          Brucellosis is a multisystem infection found worldwide that has a broad range of characteristics, which range from acute fever and hepatomegaly to chronic infections that most commonly affect the central nervous system, cardiovascular system, or skeletal system. Gastrointestinal and splanchnic artery involvements in brucellosis are relatively uncommon.

          Patient concerns:

          We report a case of brucellosis in an adolescent presenting as intermittent abdominal pain, diarrhea, and fever, with intestinal tract involvement. And stenosis of the celiac artery and the superior mesenteric artery was found after exposed to risk factors of Brucella infection. Splanchnic vessels stenosis and an endothelial lesion may exacerbate the prevalent symptom of abdominal pain, as a form of colic pain, occurring after eating.


          The patient was diagnosed as brucellosis. The narrowing of the SMA and CA was suspected to be vasculitis secondary to the brucellosis.


          The patient was treated with minocycline and rifampicin for 12 weeks totally.


          The gastrointestinal manifestations of brucellosis recovered rapidly under intensive treatment. However, follow-up imaging revealed that the superior mesenteric artery and celiac artery stenosis was unimproved.


          In brucellosis, gastrointestinal manifestations may be the only observable features of the disease. Splanchnic arterial stenosis is a rare complication of brucellosis. Sonography and computed tomography may be useful for both diagnosis and follow-up.

          Clinical manifestations and complications in 1028 cases of brucellosis: a retrospective evaluation and review of the literature.

          Brucellosis is the most prevalent bacterial zoonosis worldwide. In this study, we aimed to compare our 1028 brucellosis cases with other big series in the literature in view of epidemiological, clinical, and laboratory findings and therapeutic features. A total of 1028 brucellosis cases admitted to the Department of Infectious Diseases and Clinical Microbiology over a 10-year period were included in the study. A retrospective analysis was undertaken and patient files were reviewed for history, clinical and laboratory findings, and therapeutic features, as well as complications. Of the 1028 patients, 539 (52.4%) were female and 489 (47.6%) were male. The mean age of patients was 33.7+/-16.34 years and 69.6% of cases were aged 13-44 years. Four hundred and thirty-five cases (42.3%) had a history of raising livestock and 55.2% of the cases were found to have no occupational risk for brucellosis. Six hundred and fifty-four of the cases (63.6%) had a history of raw milk and dairy products consumption. The most frequently seen symptoms were arthralgia (73.7%) and fever (72.2%), while the most common clinical findings were fever (28.8%) and hepatomegaly (20.6%). The most frequent laboratory finding was a high C-reactive protein level (58.4%). The standard tube agglutination (STA) test+Coombs STA test was positive in 1016 cases (98.8%). Focal involvement was present in 371 (36.1%) cases. The most frequent involvement was osteoarticular involvement with 260 cases (25.3%). The overall relapse rate for patients with brucellosis was 4.7%. The highest relapse rate, 8.5%, was observed in the group of patients with osteoarticular involvement. Regimens including doxycycline and streptomycin with or without rifampin appeared more effective than other regimens in osteoarticular involvement. In humans, brucellosis may lead to serious morbidity, and it continues to be a major health problem in Turkey. There is no recommended treatment protocol for complicated brucellosis. Large multicenter studies are needed to determine the most appropriate treatment choices and durations in complicated brucellosis. Copyright 2009 International Society for Infectious Diseases.

            Establishment of systemic Brucella melitensis infection through the digestive tract requires urease, the type IV secretion system, and lipopolysaccharide O antigen.

            Human brucellosis is caused mainly by Brucella melitensis, which is often acquired by ingesting contaminated goat or sheep milk and cheese. Bacterial factors required for food-borne infection of humans by B. melitensis are poorly understood. In this study, a mouse model of oral infection was characterized to assess the roles of urease, the VirB type IV secretion system, and lipopolysaccharide for establishing infection through the digestive tract. B. melitensis strain 16M was consistently recovered from the mesenteric lymph node (MLN), spleen, and liver beginning at 3 or 7 day postinfection (dpi). In the gut, persistence of the inoculum was observed up to 21 dpi. No inflammatory lesions were observed in the ileum or colon during infection. Mutant strains lacking the ureABC genes of the ure1 operon, virB2, or pmm encoding phosphomannomutase were constructed and compared to the wild-type strain for infectivity through the digestive tract. Mutants lacking the virB2 and pmm genes were attenuated in the spleen (P < 0.05) and MLN (P < 0.001), respectively. The wild-type and mutant strains had similar levels of resistance to low pH and 5 or 10% bile, suggesting that the reduced colonization of mutants was not the result of reduced resistance to acid pH or bile salts. In an in vitro lymphoepithelial cell (M-cell) model, B. melitensis transited rapidly through polarized enterocyte monolayers containing M-like cells; however, transit through monolayers containing only enterocytes was reduced or absent. These results indicate that B. melitensis is able to spread systemically from the digestive tract after infection, most likely through M cells of the mucosa-associated lymphoid tissue.

              Human brucellosis in the People's Republic of China during 2005-2010.

              Brucellosis is a worldwide re-emerging zoonotic disease. It remains a serious public health problem in many developing countries including China. This review summarizes the epidemiological characteristics, morbidity, and endemic distributions of human brucellosis in the People's Republic of China for the period 2005-2010. From 2005 to 2010, the incidence of human brucellosis rose substantially in China, especially in the provinces of Inner Mongolia, Shanxi3, Heilongjiang, Hebei, Jilin, and Shanxi1. Meanwhile human brucellosis increased gradually in some southern provinces, such as Henan, Guangdong, and Fujian. Due to the rapid expansion of human brucellosis in China, surveillance and prevention of this disease has been greatly challenged.
