چکیده

Indole spot tests using isolated, nonhemolytic colonies of Haemophilus species were positive for 90 of 151 (60%) respiratory isolates of Haemophilus influenzae, whereas 67 to 72 (93%) isolates of H. influenzae from cerebrospinal fluid and blood specimens were indole positive. Only 4 of 117 (3%) Haemophilus parainfluenzae isolates were positive for indole spot tests. Thus, indole-positive, nonhemolytic Haemophilus isolates in respiratory cultures can be presumptively identified as H. influenzae.

Characterization of Haemophilus spp. isolated from healthy swine and evaluation of cross-reactivity of complement-fixing antibodies to Haemophilus pleuropneumoniae and Haemophilus taxon "minor group".

Of 30 sows from a herd believed to be free of Haemophilus pleuropneumoniae infection, 2 had complement-fixing antibodies to H. pleuropneumoniae serotype 5. Necropsy and microbiological examination of the two sows revealed no evidence of H. pleuropneumoniae infection; however, Haemophilus taxon "minor group" and a urease-negative, indole-positive Haemophilus sp. were isolated from numerous respi...

Development of a test system for rapid differentiation of Neisseria and Haemophilus spp.

A qualitative micromethod (IDS Rapid NH system) employing conventional and single-substrate enzyme tests was developed for the biochemical characterization of Neisseria spp., Haemophilus spp., and other gram-negative species. A total of over 140 dehydrated, miniaturized biochemical tests were investigated for their ability to distinguish species. Computer-assisted test selection and pair separa...

Rapid Biotyping of Haemophilus influenzae and Haemophilus parainfluenzae with PathoTec Strips and Spot Biochemical Tests BILLIE

PathoTec strips and spot biochemical tests were evaluated for the ability to biotype Haemophilus influenzae and Haemophilus parainfluenzae. Indole, urease, and ornithine decarboxylase reactions were tested. The results of PathoTec strips compared favorably with those conventional methods; the percent agreements were as follows: indole, 100; urease, 99.5; and ornithine, 97.5. Spot tests were sim...

Control of Bipolaris Oryzae the Causal Agent of Rice Brown Spot Disease Via Soil Streptomyces Sp. Isolate G

Bipolaris oryzae causes rice brown spot disease which reduces rice yield with substantial global impact. Streptomycetes isolated from rice fields of Guilan Province, Iran, showed antifungal activity against the tested pathogen. From five active Streptomyces spp. isolates, isolate G showed high antagonistic activity. To determine its taxonomical identity, its colonies character...
