Mycoplasmas Isolated from the Respiratory Tract of Cattle and Goats in Tanzania

Isolation af mykoplasmer fra respirationsvejene hos kvœg og geder i Tanzania

Abstract

A microbiological study of the mycoplasma flora in the respiratory tracts of cattle and goats in selected regions of Tanzania is described. In the examination of cattle, mycoplasmas were isolated from 60 (17.8%) of the 338 examined lung samples, 8 (47.1%) of the 17 lymph nodes, 4 (13.3%) of the 30 pleural fluid samples and 4 (3.9%) of the 103 nasal swabs examined. All the isolates were identified as Mycoplasma mycoides subsp. mycoides, Small Colony type except for one isolate from pleural fluid which was identified as Mycoplasma arginini. M. mycoides subsp. mycoides, Small Colony type was isolated from samples originating from Dodoma, Iringa, Mbeya, Morogoro and Shinyanga regions where outbreaks of contagious bovine pleuropneumonia had been reported. In the examination of goats, mycoplasmas were isolated from 54 (34.0%) of the 159 examined lung samples, 41 (18.1%) of the 226 nasal swabs and 4 (40.0%) of the 10 pleural fluid samples. The species demonstrated were Mycoplasma capricolum subsp. capripneumoniae, M. mycoides subsp. mycoides, Small Colony type Mycoplasma ovipneumoniae and M. Capricolum subsp. arginini. The isolation of M. capripneumoniae in the Coast and Morogoro regions confirmed the presence of contagious caprine pleuropneumonia in the regions.

Sammendrag

En mikrobiologisk undersøgelse af mykoplasmer floraen i respirationsvejene hos kvæg og geder i udvalgte regioner af Tanzania er blevet udført. Ved undersøgelsen af kvæg blev mykoplasmer isoleret fra 60 (17,8%) ud af 338 undersøgte lunger, fra 8 (47,1%) af 17 lymfeknuder, fra 4 (13,3%) af 30 prøver fra pleurahule eksudat og fra 4 (3,9%) af 103 næsehulesvabere. Alle isolater blev identificeret som Mycoplasma mycoides subsp. mycoides, Small Colony type på nær eet isolåt identificeret som Mycoplasma arginini hidrørende fra pleurahulen. M. mycoides subsp. mycoides, Small Colony type, blev isoleret fra prøver hidrørende fra Dodoma, Iringa, Mbeya, Morogoro og Shinyanga regionerne, hvorfra udbrud af kontagiøs bovin pleuropneumoni er blevet rapporteret. Ved undersøgelsen af geder blev mykoplasmer isoleret fra 54 (34,0%) af 159 undersøgte lunger, fra 41 (18,1%) af 226 naesehulesvabere og fra 4 (40,0%) af 10 prøver pleurahule eksudat. De påviste arter er M. capripneumoniae, M. mycoides subsp. mycoides, Small Colony type M. ovipneumoniae og M. arginini. Isolationen af M. capripneumoniae in Coast og Morogoro regionerne bekræfter tilstedeværelsen af kontagiøs caprin pleuropneumoni i regionerne.
