Parasite diversity associated with African penguins (Spheniscus demersus) and the effect of host and environmental factors

The African penguin (Spheniscus demersus) is a critically endangered species endemic to southern Africa. Limited information is available on the parasite diversity associated with the species in natural settings. This study explores the diversity and incidence of parasites associated with African penguins and their nests, and records the effect of host and environmental factors on parasite infestation. Ecto-, haemo- and helminth parasites were recorded from 210 adult birds, 583 chicks and 628 nests across five colonies (two mainland and three islands) along the south-western coast of South Africa, in 2016 and 2017. Mean nest density (total and active nests) and climate variables (temperature and precipitation) were obtained for each colony. Parapsyllus humboldti was the most abundant and prevalent ectoparasite on penguins and in nests (69.10 and 57.80%, respectively), while Piroplasmorida/Haemospororida (33.51%) and Cardiocephaloides spp. (56.17%) were the most prevalent haemo- and helminth parasites of penguins, respectively. In general parasite abundance and prevalence was significantly affected by penguin age (chicks vs adults), location (mainland vs islands), nest density (total and active nests) and season (spring vs autumn/winter). It is concluded that parasite infestations are structured and that penguin chicks at mainland colonies are more susceptible to parasite infestations during spring.

“…Despite the fact that the morphogenetic diapause is to be seen especially in larvae, nymphs and females in their delayed moulting and egg-laying (Guirgis, 1971;Hafez et al, 1972;Dusbibek, 1985a,b), there is no reason to doubt that the males are also subject to a morphogenetic diapause in the winter period.…”

A very close negative correlation has been demonstrated between the assembly pheromone response and locomotor activity in Argas (Persicargas) persicus (Oken). The daily rhythm of the activity of ticks in constant darkness showed alternation of diurnal assembly and nocturnal locomotor activity in regular circadian oscillations, but the intensity of the locomotor activity gradually decreased. The tendency for the period of the circadian oscillation to be longer and for the active phase of the rhythm to shift to the daytime hours occurred in ticks of the Azerbaijan population and unengorged ticks of the Czechoslovak laboratory population. This was not so in the engorged males from Czechoslovak population. The periodicity in the alternation of active and passive phases and the number of active ticks grew progressively in relation to increasing temperature. The presence of females increased the locomotor activity of males.

Specimens were cleared in lactophenol, mounted and identified according to Baker et al (1956), Baker and Wharton (1959), Madbouly (1961), Krantz (1970), Guirgis (1971), McDaniel (1979) and Manuel (1981. Some of the recorded ectoparasites were photographed using Leica Wild MPS32 photo microscope.…”

Nesting cattle egrets are considered nuisances when their breeding colonies are near structures used by humus due to noise, odour, spoiling the environment and concern over health hazards. Cattle egrets play an important role in disseminating many pathogenic microorganisms , viral, bacterial, rickettsial and parasites to domestic birds, animals and man. Ectoparasitic infection is one of the most important parasitic diseases of birds because they are not markedly host specific which makes infected foreign birds potentially dangerous carriers to other habitats. These ectoparasites may also be mechanical or biological vectors to the more serious viral and bacterial pathogens. So, this work aimed to study the ectoparasitic fauna of nesting cattle egrets at Kafr El-Sheikh city to elucidate their possible role of transmission of such parasites and infectious organisms to domestic birds and mammals. In the present study, a total of 81 adult cattle egrets were captured from KafrEl-Sheikh city and examined for ectoparasitic infection during the period from June to September 2006. Results revealed that Ectoparasites Of Nesting Cattle Egret Bubulcus Ibis L ...
