Mycobacterium bovis disease in a pediatric renal transplant patient

Mycobacterium bovis hip bursitis in a lung transplant recipient

We present a report of extrapulmonary Mycobacterium bovis infection in a lung transplant recipient. M. bovis is acquired predominantly by zoonotic transmission, particularly from consumption of unpasteurized foods. We discuss epidemiologic exposure, especially as relates to the Mexico-US border, clinical characteristics, resistance profile, and treatment.

Mycobacterium bovis cervical lymphadenitis: A representative case and review

Mycobacterium bovis is a tuberculosis causing bacterium that commonly presents with cervical lymphadenopathy. It is important to differentiate M. bovis from other Mycobacterial pathogens to ensure selection of correct anti-microbial therapy. This may decrease the number of treatment failures, the prevalence of anti-mycobacterial drug resistance patterns, and the need for surgical intervention. M. bovis has universal resistance to pyrazinamide and thus may not respond to typical first line mycobacterial drugs and may require surgical intervention. This case report and review of M. bovis cervical lymphadenitits demonstrates the need for accurate diagnosis as well as combined management with infectious disease and public health specialists.

Tuberculosis following kidney transplantation: report of paediatric case

Recipients of solid organ transplantation are, because of immunosuppressive therapy, at high risk to develop opportunistic infections including tuberculosis (TB). The incidence, clinical manifestations, and optimal diagnostic tests of this disease in this population have not been adequately defined. In this paper, we report a case of 13 year-old boy who developed pulmonary tuberculosis following a second renal transplantation from a deceased donor. The described case points diagnostic difficulties of the tuberculosis disease which are due to insidious and non specific clinical presentation. Also, the treatment is delicate because interaction between immunosuppressive drugs and antituberculosis drugs.

Emerging zoonoses in the southern United States: toxocariasis, bovine tuberculosis and southern tick-associated rash illness

The majority of emerging diseases in humans have been linked to zoonotic pathogens originating in domestic animals or wildlife. This is a public health concern because zoonotic infections affect several aspects of the society. The complex interactions among pathogen, host and environment also pose challenges in estimating the true burden of those infections. However, the recent development of new molecular diagnostic tools has allowed for better diagnosis of zoonotic infections. This review focuses on 3 emerging zoonoses, namely toxocariasis, bovine tuberculosis and southern tick-associated rash illness, and demonstrates that these infections may be more prevalent in the southern United States than previously recognized. This review places special emphasis on the recent epidemiologic trends, intra/interspecies transmission and clinical features of each of these zoonoses. In addition, treatment and prevention for each zoonotic pathogen are discussed. Clinicians working in the southern United States should be aware of the presence of those zoonotic infections.
