Neobenedenia melleni (Monogenea: Capsalidae) in ornamental reef fish imported to Brazil / Neobenedenia melleni (Monogenea: Capsalidae) em peixes ornamentais de recife importados para o Brasil

Abstract The capsalid monogenean Neobenedenia melleni is known as a lethal pathogen for captured marine teleost ornamental fish, if left untreated. This study reports the occurrence of N. melleni parasitizing four species of ornamental reef fish imported into Brazil and maintained in quarantine: Arabian angelfish (Pomacanthus asfur ), yellowbar angelfish (Pomacanthus maculosus), regal angelfish (Pygoplites diacanthus), and bluecheek butterflyfish (Chaetodon semilarvatus). Ten days after the beginning of quarantine, some fish showed behavioral alterations, such as irritability, and corneal opacity, which were rapidly diagnosed to be caused by monogenean parasites by body surface scraping. The fish from the same batch were treated with two applications of 2 mg L-1 praziquantel each at an interval of four days. Seven days after the first treatment, the mucus surface of the fish was re-examined, which did not reveal the parasites presence being delivered for commercialization.

Resumo Neobenedenia melleni é conhecido como um parasito letal para peixes teleósteos ornamentais marinhos capturados se não tratado. Este estudo relata a ocorrência de N. melleni parasitando quatro espécies de peixes ornamentais importados para o Brazil: Arabian angelfish (Pomacanthus asfur), yellowbar angelfish (Pomacanthus maculosus), regal angelfish (Pygoplites diacanthus) e bluecheek butterflyfish ( Chaetodon semilarvatus). Dez dias depois do início da quarentena, foram observados irritabilidade e opacidade na córnea dos peixes que, foram diagnosticadas com N. melleni na superfície corporal. Todos os peixes foram tratados com duas aplicações de praziquantel 2 mg L-1 em intervalo de quatro dias. Sete dias após o início do tratamento, um novo exame parasitológico foi realizado o qual não revelou a presença dos parasitos, sendo liberados para comercialização.

Infección por Dipylidium caninum en un preescolar: presentación del caso y revisión de la literatura / Dipylidium caninum infection in a 2 year old infant: case report and literature review

Dipylidiasis is a zoonotic parasitic infection caused by the dog tapeworm Dipylidium caninum; it affects both feline and canine species and accidentally, humans. In Chile, as well as in other countries, it is an uncommon infection. A case of a 2 year old child from Casablanca, (a city located in the Valparaíso Región), with an infection by D. caninum, is presented. Clinical manifestations are reviewed, as well as epidemiology in domestic and wild animáis, cases among the published national literature and its treatment and prevention strategies.

La dipilidiasis es una zoonosis parasitaria provocada por Dipylidium caninum, teniasis que afecta a cánidos, félidos y, en forma accidental, al hombre. En Chile, al igual que en otros países, es una infección poco frecuente. Se presenta el caso de un preescolar con una infección por D. caninum, residente en la comuna de Casablanca, Región de Valparaíso. Se revisan las manifestaciones producidas por este agente, la epidemiología en animales domésticos y salvajes, los casos publicados en la literatura nacional, así como su tratamiento y las medidas de prevención.

Infección por dypilidium caninum en un lactante / A case of infection by dypilidium caninum in an infant

Dypilidium caninum es un cestode común en perros y gatos distribuido en todo el mundo. El ser humano, huesped accidental, adquiere la infección a través de las pulgas en asociación con las mascotas infectadas, siendo esta enfermedad más frecuente en niños. Presentamos el caso de una niña de un año y medio de edad, que durante siete meses eliminó proglótidas en las deposiciones, consultando en numerosas oportunidades siendo tratada con fármacos dirigidos a protozoos y nematelmintos. Finalmente, luego de la identificación del Dypilidium caninum se trató a la paciente con niclosamida, evolucionando satisfactoriamente

Cestodosis del equino y las posibilidad de su control / Equine cestodosis and its control possibilities

En consideración a que ha aumentado la prevalencia y los casos clínicos de la cestodosis del equino en Chile, se revisó la literatura de los últimos 15 años. La especie más frecuentemente descrita es Anoplocephala perfoliata. La presente revisión resume, prevalencia e intensidad de infección a nivel mundial, ciclo biológico, patogénesis y las dificultades del diagnóstico y tratamiento. Se analizan las posibilidades del control de la parasitosis en base a una hipótesis epidemiológica

Studies on the comparative efficacy of mebendazole, flubendazole and niclosamide against human tapeworm infections.

The efficacy of Mebendazole and Niclosamide was studied in two groups of 24 and 38 cases, respectively of patients suffering from taeniasis. Mebendazole with dose schedule of 200 and 300 mg twice daily for 3 consecutive days showed a cure rate of 71.42% and 92.30%, whereas Niclosamide at the dose rate of 200mg per patient was 94.76% effective. Flubendazole showed a cure rate of 66.66% only. Mebendazole and Niclosamide possess high taeniacidal activity, ability to reduce the clinical symptoms of taeniasis without any side effects. Niclosamide with high activity and excellent tolerance, is a drug of choice for the treatment of taeniasis in single dose treatment while for hymenolepsiasis it needs extended course.

Case reports of Dipylidium caninum; a pet associated infection.

Two cases of Dipylidium caninum (dog tape worm) infection occurring in children are reported for the first time in Sri Lanka. The diagnosis and treatment with praziquantel, a new broad spectrum antiplatyhelmintic, are described. The importance of this pet associated infection is discussed with special reference to preventive measures.
