“…However, those reports did not recover adult worms in experimentally infected animals and might have misidentified the obtained L3 larvae from the closely related species A. cantonensis or A. minascensis , since 11 out of 18 known A. costaricensis -intermediate hosts have been reported also as competent hosts for A. cantonensis. Moreover, Biomphalaria glabrata [ 64 ], Biomphalaria straminea [ 65 ], Biomphalaria tenagophila [ 65 ] and Sarasinula linguaeformis [ 66 ] have been found naturally infected with A. costaricensis and A. cantonensis.…”

Abdominal angiostrongyliasis in the Americas: fifty years since the discovery of a new metastrongylid species, Angiostrongylus costaricensis

et al. 2021

Angiostrongylus costaricensis is a zoonotic parasitic nematode described for the first time in 1971 by Pedro Morera and Rodolfo Céspedes in Costa Rica. This parasite causes an infection known as abdominal angiostrongyliasis, affecting mainly school-aged children and young adults. Infection with A. costaricensis has been associated with a myriad of rodent and mollusk species in the Americas and the Caribbean, as its natural hosts and reservoirs. In this commemorative review, we highlight the extensive research collected through a 50-year journey, which includes ecological, pathological, and molecular studies on A. costaricensis and its implicated disease. We also identify major knowledge gaps in its evolutionary history, the ecological role of imported and invasive mollusk species, and immune response. We propose that the advent of -omics analyses will allow us to gather novel information regarding A. costaricensis biology and infection dynamics, as well as to promote the design of much-needed sensitive and specific diagnostic tools.

“…The volume of the albumen gland is smaller in snails with a greater number of parasitic cysts, which could be a sign of less galactogen storage. A decrease in galactogen of albumen glands (about 50%) and in the average number of eggs per egg mass was reported for B. glabrata (Tunholi-Alves et al, 2011) and Biomphalaria straminea (Lima et al, 2017) experimentally infected with A. cantonensis . As the ovotestis of these infected snails maintained a normal functional appearance until 21 days of infection, the authors proposed that the effect of parasitism appears to be on oviposition and not on gametogenesis of B. glabrata and B. straminea .…”

“…As the ovotestis of these infected snails maintained a normal functional appearance until 21 days of infection, the authors proposed that the effect of parasitism appears to be on oviposition and not on gametogenesis of B. glabrata and B. straminea . The decrease of the galactogen synthesis, caused directly or indirectly by the development of A. cantonensis larvae, would reduce the storage of this polysaccharide in the albumen gland and its transfer to the eggs, compromising oviposition (Tunholi-Alves et al, 2011; Lima et al, 2017). No cysts were found in the ovotestis of M. abbreviatus .…”

“…The presence of nematode larvae can cause a series of changes in both intermediate and definitive hosts, such as impairment of immune responses (Lange et al, 2017), tissue damage and arrested reproductive development (Hurd, 2001; Tunholi-Alves et al, 2011; Lima et al, 2017; Lima et al, 2020; Amaral et al, 2022), behavioral changes (Yanoviak et al, 2008; Boze and Moore, 2014), and the evolution of host immune defense traits (Moné et al, 2011; Seppälä et al, 2021). Experimental infections of snails as intermediate host with Angiostrongylus cantonensis and Heterorhabditis indica also resulted in alterations of intermediary and oxidative metabolism of Biomphalaria glabrata (Tunholi-Alves et al, 2011, 2012, 2014), changes in nitrogenous end-product excretion of Bradybaena similaris (Tunholi et al, 2014), and changes in total protein, urea, and uric acid concentrations in Achatina fulica (Tunholi-Alves et al, 2015).…”

The nematode Cruzia tentaculata is reported here for the first time in the land snail Megalobulimus abbreviatus in southern Brazil. The snails were infected with a high prevalence of larvae up to the L3 stage (68.6%). Cysts were located mainly in the mantle (pulmonary cavity) and the nerve ring. No other helminths were identified in the collected snails. Some physiological aspects were compared between snails infected with L3 larvae and non-infected snails and among infected animals with different parasite loads. No differences were found in hemolymph protein, glucose, or urea content between L3-infected and non-infected snails, nor among animals with different parasite loads. Discontinuous lesions in the rectum associated with the presence of encapsulated larvae were visible in animals with high parasite loads and were more frequent in adult animals. All analyses were carried out during the breeding season; however, the albumen glands of mature snails had a smaller volume in those with higher parasite loads. Ovotestis weight was also significantly negatively correlated with parasite load. Snail reproductive capacity could, therefore, be partially impaired but only for individuals with higher parasite loads. Considering only the measured parameters, natural infection by C. tentaculata does not appear to affect intermediary metabolism of M. abbreviatus. A greater number of larvae and greater severity of tissue injuries are more frequently observed in older snails.

Zoonotic parasites carried by invasive alien species in China

et al. 2019

BackgroundThe invasive alien species may lead to great environmental and economic crisis due to its strong capability of occupying the biological niche of native species and altering the ecosystem of the invaded area. However, its potential to serve as the vectors of some specific zoonotic pathogens, especially parasites, has been neglected. Thus, the damage that it may cause has been hugely underestimated in this aspect, which is actually an important public health problem. This paper aims to discuss the current status of zoonotic parasites carried by invasive alien species in China.Main bodyThis review summarizes the reported zoonotic parasites carried by invasive alien species in China based on the Database of Invasive Alien Species in China. We summarize their prevalence, threat to human health, related reported cases, and the roles of invasive alien species in the life cycle of these parasites, and the invasion history of some invasive alien species. Furthermore, we sum up the current state of prevention and control of invasive alien species in China, and discuss about the urgency and several feasible strategies for the prevention and control of these zoonoses under the background of booming international communications and inevitable globalization.ConclusionsInformation of the zoonotic parasites carried by invasive alien species neither in China or worldwide, especially related case reports, is limited due to a long-time neglection and lack of monitoring. The underestimation of their damage requires more attention to the monitoring and control and compulsory measures should be taken to control the invasive alien species carrying zoonotic parasites.Electronic supplementary materialThe online version of this article (10.1186/s40249-018-0512-6) contains supplementary material, which is available to authorized users.
