Summary
# Editorial Summary As llama and alpaca breeding expands across Europe and beyond their native South American habitat, veterinarians and producers increasingly encounter bacterial infections in these species, yet clinical guidance remains fragmented because reference data are often extrapolated from cattle, sheep and horses rather than derived from camelid-specific research. Konieczny and Pomorska-Mól conducted a comprehensive literature review synthesising current knowledge on eight bacterial pathogens of significant concern—Clostridium spp., *Mycobacterium tuberculosis* complex, *Mycobacterium avium* subsp. *paratuberculosis*, Streptococcus spp., *Escherichia coli*, *Pasteurella multocida*, *Manheimia haemolytica* and *Corynebacterium pseudotuberculosis*—with particular focus on epidemiological patterns, clinical presentation and diagnostic approaches specific to llamas and alpacas. The review highlights that whilst these animals are generally considered disease-resistant, several of the pathogens examined carry zoonotic potential and merit careful attention to biosecurity protocols and diagnostic protocols; the authors emphasise that reliance on extrapolated data from other species may lead to diagnostic delays or missed infections. For practitioners managing South American camelids, this synthesis provides evidence-based context for recognising bacterial disease presentations and implementing appropriate diagnostic strategies, whilst underscoring the importance of species-specific clinical knowledge as these populations continue to expand in non-endemic regions.

Practical Takeaways
- •Veterinarians working with llamas and alpacas should recognize these eight bacterial diseases and their zoonotic potential, implementing appropriate biosecurity measures.
- •Clinical presentation and diagnostics for these conditions in SACs may differ from other species; direct reference to camelid-specific literature is essential when available.
- •Breeders and practitioners should educate themselves on disease epidemiology and clinical signs specific to their growing SAC populations, particularly in non-endemic regions.
Key Findings
- •Literature on bacterial infections in South American Camelids (llamas and alpacas) is limited, requiring veterinarians to extrapolate data from cattle, sheep, and horse studies.
- •Multiple bacterial pathogens studied have zoonotic potential, making infected camelids a public health concern.
- •Review synthesizes epidemiology, clinical signs, and diagnostic approaches for eight major bacterial diseases in llamas and alpacas.
- •Growing popularity of alpaca and llama breeding in non-endemic regions necessitates increased veterinary awareness of these infections.
