Pseudomonas aeruginosa is a bacterium that occurs commonly in the environment - water, soild, feces, skin, mucolous membranes. From there it can get into the udder, for example when applying intramammary preparations during drying off, if the procedure is not performed correctly. This masititis is relatively rare, however in its acute form it can be fatal.
Clinical symptoms appear suddenly - swelling of the mammary gland, pain, increased but also decreased body temperature and general symptoms associated with toxemia (general poisoning of the body).
The secretion of the mammary gland is watery, bulish, later bloody or chocolate-colored, smelly.
Severe cases can result in the death of the animal. The disease can also develop into a chronic form with occasional acute flare-ups. With an early and correct diagnosis, there is some hope that the dairy cow will recover, and therefor it is necessary to culrivate and examine antibiotics sensibility as soon as possible. Only according to the clinical course we cannot distinguish the difference between peudomonad mastitis and mastitis caused by enterobacteria (E. coli, Klebsiella sp., Etc.)
Pseudomonas aeruginosa has a high degree of natural antibiotic resistance, so rapid testing is essential.
A high standard of hygiene and aseptic procedures for intramammary applications are required for disease prevention.
On the PM test, Pseudomonas aeruginosa grows in the sector for gram-negative rods ( it is a gram-negative rod), in large white (but sometimes also yellowish or green), flat colonies. Some, but not all, strains of Pseudomonas aeruginosa produce pigments, so in addition to white colonies, we can rarely see coloured ones.
For pseudomonadal infection, confirmation of MALDI-TOF or another bacteriological method and, above all, rapid examination for antibiotic sensibility is appropriate. All examinations will be performed in our cooperating laboratory.
