ABSTRACT: Milk samples from 16 cows that tested positive on the tuberculin test in the state of Paraíba, northeastern Brazil, were used for mycobacteria isolation and identification. Mycobacteria were isolated from five (31.25%) of the 16 milk samples; three samples were classified as M. bovis, and two as belonging to the Mycobacterium genus. This is probably the first study of isolation and identification of M. bovis in milk from cows in Northeastern Brazil, which suggests that humans are at risk of contamination by ingestion.

Abstract:
The tuberculids constitute the immune-mediated non-infectious cutaneous hypersensitivity reaction pattern to the underlying focus of Mycobacterium tuberculosis antigen in patients with good cell-mediated immunity. Papulonecrotic tuberculid (PNT) is a true tuberculid that usually occurs secondary to the underlying focus of infection which may be in the lymph nodes, lungs, bone, or rarely in other systems. It manifests as asymptomatic symmetric eruptions of erythematous papules with central areas of ulceration and crusting that heals with varioliform scars. PNT presenting as a generalized follic

Tuberculosis, still one of the most common infectious diseases globally, manifests primarily as pulmonary tuberculosis. Extra-pulmonary tuberculosis can occur in other sites including skin. Cutaneous tuberculosis, comprising merely 1-2% of all forms of tuberculosis, has been classified into various morphological variants. One of the morphological variants of cutaneous tuberculosis is erythema induratum, a tuberculid, which is caused by hematogenous spread of tuberculosis, the pathogenesis of which is due to hypersensitive reaction against the mycobacterial antigens.

Mycobacteria elicit a cellular immune response in their hosts. This response usually leads to protective immunity, but may sometimes be accompanied by immunopathology due to delayed type hypersensitivity (DTH). A striking example in man is tuberculoid leprosy, which is characterized by high cellular immunity to Mycobacterium leprae and immunopathology due to DTH. Skin lesions of patients suffering from this disease have the characteristics of DTH reactions in which macrophages and CD4+ T lymphocytes predominate.

Mycobacterial antigens produced by the tubercle bacilli consist of several proteins and enzymes. The protein purified from Mycobacterium tuberculosis is called MPT.

It is not a substitute to antigen detection, but it is comparable to the tuberculin test which estimates the cellular immune status.
