bacA enters mouse cells but can't create a chronic infection. |
| Cultures were considered negative for Brucella only after four weeks of incubation. |
| A separate section of pyogenic, tubercular and brucella infection of the spine is included. |
| This method provides a presumptive indication of Brucella growth at least four days earlier than the conventional identification method. |
| The Brucella abortus vaccine strain B19 carries a deletion in the erythritol catabolic genes. |
| Anthrax, brucella, sarin gas and botulinum toxin can all be released into the atmosphere or water supply. |
