“…A single case report of dog tungiasis from Denmark suggested that ivermectin is an effective drug [ 49 ]. However, the dog was treated subcutaneously with ivermectin, which is not licensed for treatment of dogs due to severe adverse effects in mdr-1 deficient animals.…”

BackgroundIn endemic communities, zoonotic tungiasis, a severe skin disease caused by penetrating female sand fleas, is a public health hazard causing significant human and animal morbidity. No validated drugs are currently available for treatment of animal tungiasis. Due to the reservoir in domestic animals, integrated management of human and animal tungiasis is required to avert its negative effects.Methods and principal findingsA topical aerosol containing chlorfenvinphos 4.8%, dichlorphos 0.75% and gentian violet 0.145% licensed to treat tick infestations, myiasis and wound sepsis in animals in the study area, was tested for its potential tungicidal effects in a randomized controlled field trial against pig tungiasis in rural Uganda. Animals with at least one embedded flea were randomized in a treatment (n = 29) and a control (n = 26) group. One week after treatment, 58.6% of the treated pigs did not show any viable flea lesion whereas all control pigs had at least one viable lesion. After treatment the number of viable lesions (treated median = 0, overall range = 0–18 vs. control median = 11.5, range = 1–180) and the severity score for estimating acute pathology in pig tungiasis (treated median = 1, range = 0–3.5 vs. control median = 7, range = 0–25) were significantly lower in treated than in control pigs (p < 0.001). In the treatment group the median number of viable flea lesions decreased from 8.5 to 0 (p < 0.001). Similarly, the median acute severity score dropped from 6 to 1 (p < 0.001). Every pig in the treatment group showed a decrease in the number of viable fleas and tungiasis-associated acute morbidity while medians for both increased in the control group.ConclusionsThe study demonstrates that a topical treatment based on chlorfenvinphos, dichlorphos and gentian violet is highly effective against pig tungiasis. Due to its simplicity, the new approach can be used for the treatment of individual animals as well as in mass campaigns.

“…Tungiasis also occurs in a wide range of domestic, peri-domestic and wild animals [ 12 – 14 ] usually alongside human tungiasis in endemic communities of South America and sub-Saharan Africa [ 12 – 15 ]. With the increasing number of international journeys with pets, animal tungiasis is also being detected in non-endemic countries [ 16 ]. In animals, sand fleas mainly localize on legs but also infect other organs which often come into contact with the ground, for example; mammary glands, gonads, muzzle and the tail [ 12 , 17 – 20 ].…”

Tungiasis-associated morbidity in pigs and dogs in endemic villages of Uganda

et al. 2016

BackgroundTunga penetrans (Insecta, Siphonaptera, Tungidae) causes severe morbidity among heavily infected humans and animals in Latin America and sub-Saharan Africa. The clinical pathology of tungiasis in animals has never been studied systematically.MethodsThis was a cross-sectional study conducted between January to March 2015, aimed at describing tungiasis-associated clinical pathology in 121 and 20 T. penetrans-infected pigs and dogs, living in nine and five endemic rural villages respectively located in Bugiri District, Busoga, Uganda.ResultsThe parasite load of infected animals ranged from one to 246 (median 8) and one to eight (median 2) in pigs and dogs, respectively. In pigs 99.3 % and in dogs 100 % of the lesions were located on feet. In pigs, hind legs were significantly more affected than front legs (90.9 % vs. 57.9 %; p = 0.002) and also had more lesions than the front legs (median 5 vs. 1; p = 0.0001). However, in dogs localization of lesions between front and hind legs never differed significantly (front, 50 % vs. hind, 65 %; p = 0.51) and so were the number of lesions (median front = 0.5 vs. median hind = 2; p = 0.7). Acute and chronic clinical pathology coexisted. The most common disease manifestations in pigs were hoof wall erosions (68.6 %), tissue necrosis of hoof wall and skin (66.1), pain at infection sites (47.9 %), hoof deformity (45.5 %), fissures (44.6 %) and edema (44.6 %). In dogs, tungiasis mainly presented with pain at attachment site (80 %), ulcers (55 %), necrosis (30 %) as well as hyperemia and edema (both 15 %). One pig had lost dew claws while two had loose detaching claws. Despite a lower number of sand fleas, a higher proportion of infected dogs (20 %) than pigs (5.8 %) exhibited functional limb use difficulties (p = 0.05).ConclusionsThe pattern of clinical manifestations in pigs and dogs were very similar to those reported from affected humans and rats. The important morbidity associated with animal tungiasis makes the disease a serious veterinary health problem in sub-Saharan Africa warranting treatment and control for optimal animal production.

“…Apesar de a literatura estimar que a tunguíase seja de elevada frequência e de distribuição mundial, sendo diagnosticada em várias espécies (Heukelbach et al, 2004Loft Nissen, 2009, no presente trabalho a frequência da tunguíase foi baixa, acometendo apenas um cão, macho, da raça Pitbull, com três meses de idade. Entretanto, Souza et al (2009b), no Rio Grande do Sul, observaram dois casos, sem indicação de sexo, raça e idade.…”

RESUMO Diante da carência de estudos sobre a frequência de dermatopatias que acometem cães por região geográfica no Brasil, o presente estudo objetivou conhecer a frequência das principais doenças cutâneas que afetam cães na região metropolitana de João Pessoa, Paraíba, Brasil. Os dados foram coletados de cães que passaram por atendimento dermatológico no período de setembro de 2014 a dezembro de 2016. Além dos exames clínicos e dermatológicos os cães foram submetidos a exames complementares (citológico, raspado de pele, parasitológico, tricograma, bacteriológico, micológico, histopatológico e molecular). No período do estudo, foram atendidos 1.083 cães, em que 18,65% (202/1.083) apresentavam algum tipo de dermatopatia não tumoral. Dos 202 cães acometidos, 51,49% (104/202) eram machos e 48,51% (98/202), fêmeas. Desses 202 cães, 13 tinham dois diagnósticos, totalizando 215 dermatopatias. Dos cães afetados, 62,87% (127/202) eram de raça definida e 37,13% (75/202), sem raça definida (SRD). As lesões observadas com mais frequência caracterizaram-se por áreas alopécicas, hipotricoicas, maculosas, erosivas e ulcerativas, placoides, eritematosas, assim como comedões, colaretes, seborreia. As dermatopatias parasitárias foram as mais frequentes (35,35%; 76/215), seguidas pelas dermatopatias bacterianas (24,19%; 52/215), dermatopatias alérgicas (20,00%; 43/215), dermatopatias fúngicas (17,21%; 37/215), dermatopatias por outras causas (2,32%; 5/215) e pelas dermatopatias autoimunes (0,93%; 2/215). Os exames físicos e dermatológicos, incluindo anamnese detalhada, histórico clínico apurado, associado a exames complementares, são ferramentas importantes para o diagnóstico das dermatopatias em cães. Presume-se que a frequência de dermatopatias em cães na região de estudo possa ser maior do que a observada.
