Abstract
A high morbidity and mortality of goats has been
observed in the central area of Veracruz, Mexico, where goat production is
practiced. The clinical signs showed by these goats may be related to
mycoplasmosis, a highly contagious disease that causes serious economic losses.
Thus, our objective was to evaluate the seroprevalence of
Mycoplasma mycoides subspecies
mycoides (Mmm) using a competitive ELISA (c-ELISA) and to assess risk
factors associated with seropositivity. The seroprevalence of 556 goats sampled
in random was 11.2%, the frequency by local municipality was 64.3%, and 25.3%
per animal small production farm (SPF). The identified risk factors were
associated with breeding in the municipalities of Coacoatzintla (OR=14.2; 95%CI:
6.9-29.5), Villa Aldama (OR=4.9; 95%CI:2.5–9.5) and Chiconquiaco (OR=7.71;
95%CI:3.6–16.47); the crossbreeding phenotype (OR=1.78; 95%CI:1.05–3.04), stage
of suckling goat kids (OR=2.87; 95%CI:1.64–5.03), mobilization of animals (OR=4;
95%CI:2.33–6.88), semi intensive production system (OR=2.51; 95%CI:1.24–5.07)
and coexistence with cattle (OR=3.28; 95%CI:1.53–7.02). Possible protective
factors were associated with drink water from stream (OR=0.54; 95%CI:
0.29–0.98), well water (OR=0.11; 95% CI:0.01–0.82), Saanen breed (OR=0.39;
95%CI:0.19–0.8), purchased animals (OR=0.47; 95%CI:0.24–0.93) and the extensive
system of production (OR=0.13; 95%CI:0.03–0.55). In conclusion, this study
showed that the overall seroprevalence of Mmm in goats has a low general
distribution, moderated by animal small production farms and high by
municipality, in the central region of Veracruz, Mexico. Considering these
results is required to perform further studies by use of molecular techniques
for the precise identification of the etiological agent.
