[0002] The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Mainly regarded as a civic nuisance due to their droppings, pigeons have long been criticized for defacing the properties and monuments which lowers the aesthetic aspects of the building along with increasing the cost of maintenance manifolds. In addition, their dried droppings are the source of spread of many deadly bacterial and fungal diseases and infections, which has a direct impact on human welfare.
[0004] Various devices have been used in the past to prevent pigeons from resting on the buildings and other areas where they are not wanted. Usually, the birds adapt quickly to the presence of such devices and render them useless for their intended function.
[0005] Also, various compositions have been prepared and used to prevent pigeons from resting on the buildings and other locations. Unfortunately, majority of such compositions themselves render the buildings and other locations discolored resulting in economic loss.
[0006] The present invention satisfies the requirements and overcomes the deficiencies generally found in the conventional pigeon repellent compositions.

[0069] The Pigeon repellent composition is effective in repelling pigeons within 10 days when sprayed daily. The pigeon droppings were observed daily before and after spraying and it has been observed that the number of dropping decreased day by day and no droppings were observed from day 9th onwards indicating that pigeons stopped coming to the site that was sprayed with the Pigeon repellent composition.
[0070] Example 4: Anti-bacterial activity of the Pigeon repellent composition
[0071] The method used to determine the anti-bacterial activity of the Pigeon repellent is based on the inoculation of a standardized liquid culture of the test strain in a dilution series of the tested antibacterial for which the MIC is determined. The first concentration in the dilution series at which no visual growth can be determined is then considered as the MIC. Graph was plotted with respect to Log concentration of the test product and Probit of mortality for calculation of LC50 against bacterial strains Escherichia coli (ATCC 8739) and Salmonella typhimurium (ATCC 23564).
[0072] Procedure: The working culture of bacteria (E.coli and S. typhimurium) was prepared. Stock solution of the test organism was prepared as to obtain a count of at least 5 x 105 cfu per ml by using densitometer. The concentration of Pigeon Repellent composition taken was 100 mg/ml to 10 mg/ml, prepared in Soybean Casein Digest Medium (SCDM). After preparation of all the tubes, a 100µl of the adjusted culture (approx.105cfu/ml) was added in to each tube and all the tubes were incubated for 24 hours. After incubation, all the tubes were visually observed for growth of microorganisms. The effectiveness of the antibacterial activity of Pigeon Repellent composition was recorded in terms of MIC. The concentration at which the growth of test organisms is inhibited was considered as the MIC of composition. Graph was plotted with respect to Log concentration of the test product and Probit of mortality.
[0073] The antibacterial activity of Pigeon Repellent composition was calculated in terms of LC50 against Escherichia coli and Salmonella typhimurium and resulted in LC50 of 47.86 mg/ml against Escherichia coli and 50.11 mg/ml against Salmonella typhimurium.
[0074] Example 5: Anti-Fungal activity of the Pigeon repellent composition
[0075] Fungal Strain Cryptococcus neoformans (NCIM 3378), Candida albicans (ATCC 10231) and Saccharomyces cerevisiae (ATCC 9763) were used to evaluate the anti-fungal activity of the Pigeon Repellent composition.
[0076] Procedure: The working culture of test organism (Cryptococcus neoformans, Candida albicans and Saccharomyces cerevisiae was prepared. Stock solution of the test organism was prepared as to obtain a count of at least 0.5-2.5 x 103 cfu per ml by using densitometer. The concentration of Pigeon Repellent composition taken was 100mg/ml to 10mg/ml. The concentration of sample was prepared in SCDM. After preparation of all the tubes, a 100µl of the adjusted culture (approx.103 cfu/ml) was added in to each tube and all the tubes were incubated for 72 hours. After incubation, all the tubes were visually observe for growth of microorganisms. The concentration at which the growth of test organisms is inhibited was considered as the MIC of product. The effectiveness of the antifungal activity of Pigeon Repellent composition was recorded in terms of MIC. Graph was plotted with respect to Log concentration of the test product and Probit of mortality.
[0077] The antifungal activity of Pigeon Repellent Composition resulted in LC50 against Cryptococcus neoformans as 50.11mg/ml, LC50 against Candida albicans as 50.11mg/ml and LC50 against Saccharomyces cerevisiae was 47.86mg/ml.
[0078] Example 6: In-vitro cytotoxicity study of the Pigeon repellent composition
[0079] To assess the cytotoxic potential of the Pigeon Repellent Composition, ‘In-vitro cytotoxicity study’ on L-929 mouse fibroblast cells was carried out. The study was conducted as per International Organization for Standardization ISO 10993-5:2009, Biological evaluation of medical devices-Part 5: Tests for in vitro.
[0080] The in-vitro cytotoxicity study specifies the incubation of cultured cells with the Pigeon Repellent composition. A preliminary study was conducted with different range of concentrations of the composition. On the outcome of preliminary study, doses for main cytotoxicity assay were selected. Negative control and positive control were prepared by using culture medium with 10% serum. Serum-supplemented DMEM cell culture media was used. Negative control used was culture Medium containing 10% FBS whereas Positive control was Liquefied Phenol at 1.6 mg/ml in culture media. The composition in four different concentrations (1mg/ml, 2mg/ml, 4mg/ml and 8mg/ml) was added onto three separate nearly 80% confluent monolayer of L-929 mouse fibroblast cells. Similarly the negative control and positive control was placed onto separate nearly 80% confluent monolayer in triplicates. All the monolayers were incubated at 37±1°C in the presence of 5±1% carbon dioxide for 24 hours. At 24 hour the monolayer of the composition, negative control and positive control were examined microscopically. 50µl of MTT solution were transferred into multi well plate. All the wells were incubated at 37±1°C in an incubator in the presence of 5 ±1 % Carbon dioxide for 2hrs.Then the MTT solution was decanted and 100µl of isopropanol (acidified) were added in each well and subsequently absorbance recorded at 570nm.
[0081] Under the condition of this study, the viability % of L929 cells treated with Pigeon Repellent composition at dose concentration 2mg/ml, came out as > 70 % when compared to its control counterpart. Therefore, the dose concentration 2mg/ml was found to be Non- Cytotoxic.
[0082] The confluency of the monolayer was recorded as (+) if present and (-) if absent. Each culture well was evaluated for Viability percent by MTT Cytotoxicity test. To calculate the reduction of viability compared to control, the following equation was used:

Where
OD570e is the absorbance of the 100% extract of test sample
OD570b is the absorbance of the control
The Lower the Viability %, the higher the cytotoxic potential of the test item. If Viability is reduced <70% of the blank, it has a cytotoxic potential.
[0083] The Pigeon Repellent composition was found to be non-cytotoxic at dose concentration of 2mg/ml when Viability % and cellular Characteristics of cells was compared with Negative control.
[0084] The foregoing examples are merely illustrative and are not to be taken as limitations upon the scope of the invention. Various changes and modifications to the disclosed embodiments will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the scope of the invention.
