Hypothesis
To better understand the epidemiology of M. caprae, we spoligotyped 791 animal isolates.
Conclusion
M. caprae infection is widespread in Spain, affecting various domestic and wild animal species, and is primarily driven by infections in goats.
Supporting Evidence
- M. caprae represents 7.4% of all M. tuberculosis complex isolates from domestic and wild animals in Spain.
- Seventy-five of the 197 outbreaks (38.1%) involved goats.
- The proportion of M. caprae isolated from bovine samples has increased consistently during 2004–2009.
- M. caprae causes 0.3% of the cases of human tuberculosis in Spain.
Takeaway
This study found that a germ called M. caprae makes animals sick in Spain, especially goats, and it can also affect humans.
Methodology
The study involved spoligotyping 791 M. caprae isolates from various animal species collected from 1992 to 2009.
Limitations
The study is limited to data collected from Spain and may not represent the global situation.
Participant Demographics
The isolates were from domestic goats, sheep, cattle, domestic pigs, wild boars, red deer, and a fox.
