The pejerrey Odontesthes bonariensis is the most important freshwater fish of Argentina central region. The present study was conducted to describe the seasonal variation of parasitism in O. bonariensis from La Viña reservoir (31º 17'S, 65º 01'W), located in the province of Córdoba, Argentina. Between years 1999 and 2002, 573 fishes were caught, and their parasite infection and relative weight (Wr) were assesed. Three parasites were found, Lernaea cyprinacea (Crustacea), Contracaecum spp. larvae (Nematoda) and Cangatiella macdonaghi (Cestoda). Overall, Contracaecum spp. prevalence and intensity were very low. Lernaea cyprinacea and Cangatiella macdonaghi prevalences increased during summer and spring (P < 0.01), respectively. Lernaea cyprinacea infection showed also seasonal differences in intensity (P < 0.05), as well as C. macdonaghi regarding parasites density (P < 0.01). Cangatiella macdonaghi average parasites density was 32.0 (±22.5) cestodes per cm³ of digestive content. No association between parasitism and fish relative weight was found. Besides the seasonality variations observed, the parasite burden found did not compromise fish body condition.

Various studies in ecology have shown the relationship between body condition and parasitic loads in nonhuman primates, however, little information is available regarding prosimians such as lemurs.  In this study, the synergistic effect of parasite infection and socio-ecological factors on the body condition of Microcebus rufus in the family Cheirogaleidae was analyzed in Ranomafana National Park in southeastern Madagascar.  This lemur species is characterized by its ability to adapt to different types of forest, and by seasonal fattening.  Based on the factors considered, this species is, therefore, a good model for the study of body condition and ecology of infectious diseases in lemurs. Floatation and direct observation techniques were used for examination of parasite infection.  Two indices considering body condition were analyzed: volume index (VI) and condition index (CI), the residual between the mass observed and the corrected mass.  The generalized linear mixed model (GLMM) was used to model the synergistic effect of parasite infections and socio-ecological factors on variation in body condition, with the identity of individuals used as a random factor.  We identified five species of helminths, one species of protist, and one species of lice which infected the 204 mouse lemurs captured.  There was a sexual difference for all measures of the parasite infection.  The more parasite species an individual was infected with, the smaller was its body size according to the Volume Index that reflects deposits of subcutaneous fat.  Individuals with more positive Condition Index values, particularly females, excreted more parasite eggs or oocyst in their faecal matter.  The results suggest that an individual’s body condition constitutes an indicator of risk of parasite infection and transmission.

SUMMARYBlood parasites such as haemogregarines and haemosporidians have been identified in almost all groups of vertebrates and may cause serious damages to their hosts. However, very little is known about biodiversity of these parasites and their effects on some groups of reptiles such as terrapins. Moreover, the information on virulence from blood parasites mixed infection is largely unknown in reptiles. With this aim, we investigated for the first time the prevalence and genetic diversity of blood parasites from one genus of haemoparasitic aplicomplexan (Hepatozoon) in two populations of Spanish terrapins (Mauremys leprosa), a semi-aquatic turtle from southwestern Europe with a vulnerable conservation status. We also examined the association between mixed blood parasite infection and indicators of health of terrapins (body condition, haematocrit values and immune response). Blood parasite infection with Hepatozoon spp was detected in 46·4% of 140 examined terrapins. The prevalence of blood parasites infection differed between populations. We found two different lineages of blood parasite, which have not been found in previous studies. Of the turtles with infection, 5·7% harboured mixed infection by the two lineages. There was no difference in body condition between uninfected, single-infected and mixed-infected turtles, but mixed-infected individuals had the lowest values of haematocrit, thus revealing the negative effects of blood parasite mixed infections. Immune response varied among terrapins with different infection status, where mixed infected individuals had higher immune response than uninfected or single-infected terrapins.

Zusammenfassung Ziel der Studie war, den Energiebedarf von Warmblutfohlen zu überprüfen, die durch einen Betriebswechsel beim Absetzen erhöhtem Stress ausgesetzt sind. Material und Methoden: Neun Hengstfohlen, die als Absetzer von verschiedenen Züchtern gekauft und gemeinsam aufgestallt wurden, nahmen an der Studie vom Absetzen im Alter von etwa 6 Monaten bis zu einem Alter von etwa 1 Jahr teil. Das Absetzen erfolgte im heimischen Betrieb oder nach gemeinsamem Transport von Stute und Fohlen bei Ankunft im neuen Bestand. Die Fohlen erhielten Heulage (später erster Schnitt), Hafer und Fohlenaufzuchtfutter. Um eine individuelle Kraftfutterzuteilung zu ermöglichen, wurden die Fohlen zweimal täglich separat angebunden. Erhoben wurden die Gesamtaufnahme der Heulage aller Fohlen gemeinsam pro Tag, die tägliche individuelle Kraftfutteraufnahme sowie in 4-wöchigen Abständen Körpermasse und Body Condition Score (BCS). Ergebnisse: Die tägliche Energieaufnahme der Fohlen betrug 74 MJ verdauliche Energie (68 MJ umsetzbare Energie) pro Tier. Die Fohlen wurden mit vergleichsweise niedrigem BCS von 4,2 ± 0,4 (Skala von 1 bis 9) und einer durchschnittlichen Körpermasse von 285 ± 30 kg aufgestallt. Sie erreichten am Ende der Studie im Alter von 319 ± 22 Tagen eine Körpermasse von 326 ± 24 kg und einen BCS von 4,2 ± 0,4. Die Energieaufnahme der Fohlen war höher und ihre Gewichtsentwicklung langsamer als in einer parallel laufenden Studie mit Fohlen, die im Gestüt geboren und aufgewachsen und dementsprechend beim Absetzen weniger Stress ausgesetzt waren. Schlussfolgerung und klinische Relevanz: Fohlen mit relativ niedriger Körpermasse und BCS und erheblichem Stress zum Zeitpunkt des Absetzens benötigen deutlich mehr Energie als Fohlen, die beim Absetzen in ihrer gewohnten Umgebung verbleiben und dadurch weniger Stressoren unterliegen.
