ABSTRACT
Abstract

Objective:

The aim of the study was detection of two major causative agents of pleuropneumonia, Mycoplasma capricolum subsp. capripneumoniae (Mccp) and Mannheimia haemolytica, in goats. To the best of our knowledge, this study is the first investigation of Mccp in Iran.

Methods:

50 grossly suspected lungs to pleuropneumonia and 10 healthy samples were collected from Shiraz abattoir.

Results:

Histopathological evaluation of tissue samples showed various diagnosed pneumonias including 40% bronchointerstitial pneumonia (20 samples), 34% interstitial pneumonia (17 samples), 10% fibrinopurulent bronchopneumonia (5 samples), 12% purulent bronchopneumonia (6 samples) and 4% chronic pneumonia (2 samples). In molecular study, all 50 suspected samples and 10 healthy ones by PCR showed no Mccp positive sample, but the detection rate of M. haemolytica in suspected samples was 14% and in healthy lungs was zero.

Conclusions:

It may be concluded that goats referred to Shiraz abattoir is free of Mccp. Further sampling and molecular testing at the level of suspected herds to CCPP can be useful.
RESUMEN
Resumen

Objetivo:

El objetivo del estudio fue la detección de dos agentes causantes principales de pleuroneumonía, Mycoplasma capricolum subsp. Capripneumoniae (Mccp) y Mannheimia haemolytica, en cabras. Hasta donde sabemos, este estudio es la primera investigación de Mccp en Irán.

Métodos:

50 pulmones muy sospechosos de pleuroneumonía y 10 muestras sanas se obtuvieron del matadero de Shiraz.

Resultados:

La evaluación histopatológica de muestras de tejido mostró varias neumonías diagnosticadas, incluyendo 40% de neumonía broncointersticial (20 muestras), 34% de neumonía intersticial (17 muestras), 10% de bronconeumonía fibrinopurulenta (5 muestras), 12% de bronconeumonía purulenta (6 muestras) y 4% neumonía crónica (2 muestras). En un estudio molecular, las 50 muestras sospechosas y 10 sanas por PCR no mostraron una muestra positiva de Mccp, pero la tasa de detección de M. haemolytica en muestras sospechosas fue del 14% y en pulmones sanos fue cero.

Conclusiones:

se puede concluir que las cabras referidas al matadero Shiraz están libres de Mccp. La realización de muestreo adicional y pruebas moleculares a nivel de rebaños sospechosos para CCPP puede ser útil.
