    Abstract: The contamination of foodstuffs, additives, cosmetics, pharmaceuticals and the like by undesirable micro-organisms is threat to public health. On occasion, the level of bacteria that conventional testing techniques are designed to look for is so low that the test result for the bacterium is “negative”. However, the bacterium although present in un-detectably small amounts may multiply under the right conditions and given the shelf life of the product, may be able to recover to an extent whereby public health is threatened. This problem is alleviated by the provision of micro-organism testing apparatus comprising (a) an incubator, and (b) a multi-compartment resealable container provided with or adapted to receive a growth medium in one compartment and having a growth medium additive in another compartment, the compartments being separated by a barrier whose removal or puncture will expose the medium to the additive.

    Abstract translation: 不良微生物对食品，添加剂，化妆品，药​​品等的污染对公众健康构成威胁。 有时，传统测试技术设计的细菌水平很低，使得细菌的检测结果为“阴性”。 然而，细菌虽然以不可检测的少量存在，但可以在合适的条件下繁殖并给予产品的保存期限，可以恢复到公共卫生受到威胁的程度。 通过提供微生物测试装置来减轻这个问题，微生物测试装置包括（a）培养箱和（b）多室可重新密封的容器，其提供或适于在一个隔室中接收生长培养基并且在另一个隔室中具有生长培养基添加剂 隔间，隔室被隔离物隔开，其移除或穿刺将介质暴露于添加剂。

    Abstract: Methods for the diagnosis of visceral, cutaneous and canine leishmaniasis in a subject suspected of being infected with the parasitic protozoa Leishmania is disclosed. Disclosed are antibody-capture enzyme-linked immunosorbent assays (ELISAs) for the detection of antibodies to Leishmania parasite soluble antigens and antigen-capture ELISAs for the detection of Leishmania parasite soluble antigens in host samples. Also disclosed are immunodiagnostic kits for the detection of Leishmania parasite circulating antigens or IgM and IgG antibodies in a sample from subject having visceral, cutaneous or canine leishmaniasis. In these methods and kits, detection may be done photometrically or visually. The methods and kits also allow the visualization of Leishmania amastigotes or promastigotes in a sample.

    Abstract: A method is provided for screening microorganisms having a selectable characteristic comprising: (a) providing a growth chamber capable of forming a plurality of discrete compartments, said compartments comprising a barrier which inhibits the diffusion of metabolites or nutrients between said compartments within said growth chamber; (b) preparing a growth medium which, by its lack of or addition of one or more metabolites or nutrients, preferentially facilitates growth of microorganisms exhibiting said selectable characteristic from microorganisms which do not exhibit said selectable characteristic; (c) inoculating said growth medium with a plurality of microorganisms, a portion of which comprise said selectable characteristic; (d) placing said inoculated growth medium into said growth chamber so as to randomly disperse said microorganisms among discrete compartments in said growth chamber; and (e) incubating said growth chamber for a suitable time and under suitable conditions to obtain a detectable disparity of growth between microorganisms having said selectable characteristic and microorganisms lacking said selectable characteristic.
