Serotypes M1, 3, 5, 6, 18 and 24 have all been identified as rheumatogenic, or capable of causing acute rheumatic fever (ARF), and it has been suggested that the cyclic nature of severe infection and ARF rates is a reflection of the cyclic circulation of specific rheumatogenic serotypes [1].
Phylogenetic analysis did not suggest circulation of specific KIPyV and WUPyV strains in HIV-1 positive HIV-1 positive
The circulation of this specific CCHFV lineage in Greece, especially in a region where the seroprevalence is high, together with the lack of human CCHF cases, suggests a probable antigenic, but non- or low-pathogenic character of this lineage.
Due to the current low circulation of MenC, specific antibody levels may further decrease, putting these non-immunized adults at increased risk in the (near) future if MenC returns in the community.
However, rabies still remains a public health problem in these countries because of natural circulation of bat-specific viruses (order Mononegavirales, family Rhabdoviridae, genus Lyssavirus) such as European bat lyssaviruses (EBLVs).
Previous reports have hypothesized that the circulation of genotype-specific antibodies in the human population can influence the number of infections and the dominating P1 type (13 ), but our data do not support this hypothesis.
The circulation of hantaviruses is specific predominantly to rodent species and thus correlates with the host range of the rodent reservoir.
The fetal circulation has a number of specific vascular pathways not seen in the adult (foramen ovale, sinus venosus, ductus arteriosus).
The appearance in the circulation of the cardiac-specific isozyme of troponin is indicative of damage to the myocardium, and is associated with an adverse long-term prognosis [ 32].
The evidence gathered on shallow water areas covered by fine-grained sediments (seafloor type A) imply that these regions might be affected by some kind of specific local circulation pattern, generating preferential conditions for a good preservation of the fine-grained deposits in specific, slightly lowered areas.
Incorporation of DNA testing necessitated compliance with official regulations and French "bioethics" laws: the need for a written consent from the patient/guardian and specific circulation of the prescription, sample, and results.
