“…Occupational asthma has also been described in bean sorters with sensitization to the Mexican bean weevil Zabrotes subfasciatus boh (Wittich, 1940) and in sewage workers, with sensitization to sewage filter flies, Psychoda (Ordman, 1946). Frankland (1953) studied selected workers breeding locusts in two research establishments.…”

Occupational asthma caused by allergy to pigs' urine We report a case of asthma due to occupational exposure to pigs. The cause of the symptoms was exposure to the urine of the animals. This was proved by provoking acute asthma with an inhalation challenge of an extract of pigs' urine at a concentration of 1 g/l. On a second occasion this asthmatic response was blocked by prior treatment with 40 mg sodium cromoglycate (Intal). The patient's serum contained specific IgE antibody to the urine extract which was not found in unexposed controls. Case report The patient, a 21-year-old eczematous woman who enjoyed a vigorous sporting life, playing squash and hockey to a high standard, had not suffered respiratory symptoms since the age of 3. During her second year at university studying agricultural sciences her class visited a pig house. Within two to three minutes she had to leave because she felt as if she was being "stifled with a plastic bag." She took about an hour to recover her breath and within a few minutes her eczema had begun to itch, and this took a further two hours to settle. One year later, within five minutes after starting to watch a laparo-tomy on a pig, she again became short of breath. Her only other exposure to these animals had been during a visit to the pig house in her first year, when she remained symptomless. Skin-prick tests yielded positive reactions to grass, house-dust mite, horse, cat, dog, and pork extract. Pigs' urine (50 ml) was filtered, sterilised, and freeze dried as described1 and reconstituted in Coca's solution at 01 and 1 0 g/l. Skin testing produced a 3 mm weal with the solution at 1 0 g/l. After inhaling a nebulised dose (0-0015 g) for one minute her forced expiratory volume in one second (Vitalograph) fell by 70 % from 2-3 to 0-7 1. The same test was conducted one week later after 40 mg of sodium cromoglycate had been given by inhalation 10 minutes before the challenge. On this occasion her forced expiratory volume in one second fell by nearly 28 %0 from 2-5 to 1-8 1. In each case recordings were made for a further five hours throughout-Chcallenge 3 eDSCG (40 mg).

No non-immediate reaction developed (figure). A radioallergo-sorbent test performed with the same urine extract showed her blood to contain specific IgE antibody, 23-9 % of the counts added in the assay being bound, as compared with 0-73 , with cord blood and a mean of 0-69 %o with six blood-bank controls. Comment Asthma has resulted from inhaling certain proteins in the urine of mice, rats, guinea-pigs, and rabbits in sensitised subjects but not from inhaling the animal serum.' 2 Our patient's sensitivity to pigs' urine raises the possibility that urine of other mammals may also cause...

“…Furthermore, these beetles may become intermediate hosts of parasites when bearing the larvae, cysticercoids of numerous tapeworms (Mehlhorn 2008;Eckert et al 2008). In addition, the feces and the larval exuvial remnants may introduce severe allergic reactions in the breathing system of humans and animals (Wiseman et al 1959;Wittich 1940;Sheldon and Johnston 1941;Klaschka and Jung 1976). Thus control of such part-time parasites and/or food pests is highly desirable, since otherwise the economic win will disappear due to reduction of the egg-laying rate, slow body growth, or due to death as consequence of superinfections of wounds respectively due to transmission of agents of diseases.…”

Treatment with a neem seed extract (MiteStop®) of beetle larvae parasitizing the plumage of poultry

Beetles of the species Alphitobius diaperinus, Dermestes bicolor, and Dermestes lardarius may transmit severe agents of diseases on poultry and may in addition harm as larvae the skin and feathers thus leading to severe economic losses. The present study deals with a control measurement using a neem seed extract (MiteStop®) being diluted with tap water. It was shown that spraying of a 1:33 dilution kills both larvae and adults of these part-time parasites as was previously shown for other parasites such as mites, ticks, and blood sucking or biting insects.
