Scientists from the Check Republic discovered the evidence that ticks may prefer attacking people with a certain blood type. Tick, the blood-sucking parasites, can carry various bacteria, including bugs that cause the Lyme disease.
In the course of study, the researchers dropped a tiny sample of blood from blood types A, B, AB, and O onto a sterile layer of filter paper on a Petri dish in the laboratory. The analysis of the received results showed that the ticks preferred type A blood in the majority of cases — 36% of the tick chose the sample. Type B was found to be least “favorite” — only 15% of the parasite chose the respective samples.
Lead researcher Dr. Alena Zakovska says: “The presented study demonstrated that blood group might be one of the factors determining the feeding preferences of Ixodes ricinus ticks.”
A group of Turkish scientists found a link between the blood group and the risk of impotence. According to the findings of the study, men who have a blood group O suffer from erectile dysfunction much less. It is noted that about 44 % of men have this blood type.
To their study, specialists connected 350 men, followed by observations over a long period. As a result, it turned out that the owners of the O blood group suffered from problems with erection much less often than men with other blood groups.
Data show that 16 % of the cases of this dysfunction in men with the O blood group account for 42 % of cases in representatives with a second blood group.
Scientists note that at present objective conclusions are difficult to make. However, the observed four-fold difference, in their opinion, is quite significant, and it can not be completely written off for coincidence.
