Background: Human brucellosis is common in southern Israel among the semi-nomadic Bedouin, a population that consumes unpasteurized dairy products. Though camel milk ingestion is a known mechanism for brucellosis acquisition, only a few reports of sporadic cases have been published in the medical literature.

Objectives: To describe a local brucellosis outbreak in 15 extended Bedouin family members, following ingestion of infected camel milk.

Methods: Data regarding patient’s clinical manifestations, laboratory findings, treatment and outcome were collected from the hospital and the health fund clinics’ computerized database. Camel’s blood and milk were tested for Brucella serology and culture. Cases were defined by positive Rose Bengal test, symptoms correlating with brucellosis, and consumption of infected camel milk.

Results: Fifteen patients were diagnosed with acute brucellosis from March to June 2011. Sixty percent of cases had serum agglutination test titers of 1:160 or higher and 4/8 (50%) had positive blood culture for Brucella melitensis. Arthralgia and fever were the most consistent clinical manifestations. Blood and milk serology and milk culture taken from the female camel were positive for Brucella melitensis.

Conclusions: The treating physicians must consider the possibility of infected camel milk ingestion as the mode of infection, both in sporadic cases and in outbreaks of brucellosis.

Background: Transmission of Pseudomonas aeruginosa among cystic fibrosis patients attending health camps has been reported previously.

Objectives: To determine the transmission of P. aeruginosa among CF[1] patients during three winter camps in the Dead Sea region in southern Israel.

Methods: Three consecutive CF patient groups were studied, each of which spent 3 weeks at the camp. The patients were segragated prior to camp attendance: patients who were not colonized with P. aeruginosa constituted the first group and colonized patients made up the two additional groups. Sputum cultures were obtained upon arrival, at mid-camp and on the last day. Environmental cultures were also obtained. Patients were separated during social activities and were requested to avoid social mingling. Isolates were analyzed by antibiotics susceptibility profile and by pulsed field gel electrophoresis.

Results: Ninety isolates from 19 patients produced 28 different fingerprint patterns by PFGE[2]. Isolates from two siblings and two patients from the same clinic displayed the same fingerprint pattern. These patients were already colonized with these organisms upon arrival. Two couples were formed during the camp, but PFGE showed no transmission of organisms. All other patients' isolates displayed unique fingerprint patterns and were distinguishable from those of other attendees, and none of the P. aeruginosa-negative patients acquired P. aeruginosa during camp attendance. Environmental cultures were negative for P. aeruginosa.

Conclusions: We were unable to demonstrate cross-infection of P. aeruginosa among CF patients participating in health camps at the Dead Sea who were meticulously segregated.
