Tiña incógnita y granuloma de Majocchi adquirido de un erizo. Un caso mexicano / Mexican case of tinea incognito and granuloma de Majocchi acquired from a hedgehog

Resumen Las mascotas exóticas, como el erizo de tierra, son capaces de transmitir al ser humano diferentes infecciones, como salmonelosis, micobacterias, protozoos como Cryptosporidium parvum, y dermatofitosis. Presentamos el caso de un paciente adulto masculino, que recientemente había adquirido un erizo de tierra, que presentó en la mano una lesión de tiña incógnita y un granuloma de Majocchi. Se identificó el agente etiológico como Trichophyton erinacei, por cultivo micológico y biología molecular. El paciente se trató con terbinafina por vía oral, por seis meses, con excelente respuesta.

Exotic pets, such as the ground hedgehog, are capable of transmitting to the human being different zoonoses, such as salmonellosis, mycobacteria, protozoa such as Cryptosporidium parvum, and dermatophytosis. We present the case report of a male adult patient, who had recently acquired a ground hedgehog, who presented in his hand a ringworm lesion incognito and a Majocchi granuloma. The etiological agent was identified as Trichophyton erinacei by mycological culture and molecular biology. The patient was treated with terbinafine oral, with excellent response.

Prevalence of coxiella burnetii in human, animal hosts and hard ticks in west Mazandaran province; Iran, 2003-4

Query [Q] fever is caused by hard ticks infected by Coxiella burnetii. It belongs to a group of diseases, classified as zoonosis, that are common between human-beings and animals. This study was conducted with the objective of defining the prevalence of Coxiella burnetii in humans, animal hosts and hard ticks in the western part of the Mazandaran province. Blood samples were collected from subjects randomly selected from individuals working in professions that brought them in close contact with animals. We also obtained blood samples from randomly selected farm animals, and a limited number of samples from stray dogs in the community. Hard ticks were collected from the bodies of farm animals and also from the shrubs around the farms. The ticks were identified by genus, species and developmental stage. All blood samples were tested by PCR. With the aid of two pairs of primers especially designed 16S rRNA for Coxiella burnetii, PCR and then Nested-PCR was done on each sample. A total of 2417 hard ticks were removed from: animal bodies [1644] and from the shrubbery [773]. The hard tick species were identified as follow: - Ixodes ricinus [72%] - Hyalomma anatolicum anatolicum [15%] - Boophilus annulatus [9%] - Haemaphysalis sulcata [3%] - Dermacentor marginatus [1%] No positive case of Coxiella burnetii was observed in 1052 investigated samples in this study [120 humans, 135 sheeps, 102 cows, 60 goats, 20 dogs, 10 hedgehogs and 605 hard ticks]. This study did not find any evidence of contamination with Coxiella burnetii in the samples collected from the rural areas of Western Mazandaran. To define the prevalence of this microorganism in different parts of northern Iran further epidemiological studies are necessary
