Microscopic and bacteriological comparison of paired sputa and transtracheal aspirates.

Bronchopulmonary infection due to Branhamella catarrhalis: 11 cases assessed by transtracheal puncture.

Transtracheal punctures were performed in 193 miners of anthracosilicotic coal who presented with an acute exacerbation of chronic bronchitis. The transtracheal aspirates were bacteriologically positive in 104 patients. Branhamella catarrhalis was isolated in 15 patients; 10 of these responded to chemotherapy, as shown by the resolution of all symptoms and the disappearance of the organism on a...

Sampling variability in the microbiological evaluation of expectorated sputa and endotracheal aspirates.

A five-center study was conducted with the aim of determining how reproducibly expectorated sputa and tracheal aspirates could be sampled when preparing Gram-stained smears and inoculating cultures. With both specimen types, excessive variation was noted among Gram stain results obtained from replicate smears. Less variation was noted among culture results, especially with tracheal aspirates.

Nasopharyngeal aspiration for diagnosis of pulmonary tuberculosis.

BACKGROUND Confirmation of pulmonary tuberculosis (PTB) in young children is difficult as they seldom expectorate sputum. AIM To compare sputa obtained by nasopharyngeal aspiration and by sputum induction for staining and culture of Mycobacterium tuberculosis. PATIENTS AND METHODS Patients from Mulago Hospital, Kampala with symptoms suggestive of PTB were considered for inclusion in the stu...

The relative efficacy of spontaneous sputa, aerosol-induced sputa, and gastric aspirates in the bacteriologic diagnosis of pulmonary tuberculosis.

Comparison of Pasteurella spp. simultaneously isolated from nasal and transtracheal swabs from cattle with clinical signs of bovine respiratory disease.

Twenty-four matched pairs of isolates of Pasteurella haemolytica and three matched pairs of isolates of Pasteurella multocida were isolated by using a nasal swab and a transtracheal swab from individual calves with clinical signs of bovine respiratory disease. The identity of each matched pair was confirmed biochemically and serologically. The similarity of the isolates obtained from a nasal sw...
