The occurrence and antibiotic resistance of motile Aeromonas in livestock.
- Journal Article
Summary
This research article investigates the prevalence of motile Aeromonas species, a type of bacteria, in the faeces of various livestock (sheep, cattle, and horses) and also evaluates the resistance of these bacteria to certain antimicrobial agents.
Objective
The main aim of the study was to understand considerably the extent of occurrence of motile Aeromonas strains in otherwise clinically healthy livestock and also check their susceptibility to certain antimicrobials.
Methodology
- Rectal swabs were collected from a total of 225 animals (120 sheep, 85 cattle, and 20 horses).
- Aeromonas species were examined from these swabs using alkaline peptone water (pH 8.4) as an enrichment medium and Aeromonas Selective Agar containing 5 mg/l ampicillin as an isolating medium.
- The identification and resistance to antibiotics of motile Aeromonas strains was then conducted using Gram Negative Enteric ID panels.
Findings
- Motile Aeromonas species were found in 12 (10%) sheep, 7 (8.2%) cattle, and 1 (5%) horse.
- Of the 20 Aeromonas isolates identified, 13 were A. caviae, 6 were A.sobria, and 1 was A. hydrophila.
Implications
The presence of Aeromonas species in livestock faeces could pose a human health risk, particularly for those who have direct contact with animals likely contaminated. However, further studies are recommended to investigate the transmission dynamics of aeromonads between animals and humans.
