“…Biotype 2 is characterised by delayed assimilation of galactose and increased assimilation of amino acids in comparison to biotype 1, whilst the strains of biotype 3 are incapable of glycerol assimilation (27). P. zopfii biotype 2 has been established to be the major causative agent of mastitis in dairy cows (3,9,14,22,23,29). Genotype 1 is considered to be non-pathogenic (12).…”

“…In Serbia, protothecal mastitis has been first diagnosed in 2006 on a Holstein-Friesian dairy farm in Vojvodina (20). Isolation of P. blaschkeae and P. wickerhamii has also been reported; however, the organisms are considered rare causal agents of bovine mastitis (7,14,29).…”

“…Throughout the past few years, substantial increase in incidence of P. zopfii mastitis has been reported all over the world (3,9,10,16,26,29,31). Since 2006, P. zopfii has been isolated from milk on four dairy farms in the regions of Vojvodina and Central Serbia; however, its much wider prevalence is suspected in some regions of Serbia even though it has not yet been isolated.…”

Increased incidence of protothecal mastitis has been recorded in several countries in the past ten years. The main goal of this article is to draw the attention of scientific and professional community to the emerging issue of mammary protothecosis. The article collates currently known facts about infection reservoirs, predisposing factors for the development of mastitis, clinical manifestations of the disease, and potential transmission routes within the herd as well as the measures for control and eradication. We would like to point out that identification of protothecal mastitis on a dairy farm is associated with a range of problems. Early detection of infected animals can be difficult because of predominantly subclinical course of early-stage infection, which easily spreads between cows via the milking system. Spontaneous recovery has not been recorded and infected cows typically develop chronic mastitis with granulomatous infiltration and progressive loss of functional parenchyma of the mammary gland. Substantial economic losses and health damages associated with mammary protothecosis strongly emphasise the need for developing effective prevention strategies aimed at control of the infection.

“…Povidone iodine is generally used in pre-and post-dipping antisepsis of mammary glands, and was found to be effective at 0.39 to 3.13 µg/ml (more than 0.313%) in this study. Salerno et al also reported that a low concentration of sodium hypochlorite (0.15625%) and iodine (0.625%) is effective against P. zopfii [7].…”

In vitro Algaecide Effect of Disinfectants on Prototheca zopfii Genotypes 1 and 2

et al. 2011

ABSTRACT. Bovine mastitis due to Prototheca zopfii leads to reduced milk production and is difficult to cure. Therefore, prevention is the best approach and this is best achieved through the use of effective disinfectants. The aim of this study was to evaluate the in vitro algaecide efficacy of conventional disinfectants against strains of P. zopfii genotype 1 and 2. The minimal algaecide concentration (MAC) of alkyldiaminoethylglycine hydrochloride, chlorhexidine, dioxide chlorine, povidone iodine and sodium hypochlorous acid against 10 isolates and the type strain (SAG2063 T ) of P. zopfii genotype 1 as well as 10 isolates and the type strain (SAG2021 T ) of P. zopfii genotype 2 were examined using the micro dilution method. This in vitro study indicated that alkyldiaminoethylglycine hydrochloride, chlorhexidine, povidone iodine and sodium hypochlorous acid, but not dioxide chlorine, are effective against both genotypes of P. zopfii.

In vitro algicidal effect of guanidine on Prototheca zopfii genotype 2 strains isolated from clinical and subclinical bovine mastitis

Prototheca zopfii genotype 2 is an opportunistic pathogen of bovine mastitis. To date, no effective therapies against protothecal mastitis have been developed. The in vitro algicidal effect of guanidine on 75 P. zopfii genotype 2 strains isolated from cows revealed that all of the isolates were susceptible to the compound at low concentrations, which indicates that guanidine may be used as an antiseptic/disinfectant for dairy milking equipment, in pre- and postdipping solutions, and as a chemical dry therapy or an intramammary therapy. This study describes the in vitro algicidal effect of guanidine on P. zopfii for the first time.
