Definitions

  • the invention relates to a disinfectant containing a special combination of biocidal phenols and optionally phenol derivatives and a keratolytic.
  • the disinfectant is particularly suitable for controlling parasitic protozoa including their permanent forms.
  • Such disinfectants have e.g. particular importance in the control of coccidiosis in farm animals.
  • Eimeria tenella is the protozoan agent of poultry coccidiosis, a disease that has become an economically significant problem with the intensive keeping of chicks and chickens.
  • the infection of the animals begins after the uptake of sporulated OO cysts, which are carriers of the infectious unicellular sporozoites.
  • the sporozoites colonize intestinal cells in the protection of millions of times the multiplication of parasite stages takes place.
  • the pathology of a coccidiosis disease includes bloody diarrhea, which can cause great economic damage through reduced food intake and weight loss of chickens.
  • the chemotherapeutic treatment is carried out since 1970, especially with the polyether ionophores monensin, narasin, salinomycin and lasalocid.
  • the emergence of drug resistance is considered the biggest problem of the chemotherapeutic treatment.
  • the first sign of a resistance development is often the renewed increase in oocyst excretion.
  • Eimeria permanent stages the so-called oocysts, deposited with the feces of the animals and can persist along with fecal residues and feed components of floor coverings, wall surfaces, in wall cracks and holding devices and trigger new infections in animals used for a long period of time as a constant source of infection.
  • Eimeria oocysts can be infectious for up to one year after excretion. During this period, the carryover of oocysts by persons or animals into neighboring poultry houses is an additional burden.
  • Eimeria tenella oocysts have a size of 24.5-18.3 ⁇ m and are formed millions of times in the intestinal cells of infected animals following the asexual multiplication cycles.
  • a female Macrogamont is fertilized by a male microgamete and forms the zygote, which surrounds itself with two typical layers: a smooth outer layer, which forms after fusion of the WFI ("wall forming body I) and an inner layer, which after fusion of the Forming body WFII ("wall forming body II) is created.
  • WFI wall forming body I
  • WFII wall forming body II
  • sporulation begins: from the undifferentiated sporonts, four sporocysts, each containing two sporozoites, are formed via a reduction division. The sporulation lasts for Eimeria tenel- Ia usually 2-3 days. Only after graduation is the oocyst infectious.
  • both oocyst walls are of a marked biochemical-physiological resistance and provide an effective protective barrier to the survival of parasitic germs outdoors.
  • the outer oocyst wall is composed of phospholipids, long-chain alcohols and triglicerides
  • the inner layer consists of glycoproteins, which are stabilized by disulfide bridges.
  • the major 12-14 kDa oocyst wall protein contains serine, tyrosine and threonine amino acids and is linked to carbohydrates. These proteins give the oocyst great structural stability against heat or cold.
  • the lipids of the outer layer cause the high chemical resistance.
  • oocysts are killed in the laboratory at temperatures of 60-100 0 C in a few minutes, but the disinfecting effect of hot water under practical conditions in the barn is usually low because the water on the stable floor cools down too quickly. Even with high-pressure cleaning only a partial disinfection is achieved at low exposure times. Even against cold, the oocysts have a considerable resistance. Even after freezing at -25 ° C for 14 days, Eimeria oocysts survive and remain infectious. Drying achieves some degree of damage, but the method of disinfection has proven to be less reliable.
  • Eimeria oocysts are 100 times more resistant than bacteria. Even with con- concentrations of> 5% and an exposure time of 120 min, the infectivity of the oocysts is not lost. Occasionally ammonia (NH 3 ) is successfully used in Eastern European countries with a contact time of 24 hours, but at the same time the odor nuisance of an ammonia-saturated atmosphere is very high.
  • NH 3 ammonia
  • Ethanol (70-90%) and formaldehyde have no practical effect on the resistant oocysts of Eimeria species.
  • WO 94/17661 describes a disinfectant with parasiticidal activity which contains one or more phenols in combination with keratolytically active organic acids, ethylene glycol dialkyl ethers and sodium or potassium alkyl sulfonates or sulfates.
  • Antiparasitic disinfectants are administered in Germany according to the guidelines of the German Veterinary Society (DVG) on oocysts of Eimeria tenella in the suspension process. - A - such (lysis test) and in the infection test on chicken chicks tested for efficacy. Eimeria tenella oocysts, strain "Houghton", are considered to be particularly resistant and therefore recommended as test organisms.
