Prototheca wickerhamii, a ubiquitous green alga devoid of chlorophyll, is commonly found in the environment but infrequently leads to opportunistic infections in humans. Even protothecosis is rare, its incidence has exhibited a notable increase over the last two decades. This surge is attributed to the widespread utilization of immuno-suppressive drugs & the rising prevalence of organ transplantation. A comprehensive review covering 115 reported human cases of protothecosis between 1964 and 2011 revealed a geographical distribution, with the majority (63%) originating from Asia, followed by Europe (18%), North America (15%), and Africa (4%).
The environmental ubiquity of P. wickerhamii, spanning soil, water, sewage, plants, and animal feces, positions it as an exogenous source of infection. The precise transmission routes of protothecosis remain elusive but may involve direct contact, ingestion, inhalation, or inoculation of the algae into the body. Among the clinical forms observed, cutaneous presentations accounted for 40%, followed by olecranon bursitis at 28%, and disseminated cases at 13%. Key risk factors associated with protothecosis included diabetes mellitus (23%), organ transplantation (19%), and HIV infection (10%). The mortality rate for protothecosis stood at 18%, primarily attributed to cases of disseminated infection.

Species:P. wickerhamii
Prototheca wickerhamii, a colorless microalga, presents a round to elliptical cell shape, measuring between 3–11 µm in diameter.
The organism features a robust outer structure known as the theca, which encapsulates internal septations. Within this theca, the microalga forms small wedge-shaped endospores. These endospores exhibit a radial arrangement and adopt a morula-like form.
P. wickerhamii engages in asexual reproduction, releasing endospores from sporangia at regular intervals of approximately 5-6 hours under optimal
The genomic analysis of P. wickerhamii reveals a rich repertoire of potential virulence factors comparable to those identified in established opportunistic fungal pathogens like Candida albicans and Trichophyton rubrum. The genome harbors genes associated with the invasion of the host and the elicitation of adaptive stress responses. Noteworthy elements include genes encoding proteases, hydrolases, phospholipases, transporters, oxidoreductases, and transcription factors, comprising approximately 6% of the total genes.
Intriguingly, a significant portion of P. wickerhamii genes align with entries in the Pathogen-Host Interaction Database, with experimentally proven roles in disease development. Furthermore, the genome encompasses genes traditionally considered potential virulence factors for Prototheca, like ATPase & malate dehydrogenase. Protothecalysin toxins, identified in the genome, may contribute to evading host macrophages through interference with phagocytosis and killing processes.
The genome sizes of P. wickerhamii strain ATCC 16529, S1, and S931 are 16.7 Mbp, 17.57 Mbp, and 17.45 Mbp, respectively. The strains S1 and S931, isolated from clinical cases of protothecosis, exhibit over 96% consistency with each other, suggesting potential adaptations to the human host environment.
Prototheca wickerhamii stands as the predominant culprit in human protothecosis, with P. zopfii, P. cutis, and P. miyajii trailing behind in frequency. The infection typically arises from direct traumatic inoculation of the alga into the skin or mucous membranes or through the inhalation or ingestion of contaminated water or soil. Notably, routine water chlorination may prove ineffective against Prototheca spp. These algae exhibit a propensity to colonize human skin, gastrointestinal, and respiratory tracts, with the skin being the primary site of protothecosis manifestation. The infection commonly presents as skin nodules, accounting for the majority of cases.
In the remaining third of cases, protothecosis may assume a disseminated form or manifest as olecranon bursitis, particularly following elbow trauma. Numerous patients with protothecosis exhibit underlying local or systemic immune defects, often identified in conjunction with topical, local, or systemic glucocorticoid treatment as a prevalent risk factor. Other immune-suppressive conditions contributing to protothecosis susceptibility include diabetes mellitus and malignancy. Severe disseminated disease has been documented in recipients of bone marrow and kidney transplants, individuals with longstanding indwelling catheters or endotracheal tubes, and, albeit rarely, AIDS patients.
The pathogenesis of P. wickerhamii involves its ability to invade host cells by producing enzymes that degrade the extracellular matrix, such as proteases, lipases, and phospholipases. This invasive strategy allows the alga to breach host defenses and establish infection. Additionally, Prototheca employs tactics to evade the host immune system, including the formation of biofilms, expression of surface antigens mimicking host structures, and secretion of immunosuppressive substances.
The human immune system mounts a multifaceted response against P. wickerhamii antigens, initiating the production of antibodies and triggering immune reactions. Recognition of P. wickerhamii antigens prompts the release of inflammatory mediators, including cytokines and chemokines. These signaling molecules are involved in recruiting and activating various immune cells, such as neutrophils, lymphocytes, macrophages, and eosinophils, directing them to the infection site.
The recruited immune cells employ diverse strategies to combat P. wickerhamii. Phagocytosis and subsequent destruction of the alga by macrophages and neutrophils represent a crucial line of defense. Additionally, immune cells may collaborate to form granulomas, effectively isolating & containing the infection. Recent advancements, including the completion of the first comprehensive genome and transcriptome study of P. wickerhamii, offer valuable insights into the alga’s biology and potential virulence factors.
Prototheca wickerhamii, a chlorophyll-lacking green algae, poses the potential for opportunistic infections in humans, a condition known as protothecosis. The clinical manifestations of protothecosis manifest diversely and are categorized into three primary forms: cutaneous, olecranon bursitis, and disseminated or systemic presentations.
Cutaneous protothecosis stands out as the most prevalent form, typically initiating on the skin following minor injuries or surgical procedures. It gives rise to nodules, ulcers, or plaques, often located on the hands, elbows, or feet. The lesions may exhibit varying characteristics, ranging from painless to pruritic, contributing to the clinical heterogeneity of the disease.
Olecranon bursitis, although infrequent, represents another form of protothecosis impacting the bursa, a fluid-filled sac that cushions the
elbow joint. This manifestation induces symptoms like swelling, pain, and restricted mobility of the elbow. Associations with factors such as trauma, arthritis, or diabetes may contribute to the development of olecranon bursitis in affected individuals.
The most severe manifestation, disseminated or systemic protothecosis, extends its impact to multiple organs, including the eyes, brain, lungs, liver, spleen, or bones. This form can trigger a spectrum of symptoms such as fever, weight loss, weakness, uveitis, retinal detachment, ataxia, seizures, or organ failure.
Culture of Diseased Tissue: Culturing diseased tissue in Sabouraud dextrose agar (SDA) serves as a fundamental diagnostic approach for identifying Prototheca species and assessing their susceptibility to antifungal drugs. SDA provides an environment conducive to the growth of both fungi and algae, enabling the isolation and characterization of Prototheca strains from affected tissues. This method not only aids in pinpointing the specific species involved but also guides treatment decisions by determining their responsiveness to antifungal medications.
Visualization of Tissue Biopsy: Microscopic examination of tissue biopsies, mainly those containing sporangia, offers valuable insights into Prototheca infections. Sporangia, the cells responsible for spore production, exhibit characteristic shapes and sizes depending on the Prototheca species. For instance, P. wickerhamii is distinguished by wedge-shaped sporangiospores arranged radially. Staining techniques such as hematoxylin/eosin, GMS, or PAS enhance the visibility of sporangia and sporangiospores, facilitating precise identification of Prototheca species in affected tissues.
Cytology of Rectal Scrapings: In veterinary diagnostics, particularly for dogs and cats with suspected protothecosis-related chronic enteropathy or large bowel diarrhea, cytology of rectal scrapings emerges as a valuable diagnostic test. This procedure involves collecting cells from the rectal lining using a swab or spatula to detect the presence of Prototheca in rectal scrapings, which aids in confirming the diagnosis and tailoring appropriate treatment strategies.
ELISA for Antibody Detection: Enzyme-linked immunosorbent Assay (ELISA) stands as a blood test pivotal in confirming the diagnosis of protothecosis and monitoring treatment response. By measuring the antibody levels specific to Prototheca, ELISA provides a quantitative assessment of the immune system’s response to the infection. This serological test enhances diagnostic accuracy.
Individuals should steer clear of potential sources of P. wickerhamii, such as stagnant water, mud, or decomposing organic matter. Vigilance in recognizing and avoiding these environments is a primary preventive measure.
After any contact with possible sources of P. wickerhamii, individuals must adhere to thorough handwashing practices. Using soap and water effectively removes any potential contaminants, reducing the risk of transmission through inadvertent hand-to-mouth contact.
