1/8. Swelling of hand and forearm caused by mycobacterium bovis.

    A 75-year-old native Dutch farmer presented with a painless swelling of his right hand extending into his forearm, accompanied by general malaise and low grade fever. His medical history revealed coxitis tuberculosa in 1954 and injury of the same hand in 1978. His present swelling appeared to be caused by mycobacterium bovis, probably due to endogenous reactivation. Whether the mycobacteria reached the hand hematogenously or were directly inoculated at the time of injury of his hand in 1978 remains unclear.

2/8. mycobacterium bovis infection, United Kingdom.

    We describe the first documented spillover of bovine tuberculosis from animals into the human population of the United Kingdom since the resurgence of the disease in cattle in the country. This finding suggests that there may be a small risk for transmission to humans, making continued vigilance particularly necessary.

3/8. Molecular and histopathologic evidence for systemic infection by mycobacterium bovis in a patient with tuberculous enteritis, peritonitis, and meningitis: a case report.

    mycobacterium bovis infection has been reported in several patients with AIDS in other countries. The prevalence of tuberculosis in taiwan is higher than the world health organization standard. However, reports of M. bovis infection are rare. A 47-year-old male had the habit of drinking uncooked fresh deer's blood and unpasteurized deer's milk. He suffered from acute abdominal pain and underwent emergency laparotomy. pathology demonstrated tuberculosis enteritis with colon perforation. The molecular diagnosis by nested polymerase chain reaction assay and single-strand conformation polymorphism assay showed M. bovis infection in the small intestine, mesenteric lymph nodes, and cerebrospinal fluid (CSF). Our results suggest that the most likely portal of entry of M. bovis is the gastrointestinal rather than the respiratory tract. Ingested M. bovis from unpasteurized deer's milk probably entered the mucosal macrophages of the intestine and then the draining mesenteric lymph nodes. As immunity declined, bacilli from the mesenteric lymph nodes disseminated to other organs and into the CSF.

4/8. mycobacterium bovis tuberculosis: from animal to man and back.

    Rare cases of tuberculosis due to mycobacterium bovis have been described in humans who have been exposed to cattle or other infected animals. We report a case of tuberculosis in cattle exposed to a patient infected with M. bovis, where the strain isolated in the cattle and the patient were identical. As the patient is reported to have been exposed and contaminated during childhood, this seems to be the first documented case of transmission of M. bovis from animal to man and back to animal.

5/8. Variable outcome of experimental interferon-gamma therapy of disseminated bacillus Calmette-Guerin infection in two unrelated interleukin-12Rbeta1-deficient Slovakian children.

    mycobacterium bovis bacillus Calmette-Guerin (BCG) is an attenuated live vaccine that may cause life-threatening clinical disease in children with impaired immunity. In particular, patients with any of the nine known inherited disorders of the interleukin-12/23 interferon-gamma (IL-12/23-IFNgamma) axis are highly vulnerable to BCG. We describe two unrelated young Slovakian children suffering from disseminated BCG infection which developed shortly after routine BCG vaccination after birth. During treatment with selected anti-BCG antibiotics, resistance against several of these drugs developed. In both children, interleukin-12/23 receptor beta1 (IL-12/23Rbeta1) deficiency was diagnosed. Thus, in addition to chemotherapy, immunomodulatory treatment with recombinant IFN-gamma was performed as the pathogenesis of BCG disease in IL-12Rbeta1 deficiency involves impaired IL-12- and IL-23-dependent IFN-gamma production by lymphocytes. One child responded to treatment and is presently doing well whereas the second patient died. Conclusion:The marked variability of outcome of disseminated bacillus Calmette-Guerin disease in interleukin-12/23 receptor beta1-deficient children sharing the same ethnic origin and exposed to a similar environment as presented in these case reports has to be taken into consideration for diagnosis and treatment of infections due to this genetic defect.

6/8. mycobacterium bovis as an occupational hazard in abattoir workers.

    Five cases of bovine tuberculosis occurred in a two year period in south australia, which represents a higher incidence than in previous years. All five patients had a history of employment in an abattoir (although four different abattoirs were involved) and four of the cases had pulmonary or pleural TB. A voluntary survey of one of the abattoirs was conducted which discovered the fifth case of active pulmonary TB. We suggest that bovine TB should be considered an occupational hazard in abattoir workers, and that suitable pre-employment screening programmes for workers be established. The transmission of disease in these cases is almost certainly by inhalation causing pulmonary TB and is therefore different from the 'classic' form of bovine TB transmitted by ingestion of infected milk and resulting in extrapulmonary disease.

7/8. Primary lingual tuberculosis caused by M. bovis infection.

    Although tuberculosis of tongue has been previously reported, its infrequent clinical presentation and increased chance of being overlooked during routine examination of the oral cavity, make it worthy of documentation. Lingual tuberculosis is usually associated with tuberculosis of the oropharynx, lungs, lymph nodes, and miliary tuberculosis. Primary tuberculosis of the tongue is extremely rare and is seldom reported. early diagnosis of tuberculosis elsewhere in body and its effective treatment by antituberculous drugs may be the reason for its uncommon presentation. The relationship between consumption of raw or unboiled milk and tuberculosis of the tongue is ill-understood and has evidently not been reported. We take this opportunity to present the first case of primary lingual tuberculosis caused by mycobacterium bovis related to consumption of unboiled cow milk.

8/8. Mycobacterial sepsis following intravesical instillation of bacillus Calmette-Guerin.

    Intravesical bacillus Calmette-Guerin (BCG) administration for bladder cancer may lead to BCG dissemination in the compromised host. A case of a 63-year-old man with shock secondary to BCG sepsis is reported. The recognition and treatment of disseminated BCG infection are discussed. In addition to standard therapy for urosepsis, early therapy with steroids and coverage with antitubercular medications should be initiated for patients with this condition. In general, the author recommends that all febrile patients who have received BCG immunotherapy within three years, and who have no obvious source for their fever, have acid-fast bacilli blood cultures done for mycobacterium bovis, and that these patients be admitted to the hospital for further evaluation.
