“…Scant reports on pentastomes and cancer have been published in both veterinary and human medicine. Pentastomiasis was diagnosed in a 20-year-old female oriental small-clawed otter ( Aonyx cinereus ) with thyroid gland carcinoma [ 275 ], in a boy with acute leukaemia [ 276 ], and in a man with metastatic thyroid cancer [ 277 ]. Except for the dog described by Bordicchia et colleagues the most probable scenario in these instances appears to be secondary infection resulting from neoplastic debilitation.…”

Parasite infection is one of the many environmental factors that can significantly contribute to carcinogenesis and is already known to be associated with a variety of malignancies in both human and veterinary medicine. However, the actual number of cancerogenic parasites and their relationship to tumor development is far from being fully understood, especially in veterinary medicine. Thus, the aim of this review is to investigate parasite-related cancers in domestic and wild animals and their burden in veterinary oncology. Spontaneous neoplasia with ascertained or putative parasite etiology in domestic and wild animals will be reviewed, and the multifarious mechanisms of protozoan and metazoan cancer induction will be discussed.

Popularity of pet otters on YouTube: evidence of an emerging trade threat

In response to growing reports of otters in the pet trade, and suggestions that the popularity of pet otters on social media may be driving demand, we collated YouTube videos of pet otters to test for trends in the number of videos published, their exposure (number of views) and popularity. We used English-language search terms to provide a global overview, as well as local language search terms for four South East Asian countries identified as being of potential importance in the pet otter trade (Indonesia, Malaysia, Thailand and Vietnam), and Japan. We found that not only had the number of videos depicting pet otters increased in the last two to three years (2016–2018), but that their popularity and/or engagement had also increased. Notwithstanding some country-level differences in the details of effects observed, the greatest increases in both the number of videos produced and their popularity occurred in Indonesia and Japan. At a global-level, commercial “viral” video sites appeared to be influential in terms of posting highly popular pet otter videos. At a national level, potentially influential videos tended to be produced by four or five individual otter owners. The appearance of phrases such as “I want one” in the comments section of the English-language videos, although not necessarily a statement of actual intent, suggests that these videos may be driving demand amongst their viewers and followers; similar analyses of video comments in each local language are warranted. Our results show an increase in social media activity that may not only be driving the apparent increase in popularity, but also amplifying awareness of the availability of these animals as pets, as well as creating and perpetuating the (erroneous) perception of otters as a suitable companion animal. At a global level, there are welfare concerns associated with otters in the pet trade, and, in South East Asia specifically, there are serious conservation concerns. We recommend increased regulation of these activities on social media, increased public awareness of the negative impacts of the pet trade on otters, and increased international protection. Specifically, we suggest the need to uplist both small-clawed and smooth-coated otters (Aonyxcinereus and Lutrogaleperspicillata, respectively) to CITES Appendix 1.

“…12 Boneinvading lymphoma leading to paraplegia 12 and functional thyroid carcinoma with metastasis to lymph nodes (LNs) have been described in Asian small-clawed otters. 3 Lymphoma is a relatively common tumor in the order Carnivora, both in domestic and wild species, but are reported uncommonly in family Mustelidae-except in domestic ferrets (Mustela putorius furo). 11 Lymphoma has been reported only rarely in the subfamily Lutrinae (Table 1).…”

Intestinal T-cell lymphoma in an Asian small-clawed otter: case report and literature review of lymphoma in the subfamily Lutrinae

et al. 2022

The Asian small-clawed otter ( Aonyx cinereus) is an endangered species that is common in zoologic collections. A 17-y-old female Asian small-clawed otter under human care, with a clinical history of chronic renal disease, was euthanized because of deteriorating health. Histologically, the jejunal wall was infiltrated by a monomorphic population of small neoplastic lymphocytes that expanded the lamina propria of the villi and crypts, and on rare occasions invaded the submucosa. The tumor was composed of T cells (CD3+) with a proliferation index of 16%. Based on the World Health Organization (WHO) Classification of Hematopoietic Neoplasms in Domestic Animals, this lymphoma was classified as an enteropathy-associated T-cell lymphoma (EATL) type 2. We also present here a review of the literature on intestinal lymphoma in the subfamily Lutrinae (otters).
