Caution Avoid drinking unpasteurized milk products and practice good veterinary vaccination practices to avoid natural forms of brucellosis. In a terrorism attack with aerosol, livestock could possibly become contaminated. If this occurs, animal products should be pasteurized, boiled, or thoroughly cooked prior to eating. Water would have to be treated by boiling or iodination after any intentional contamination with brucella aerosols. 

The recommended treatment is doxycycline (200 mg/day) plus rifampin (600 mg/day) for six weeks. An alternative effective treatment is six weeks of doxycycline (200 mg/day) plus streptomycin (1 gm/day) for three weeks. Trimethoprim-sulfamethoxazole given four to six weeks is less effective. In 5 to f 0 percent of cases, there may be a relapse or treatment failure. Regarding prophylaxis, killed and live attenuated human vaccines are available in many countries but are considered of unproven efficacy. There tends to be no information on the use of antibiotics for prophylaxis against human brucellosis. 

Vaccines There is no human vaccine available for brucellosis, although there are a number animal vaccines since this disease is one of the most important veterinary diseases in the entire world. 

Additional considerations include vaccinations of investigators against rabies or tuberculosis, especially when working with some mammals and their parasites. These preventative measures are needed to protect the researcher. Animal necropsy should include protective clothing and the containment of possible biohazards, in order to avoid contracting diseases such as psittacosis, erysipelas, rickettsial infections, and brucellosis.5 The...

For the vaccine against brucellosis (Figure 2) [33], an optimal freeze-drying efficiency is observed for a residual moisture in the vicinity of 2.8% on the other hand, preservation during storage is best for the lower levels of residual moisture. The optimal result appears to be obtained for a residual moisture level in the vicinity of 2% (Figure 3). 

F. Vaccination. Vaccination is the preferred method of biological defense. Fully licensed vaccines are currently available for anthrax, cholera, plague and smallpox. Vaccines for botulinum toxoid, Q fever, Rift Valley fever, tularemia, and VEE currently exist as IND products and would be available only under protocol with informed consent, therefore would not be readily available on the battlefield. No vaccine is currently available either FDA licensed or under IND status, for glanders, brucellosis, Staphylococcus enterotoxin B, ricin, or T-2 mycotoxins. 

All of the current R D on brucellosis located by the committee focuses on development of a vaccine. As noted above, the committee considers it unlikely that a vaccine could be usefully employed for protection from a domestic terrorist attack and therefore considers such R D a low priority for improving civilian medical capability. Antibiotic treatment, though not simple, is possible with current products. USAMRIK) conducts assays of second-and third-generation antibiotics as they come on the market, using all of the bacterial threat agents in animal models. 

Documented effects Saponins from this species increase the secretory activity of glands. Pure saponin from this species is used in veterinary medicine to prepare vaccines against anthrax and brucellosis (Khodzhimatov 1989). Treatment with a saponin extracted from the roots antagonized the narcotic effect of chloral hydrate, potentiated the convulsive effect of strychnine, decreased the convulsive and toxic effect of Corazole, and increased dieresis in mice (Polievtsev and Sultanov... 

Some years ago, brucellosis was a common disease in farm animals, due to three Brucella organisms B. suis (pigs), B. abortus (cattle) and B. melitensis (sheep and goats). In recent years, the incidence of the disease has dramatically decreased due to extensive animal prophylaxis programs, including elimination of infected animals and vaccination of healthy ones it is well controlled in many European countries but is still common in some parts of the world. 

Brucellosis is caused by three different gramnegative rods Brucella suis from pigs. B. abortus from cattle, and B. melitensis from sheep and goats. Infection is from handling infected animals or ingesting contaminated unpasteurized milk or cheese. The skin manifestations can include maculopapular lesions, petechiae, a chronic ulcer at the site of inoculation, and an urticarial eruption with subsequent vesiculopustules. Treatment is oral tetracycline plus intramuscular streptomycin. Prevention of brucellosis in humans is based on elimination of animal brucellosis. Immunization of animals is done using a live attenuated Brucella vaccine.

In contrast to orf, brucellosis infection has developed in humans following self-injection with live brucella vaccine. In the USA, the Centers for Disease Control and Prevention (CDC) received reports of 26 cases through passive surveillance and 21 of these had suffered needle stick injuries with contaminated needles used for animal vaccination, 4 had received conjunctival spray exposure and one individual had contamination through an open wound. There were no cases of brucellosis in these subjects. There is currently insufficient data to determine if the strain involved can cause systemic brucellosis in humans. " Self-injection with Mycobacterium paratuberculosis bacterin (Johne s disease bacterin) produced only minor local reactions.
