Brucellosis is a zoonosis that is transmissible to humans. It is a disease with multi-systemic involvement caused by the genus Brucella. Neurological complications, including meningitis, meningo-encephalitis, myelitis-radiculoneuritis, brain abscess, epidural abscess and meningo-vascular syndromes, are rarely encountered. We present a patient presenting with acute onset myositis. This kind of presentation has not previously been reported in the English language literature. We conclude that the diagnosis of neuro-brucellosis should be considered in patients presenting with muscle weakness.

Trichinellosis is a zoonosis acquired by the ingestion of insufficiently cooked pork meat containing the encapsulated larvae of Trichinella spiralis. Trichinellosis is presented with myalgia which affects various muscle groups; its intensity is usually related to the severity of the disease and may cause restriction of joint movement. However, joint pain in the course of trichinellosis could not be explained entirely by myositis. This study investigated the other possible causes of restricted movements of joints in animal model. We found that the histopathological changes in the joints of T. spiralis infected rats were in the form of inflammatory cellular infiltrates and ulceration in the synovial membrane with degeneration and ulceration of the articular cartilage. Immunohistochemical examination of the joints revealed the presence of T. spiralis local antigen or immune complex deposited in the synovial membrane. Leukocytosis and eosinophilia were observed throughout the experimental period but eosinophil level declined slowly but still elevated. In conclusion, the restricted movements during the course of trichinellosis seem to be not only due to direct invasion of muscles by the encapsulated T. spiralis larvae but also due to immune complex deposition in the joints.

Human trichinellosis is an important food-borne zoonosis caused by a nematode worm, Trichinella. The symptoms of the disease vary widely depending on the infection load, stage of infection and host immunity and include nausea, vomiting, abdominal pain, fever, facial edema and muscle pain. The disease is usually characterized by moderate to high eosinophilia. We hereby discuss an atypical case of trichinellosis, which presented with myositis of the thigh muscles but had no eosinophilia and no facial or periorbital edema and was associated with osteomyelitis of the femur. The diagnosis was made by the demonstration of anti-trichinella antibodies and later confirmed by the presence of larvae of Trichinella in the digested muscle biopsy. Physicians must be aware of trichinosis and should include it in their differential diagnosis when examining patients with fever and myositis with or without eosinophilia.

Cat scratch disease (CSD) - bartonellosis, is zoonosis caused by the intracellular gram negativebacterium Bartonellahenselae or Bartonellaquintana. The pathogens of this disease enter the human body usually as a consequence of a bite or scratch by young cats which are the natural source of such bacteria. The illness proceeds asymptomatically or with topical symptoms of infection such as a lump, spot or blister. Within 14 days a high fever and topical lymphadenopathy are observed. Lymph nodes are sore and start suppurating. In half of patients, these symptoms may resemble malignancy, and in single cases there are symptoms associated with the musculoskeletal system, such as: osteitis, arthitis and myositis. In paper presented case of 9 year-old girl patients, treated in Oral Surgery Unit due to odema and lymphadenopathy in right submandibular space. Primary surgical treatment of deciduous teeth was conducted without recovery. In few months follow-up, biopsy of lymph node of submandibular group was taken and provisional diagnosis of cat scratch disease was set. Patient was referred to the Infectious Diseases Unit where serological test confirmed cat scratch disease, and pharmacological treatment was conducted with success and recovery of young patient.
