Objectives

Brucellosis is caused by various species of the genus Brucella, Gram-negative, facultative intracellular b a c t e r i a ( c o c c o b a c i l l u s o r s h o r t rods). Each Brucella species is associated most often with certain mammalian hosts. Brucellosis is a systemic infection with a broad clinical spectrum, ranging from asymptomatic disease to severe and/or fatal illness. Brucella can involve multiple organs and tissues. Clinical and laboratory features vary widely . The main presentations are acute febrile illness with or without signs of localization, and chronic infection. We aimed to review the clinical and laboratory features of patients with brucellosis.

Metods

In the present study, we retrospectively evaluated demographic, clinical and laboratory data, treatment modalities of the patients with brucellosis between January 1998 and December 2012. The diagnosis of brucellosis was made by positive Wright test (titer>= 1/160) and/or by isolation of brucella in blood In the present study, we retrospectively evaluated demographic, clinical and laboratory data, treatment modalities of the patients with brucellosis between January 1998 and December 2012. The diagnosis of brucellosis was made by positive Wright test (titer>= 1/160) and/or by isolation of brucella in blood culture.

Result

166 patients were included in the study, of those 85 (51,2 %) of were female and 81 (51,2 %) were male. Mean age was 44 ± 18. Seventy (42,2%) patients applied at subacute period, 72(43,4%) at acute period and 24 (14,5%) at chronic period. Eighty two (49,4%) of patients developed complications. The complications were encountered most commonly between the age 15 - 45 (n=91 54,8%). Osteoarticuler complications were the most common complication (n=35 38%) (g.

Conclusions

Brucellosis may present with different symptoms and clinical signs. It should not be forgotten that if it is not diagnosed in time, it can advance to chronic disease in older ages and osteoarticuler complications can occur. For cases who live in endemic areas and who live in non-endemic areas with a travelling history to endemic areas presenting with complaints such as fever, rash, low back pain, nausea, vomitting brucellosis should be kept in mind.
