The kinds of Aeromonas hydrophila-2

by : Elfahry

5. Associated Foods:
A. hydrophila has frequently been found in fish and shellfish. It has also been found in market samples of red meats (beef, pork, lamb) and poultry. Since little is known about the virulence mechanisms of A. hydrophila, it is presumed that not all strains are pathogenic, given the ubiquity of the organism.

6. Relative Frequency of Disease:
The relative frequency of A. hydrophila disease in the U.S. is unknown since efforts to ascertain its true incidence have only recently been attempted. Most cases have been sporadic rather than associated with large outbreaks, but increased reports have been noted from several clinical centers.

7. Course of Disease and Complications:
On rare occasions the dysentery-like syndrome is severe and may last for several weeks.
A. hydrophila may spread throughout the body and cause a general infection in persons with impaired immune systems. Those at risk are individuals suffering from leukemia, carcinoma, and cirrhosis and those treated with immunosuppressive drugs or who are undergoing cancer chemotherapy.

8. Target Populations:
A. hydrophila can be recovered from most foods by direct plating onto a solid medium containing starch as the sole carbohydrate source and ampicillin to retard the growth of most competing microorganisms.

9. Food Analysis:
All people are believed to be susceptible to gastroenteritis, although it is most frequently observed in very young children. People with impaired immune systems or underlying malignancy are susceptible to the more severe infections.

Most cases have been sporadic, rather than associated with large outbreaks.
For information on recent outbreaks see the Morbidity and Mortality Weekly Reports from CDC.

Loci index for genome Aeromonas hydrophila
Available from the GenBank Taxonomy database, which contains the names of all organisms that are represented in the genetic databases with at least one nucleotide or protein sequence.

12. Molecular Structural Data:
None currently available.
