Pulmonary tuberculosis due to Mycobacterium bovis in León.

In recent years, human infection due to Mycobacterium bovis has been considered almost eradicated in most industrialised countries. During the period 1998-2002, nine patients were diagnosed with pulmonary tuberculosis (TB) due to M. bovis in the Hospital Monte San Isidro, León, Spain. Their average age was 66 years. The response to therapy was good in seven cases, while two died, one from renal TB and the other from cancer of the pancreatic head.

[Pneumonia diagnosed with bronchoscopy in HIV-positive patients].

BACKGROUND: The object of our research is to analyse the microbiological results of the samples which have been obtained by means of fibronchoscopy (FB) from HIV positive patients from 1991 until 1993. METHODS: Sixty fibrobronchoscopies were carried out on fifty-seven HIV positive patients. In every case, samples of bronchoaspirate (BAS), bronchoalveolar lavage (BAL) and telescoping plugged catheter (TPC) were cultured; the last two in a quantitative way. Pneumocystis carinii was investigated in BAL by means of immunofluorescence with monoclonal antibodies. RESULTS: Some microorganisms were isolated in forty-seven bronchoscopies. Thirteen episodes resulted negative. The most frequent etiologic agent was Pneumocystis carinii (seventeen cases). The etiology of fifteen episodes was polymicrobial. The intersticial radiological pattern was the predominant one. It was observed in twenty-seven cases. With regard to immunity, 91% of the patients showed CD4 < 200. CONCLUSIONS: In our research work, the samples that have been obtained by means of FB showed a high percentage of diagnoses; that is the reason why we regard this technique as very useful for the diagnosis of pneumonia in patients with AIDS. Due to the large number of bacterian pneumonia, we consider necessary not only the use of BAL, but also that of TPC in these processes.

The complete sequence of an 18,002 bp segment of Saccharomyces cerevisiae chromosome XI contains the HBS1, MRP-L20 and PRP16 genes, and six new open reading frames.

We report the sequence of an 18,002 bp DNA fragment from the right arm of Saccharomyces cerevisiae chromosome XI. This segment contains nine complete open reading frames (ORFs), YKR401 to YKR409, and part of another ORF, YKR400, covering altogether 87.2% of the entire sequence. One of them, YKR400, encodes an NAD-dependent 5,10-methylene-tetrahydrofolate dehydrogenase. YKR404, YKR405 and YKR406 correspond to the previously characterized HBS1, MRP-L20 and PRP16 genes, coding for a translation elongation factor, a mitochondrial ribosomal protein and an ATP-binding protein, respectively. The putative product of YKR407 contains the zinc-binding region signature of neutral zinc metallopeptidases. The five other ORFs do not show significant homology to any known protein.
