“…In fact, biological studies have been published for only 14% of approximately 60 known Amblyomma species of the Neotropical region (Onofrio et al 2006). Among the 33 Amblyomma species known to occur in Brazil, life cycle under laboratory conditions has been reported only for Amblyomma aureolatum (Rodrigues et al 2002;Pinter et al 2004), Amblyomma brasiliense (Sanches et al 2008), Amblyomma cajennense (Aragão 1936; Guglielmone et al 1992;Lopes et al 1998;Prata et al 1998;Pinter et al 2002), Amblyomma dissimile (Schumaker and Barros-Battesti 1994;Freitas et al 2004), Amblyomma dubitatum (as Amblyomma cooperi) (Labruna et al 2004;Faccini et al 2006), Amblyomma parvum (Guglielmone et al 1991), Amblyomma rotundatum (Aragão 1918;Oba and Schumaker 1984), Amblyomma tigrinum Aguirre et al 2005;Cardoso et al 2008), and Amblyomma triste (Labruna et al 2003).…”

The life cycle of Amblyomma auricularium (Acari: Ixodidae) using rabbits (Oryctolagus cuniculus) as experimental host

The life cycle of Amblyomma auricularium (Conil) is reported for the first time, using rabbits as experimental host. Developmental periods of free-living stages were observed in an incubator at 27 +/- 1 degrees C, 80 +/- 10% RH and 24 h darkness. The complete life cycle, including pre-feeding periods for each parasitic stage, ranged from 97 to 162 days. The overall sex ratio was 1.16:1 (M:F). Feeding and premolt periods, molting success, and engorgement weight of nymphs were statistically different between males and females (P < 0.01), but because their ranges overlapped, they cannot be used to predict the sex with accuracy. The potential role of rabbits as experimental hosts for rearing A. auricularium in the laboratory is discussed.

“…Randolph (2004) pointed out that these factors and others such as seasonality, search time to find a host, and mortality, influence the life cycle. In this study, a temperature of 27±1 °C and relative humidity of 80±10% were used to raise A. nodosum, since these values are used to breed most Neotropical ticks (Amblyomma parvum Aragão 1908-GUGLIELMONE et al, 1991OLEGÁRIO et al, 2011;Amblyomma aureolatum -RODRIGUES et al, 2002;Amblyomma tigrinum Koch 1844-LABRUNA et al, 2002bCARDOSO et al, 2008;Amblyomma triste -LABRUNA et al, 2003;Amblyomma cooperi Nuttal;Warburton, 1908Amblyomma incisum Neumann, 1906-SZABÓ et al, 2009 -FACCINI et al, 2010;and Amblyomma ovale -MARTINS et al, 2012). However, other values for these variables may be tested to determine the best conditions for the development of this species.…”

The natural hosts of Amblyomma nodosum in the immature stages are a variety of birds and the anteater in the adult stage. However, so far no data have been published about this tick's life cycle. To fill this gap, a record was made of its development under laboratory conditions. All the procedures were controlled in a BOD chamber set at 27±1 °C and 80±10% relative humidity and scotophase. The parasitic stages were raised on rabbits (Oryctolagus cuniculus Linnaeus, 1758), from which more than 50% of larvae and nymphs were recovered, although only a small portion performed ecdysis. The adults did not fixed on the rabbits, which suggests that the experimental conditions were unsuitable for the requirements of this species. The data obtained here indicate that A. nodosum is highly dependent on its host and environment whereas under laboratory conditions and host chosen for the study was not obtained satisfactory results and new studies with different hosts and new environmental conditions should be elaborated.Keywords: Tick, host, biology, Brazil, Amblyomma nodosum. ResumoOs hospedeiros naturais de Amblyomma nodosum, nos estágios imaturos, são uma variedade de pássaros e, na fase adulta, são os tamanduás. No entanto, até agora não há dados publicados sobre o ciclo de vida desse carrapato. Para preencher essa lacuna, um registro foi realizado sobre o desenvolvimento em condições de laboratório. Todos os procedimentos foram controlados em câmaras tipo BOD a 27±1 °C e 80±10% de umidade relativa e escotofase. As fases parasitárias foram desenvolvidas em coelhos (Oryctolagus cuniculus Linnaeus, 1758), a partir dos quais mais de 50% das larvas e ninfas foram recuperados, embora apenas uma pequena porção tenha realizado ecdise. Os adultos não se fixaram nos coelhos, o que sugere que as condições experimentais eram inadequadas para os requisitos dessa espécie. Os dados obtidos indicam que A. nodosum é altamente dependente de seu hospedeiro e ambiente, enquanto em condições de laboratório e pela escolha do hospedeiro para o estudo não foram obtidos resultados satisfatórios, e novos estudos com diferentes hospedeiros e novas condições ambientais devem ser elaborados.Palavras-chave: Carrapato, hospedeiro, biologia, Brasil, Amblyomma nodosum.

Dogs, cats, parasites, and humans in Brazil: opening the black box

2014

Dogs and cats in Brazil serve as primary hosts for a considerable number of parasites, which may affect their health and wellbeing. These may include endoparasites (e.g., protozoa, cestodes, trematodes, and nematodes) and ectoparasites (i.e., fleas, lice, mites, and ticks). While some dog and cat parasites are highly host-specific (e.g., Aelurostrongylus abstrusus and Felicola subrostratus for cats, and Angiostrongylus vasorum and Trichodectes canis for dogs), others may easily switch to other hosts, including humans. In fact, several dog and cat parasites (e.g., Toxoplasma gondii, Dipylidium caninum, Ancylostoma caninum, Strongyloides stercoralis, and Toxocara canis) are important not only from a veterinary perspective but also from a medical standpoint. In addition, some of them (e.g., Lynxacarus radovskyi on cats and Rangelia vitalii in dogs) are little known to most veterinary practitioners working in Brazil. This article is a compendium on dog and cat parasites in Brazil and a call for a One Health approach towards a better management of some of these parasites, which may potentially affect humans. Practical aspects related to the diagnosis, treatment, and control of parasitic diseases of dogs and cats in Brazil are discussed.
