[Primary amebic meningoencephalitis. Report of a suspicious case and review of the medical literature]. / Meningoencefalitis amebiana primaria. Estudio de un caso sospechoso y revisión de la literatura médica.

The case of a 24-year old patient who, in July 1976, submerged into a canal of Guanimar river and, five days later, had a febrile meningoencephalitic clinical picture, is presented; he was in a very severe condition and recovered without sequelae with a treatment based on amphotericin B. The negative cultures for bacteria, fungi and viruses, the characteristics of cerebrospinal fluid and the observation of free-life amebae in the water of the wash of rhinopharynx and pharingeal cavity allowed to establish, with great accuracy, the presuntive diagnosis of primary amebic meningoencephalitis.

[Otic myiasis in a newborn caused by Calliphoridae larvae of the genus Phaenicia]. / Miiasis ótica en un recién nacido, causada por larvas de "Calliphoridae" del género "Phaenicia".

A 55-day-old newborn with an intense otitis haemorrhagica caused by a Calliphoridae larva of the genus Phaenicia is presented. During an ear lavage the larva was removed. The patient was admitted and once the genus was known he underwent a specific treatment and was discharged completely cured.

[The incidence of Dirofilaria immitis in dogs of Havana City]. / Incidencia de la Dirofilaria immitis en los perros de la ciudad de La Habana.

The significance of the knowledge of the incidence of Dirofilaria immitis in the dog is emphasized since dirofilariasis is a zoonosis which produce subcutaneous tumors which clinical-etiological diagnosis is very difficult. Adult forms are often located in the skin. The percentage of parasitized dogs found in the Havana city is reported. One-hundred-and-two necropsies of gadder dogs depicted that 6,86% of them had Dirofilaria immitis. Results were negative in the remaining 93,13%.

Nuevo método de aislamiento y cultivo de larvas de ancylostoma caninum / New method for ancylostoma caninum larva isolation and culture

Se presenta un nuevo medio y mecanismo de recolección de larvas de helmintos, aprovechando el geotropismo negativo de las larvas y el agua de condensación que impregna las tapas de las placas de Petri, que facilita el desplazamiento de la larva hacia este sitio (hidrotropismo positivo); se obtienen cultivos de larvas, enriquesidos, sin detritus que obstaculicen su utilización para mainipulaciones o trabajos ulteriores (AU)

Estudios sobre nuevas técnicas para el conteo de larvas de nematodes / Studies on new techniques for the nematode larva control

Se expone la técnica de aislamiento de larvas de nematodes (Ancylostoma caninum) con el máximo posible de garantía con relación a su limpieza y utilización para investigación y experimentación. Se señala un método de homogeneización de las larvas y su conteo, con un margen de error, prácticamente despreciable, aplicando los métodos estadísticos recomendados por los doctores Héctor Horrego y Renato Palma en enero de 1972 y distribuidos en este Centro durante el curso de estadística aplicada a la fisiología del aparato digestivo (AU)
