Effects of serotonin, adrenaline and other vasoactive drugs on the branchial blood vessels of the Antarctic fish Pagothenia borchgrevinki

Myography and an isolated, perfused gill arch preparation were used to investigate the actions of drugs on the gill vasculature of an Antarctic teleost fish, Pagothenia borchgrevinki. Serotonin produced a dose-dependent vasoconstriction of the afferant branchial arteries, the gill arch and the efferent branchial arteries, and was the most potent vasoconstrictor tested. Acetylcholine, at concentrations exceeding 1 × 10^-6M, vasoconstricted the gill arch, but had a negligible effect on the branchial arteries. The responses to adrenaline, with and without the -adrenergic blocking drug, sotalol and the effects of the -adrenergic agonist drug isoprenaline indicated the presence of both -adrenergic and -adrenergic receptors in the gill vasculature, with the vasoconstrictory action of the former predominating in the efferent vasculature. Angiotensin II was without effect in either preparation. The results are a further demonstration of the dominance of vasoconstrictory responses in the control of gill cular resistance in P. borchgrevinki: which has been associated previously with the sub-zero temperatures at which the animals are found.     

Potential exposure to Australian bat lyssavirus is unlikely to prevent future bat handling among adults in South East Queensland

Despite ongoing public health messages about the risks associated with bat contact, the number of potential exposures to Australian bat lyssavirus (ABLV) due to intentional handling by members of the general public in Queensland has remained high. We sought to better understand the reasons for intentional handling among these members of the public who reported their potential exposure to inform future public health messages. We interviewed adults who resided in a defined geographic area in South East Queensland and notified potential exposure to ABLV due to intentional handling of bats by telephone between 1 January 2012 and 31 December 2013. The participation rate was 54%. Adults who reported they had intentionally handled bats in South East Queensland indicated high levels of knowledge and perception of a moderately high risk associated with bats with overall low intentions to handle bats in the future. However, substantial proportions of people would attempt to handle bats again in some circumstances, particularly to protect their children or pets. Fifty‐two percent indicated that they would handle a bat if a child was about to pick up or touch a live bat, and 49% would intervene if a pet was interacting with a bat. Future public health communications should recognize the situations in which even people with highrisk perceptions of bats will attempt to handle them. Public health messages currently focus on avoidance of bats in all circumstances and recommend calling in a trained vaccinated handler, but messaging directed at adults for circumstances where children or pets may be potentially exposed should provide safe immediate management options.

Herd-specific and age-specific seroprevalence of Neospora caninum in 14 British dairy herds.

All the cattle in 14 dairy herds in England were tested for Neospora caninum-specific antibodies with a commercial ELISA. Three of the herds had had sporadic abortions, eight had had endemic abortions and three had had epidemic abortions associated with N caninum before the study. Of 4295 cattle tested, 17.1 per cent were seropositive and the herd-specific prevalence ranged from 7.3 per cent to 44.8 per cent. No significant effect of either herd size (P = 0.988), endemic (P = 0.869) or epidemic (P = 0.138) patterns of abortion on herd-specific prevalence was found by using logistic regression analysis. There was no evidence in any herd of a significant increase in prevalence with age; the prevalence in seven-to 12-month-old cattle was not significantly different (P > 0.400) from the prevalence in older cattle, except that there was a significantly lower prevalence (P = 0.017) in 13-to 24-month-old cattle. The results of this study are consistent with vertical transmission being the major route of N caninum transmission in these herds.
