[The occurrence of Prototheca in fecal samples of cattle]
Abstract:
Prototheca spp. were detected in 146 (48.7%) of culturally examined fecal samples of cattle, using the selective medium, developed by Pore (1973). 114 fecal samples (78.1%) contained a monoculture of Prototheca (P.) zopfii, while 10 fecal samples (6.8%) contained a monoculture of P. moriformis. In further 22 fecal samples (15.1%) a mixed culture of P. zopfii and P. moriformis was detected. The results of this study permit to conclude that cattle can harbour and shed Prototheca spp. in variable frequency.
Insights
Prototheca species were found in nearly half of cattle fecal samples. This indicates cattle can carry and shed these algae, with Prototheca zopfii being the most common type identified.
Area of Science:
- Veterinary Microbiology
- Algal Research
- Bovine Health
Background:
- Prototheca species are ubiquitous, non-photosynthetic algae.
- These organisms have been implicated in bovine mastitis and other infections.
- Understanding the prevalence of Prototheca in cattle is crucial for herd health management.
Purpose of the Study:
- To determine the prevalence of Prototheca species in fecal samples from cattle.
- To identify the specific species of Prototheca shed by cattle.
- To assess the frequency of Prototheca shedding in a cattle population.
Main Methods:
- Selective culturing of fecal samples using a medium developed by Pore (1973).
- Microbiological examination of 146 positive samples.
- Species identification based on cultural characteristics.
Main Results:
- Prototheca spp. were detected in 146 out of 299 (48.7%) examined fecal samples.
- Prototheca zopfii was the predominant species, found in 114 samples (78.1% of positive samples).
- Prototheca moriformis was identified in 10 samples (6.8%), and mixed cultures were found in 22 samples (15.1%).
Conclusions:
- Cattle frequently harbor and shed Prototheca species in their feces.
- Prototheca zopfii is the most commonly isolated species from cattle fecal samples.
- The findings highlight the potential role of cattle as carriers of Prototheca spp.
