Bovine mastitis due to Prototheca zopfi
Summary
Bovine mastitis caused by the alga Prototheca zopfi was misdiagnosed as Cryptococcus neoformans. This alga-induced mastitis shows resistance to common veterinary antibiotics, posing treatment challenges.
Area of Science:
- Veterinary Medicine
- Microbiology
- Animal Pathology
Background:
- Bovine mastitis is a significant economic and animal welfare concern in dairy farming.
- Accurate etiological diagnosis is crucial for effective treatment and control of mastitis.
- Algal infections, though less common, can cause persistent and difficult-to-treat mastitis.
Purpose of the Study:
- To report a case of bovine mastitis caused by Prototheca zopfi.
- To highlight the diagnostic challenge posed by misidentification of Prototheca zopfi.
- To discuss the implications of Prototheca zopfi mastitis on treatment strategies.
Main Methods:
- Case report detailing clinical presentation and diagnostic procedures.
- Microbiological culture and identification techniques.
- Review of treatment outcomes and antimicrobial resistance patterns.
Main Results:
- A case of bovine mastitis was successfully attributed to the alga Prototheca zopfi.
- The causative agent was initially misidentified as the yeast Cryptococcus neoformans.
- Protothecal mastitis exhibited resistance to standard antibiotic therapies used in veterinary practice.
Conclusions:
- Prototheca zopfi is an important, albeit uncommon, cause of bovine mastitis.
- Diagnostic errors can occur, necessitating careful microbiological evaluation.
- The resistance of Prototheca zopfi to antibiotics requires consideration of alternative treatment approaches.

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

1.5K
Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...

502
The phylum Tenericutes, which includes the single class Mollicutes, comprises bacteria that lack cell walls. The term "Mollicutes" derives from the Latin word mollis, meaning "soft." These organisms are among the smallest known and are commonly referred to as mycoplasmas due to the prominence of the genus Mycoplasma, which includes well-known human pathogens. Despite their inability to stain gram-positively (a result of their lack of cell walls), mycoplasmas are phylogenetically related to the...

Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased...

Planctomycetes are a group of morphologically distinct bacteria predominantly classified into two orders: Planctomycetales and Brocadiales. These gram-negative bacteria exhibit unique features, including division by budding and the presence of stalks or appendages. Their cells are often found in rosette arrangements, and they are notable for possessing an S-layer in their cell envelope, which is relatively uncommon among bacteria. Additionally, Planctomycetes frequently exhibit intracellular...

Coryneform bacteria are gram-positive, aerobic, nonmotile rods that exhibit irregular, club-shaped, or V-shaped arrangements. Their V-shape results from snapping division, where the inner cell wall layer forms the cross-wall, while the outer layer remains intact until it ruptures on one side, causing the daughter cells to bend away.The primary genera are Corynebacterium and Arthrobacter. Corynebacterium includes diverse species, ranging from saprophytes to pathogens like Corynebacterium...
