Mycoplasma Prevalence in Goats and Sheep from Northeastern Brazil

A study investigated contagious agalactia in flocks from Pernambuco State, Brazil. The research involved 225 goats and 63 ewes, with 288 milk samples and 100 vaginal swabs collected. PCR assays identified Mycoplasma agalactiae and Mycoplasma mycoides cluster DNA, and risk factors for infection were analyzed.

Use Cases

• Modeling disease risk factors based on breeding system (extensive vs. intensive) and production type (meat vs. dairy).
• Analyzing pathogen prevalence differences between species (goats vs. sheep) and sample types (milk vs. swabs).
• Studying the association between animal housing cleanliness, quarantine practices, and mycoplasmosis infection odds.

Strengths

• Sample sizes are explicitly stated: 225 goats, 63 ewes, 288 milk samples, and 100 vaginal swabs.
• Prevalence percentages are provided for each pathogen in different sample types and species.
• Risk factor analysis includes specific odds ratios (e.g., OR 6.2 for extensive breeding) and p-values.

Limitations

• Row count and column-level documentation are unknown; field semantics must be inferred after download.
• Geographic coverage is limited to the semiarid region of Pernambuco state, Brazil.
• Last update date is unknown; freshness unverified.
