Abstract

Mycoplasma hyopneumoniae, cause of enzootic pneumonia is known for serious economic losses in pigs. The disease is prevalent all over the world. There is no published report on Mycoplasma hyopneumoniae incidence in Grenadian pigs. The aim of this study was to estimate seroprevalence of antibodies for Mycoplasma hyopneumoniae in non vaccinated pigs in Grenada. Sera were collected randomly from 459 pigs of all ages from all six parishes of Grenada. Sera were tested for antibodies to Mycoplasma hyopneumoniae using an indirect Enzyme Linked Immunosorbant Assay (ELISA) kit. Antibodies to Mycoplasma hyopneumoniae were found in 8.71% (95% CI: 0.0644 to 0.1167) pigs. The greatest percent of positives (62.5%) (95% CI: 0.4699 to 0.7582) were in youngest group 22.5% (95% CI: 0.1211 to 0.3771) in >2 year. Positive females were overrepresented compared to males by 3:1. This is the first report on the sero-prevalence of Mycoplasma hyopneumoniae in pigs from Grenada, West Indies.

Highlights

Mycoplasma hyopneumoniae is the causative agent of Porcine Enzootic Pneumonia, and is a primary contributor to the porcine respiratory disease complex [1]

Summary

Introduction

Mycoplasma hyopneumoniae is the causative agent of Porcine Enzootic Pneumonia, and is a primary contributor to the porcine respiratory disease complex [1]. Enzootic pneumonia in pigs is a highly contagious and chronic disease [2]. M. hyopneumoniae is primarily a problem of grow-finish pigs, disease is reported in all age groups [13] [14]. This pathogen is considered a major economic concern within the swine industry because it causes a significant reduction in the weight of growing pigs [15]. Porcine enzootic pneumonia is endemic worldwide and M. hyopneumoniae is present in almost every pig herd [16]. This paper looks at the current status of M. hyopneumoniae within the pig farming industry in Grenada, West Indies with an aim to establish a current baseline of the prevalence of this pathogen
