Abstract: A method for the detection and/or identification of Cryptosporidium organisms in general, and one or more of C. hominis, C. parvum and C. meleagridis organisms in particular and/or nucleic acid sequences and to hybridization assay probes, helper probes, amplification primers, nucleic acid compositions, probe mixes, methods and kits useful for determining the presence of Cryptosporidium organisms in general, and one or more of C. hominis, C. parvum and C. meleagridis organisms in particular, in a test sample of water, faeces, food or other sample media.

Abstract: A device for isolating at least a portion of a pipe from fluid flowing therethrough. The device having a body (1) that is at least partially insertable into the pipe. An external surface of the body is adapted to abut with an inner surface of the pipe to substantially prevent fluid flowing therethrough. At least one valve element (10) is arranged within the body (1) and is selectively openable and closable to permit fluid to flow through the body to facilitate removal of the body from the pipe.

Abstract: There is disclosed an attachment device for attaching a pipe cleaning tool to a rotary motion facilitation device. The pipe cleaning tool comprises an elongate member adapted to be received by the rotary motion facilitation device. The attachment device comprises a connecting element that is positionable to connect the elongate member to said rotary motion facilitation device such that rotary motion can be transferred from the rotary motion facilitation device to the pipe cleaning tool. A retainer element is mountable to the rotary motion facilitation device to enclose at least a portion of the connecting element to retain the connecting element in position.

Abstract: The invention provides a method for the removal of biological species, such as Cryptosporidium, from water using aluminum based media which contains surface Al—OH groups.

Abstract: A host-cell free method for culturing Cryptosporidium comprising the step of introducing Cryptosporidium, at a first lifecycle stage, into a host-cell free medium under conditions which enable the Cryptosporidium to progress to a second lifecycle stage.

Abstract: A method of producing IgG1 subclass antibodies reactive to the surface of Crystosporidium oocysts, the method comprising: (a) separating at least a protion of the Cryptosporidium oocyst wall from the internal sporozoites to form an oocyst-wall preparation; (b) treating the separated oocyst-wall preparation so as to obtain an oocyst antigen preparation capable of eliciting a detectable IgG1 immune response in an animal to the surface of the oocyst; (c) immunizing an animal with the oocyst antigen preparation so as to elicit an IgG1 immune response in the animal; and (d) obtaining from the animal IgG1 antibodies reactive to the surface of Cryptosporidium oocysts. IgG1 antibodies reactive to the surface of Cryptosporidium oocysts.
