treatment with a Neem Seed Extract mitestop of beetle larvae parasitizing the plumage of poultry
Parasitology Research, 2012Co-Authors: Volker Walldorf, Fathy Abdelghaffar, Heinz Mehlhorn, Saleh Alquraishy, Khaled A S Alrasheid, Julia MehlhornAbstract: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.

Effects of a Neem Seed Extract (MiteStop®) on mallophages (featherlings) of chicken: in vivo and in vitro studies
Parasitology Research, 2012Co-Authors: Saleh Al-quraishy, Julia Mehlhorn, Fathy Abdel-ghaffar, Khaled A. S. Al-rasheid, Heinz MehlhornAbstract:Mallophages of birds (featherlings) are mostly very tiny and can even as adults better be recognized by their movements than by their elongate body shape when using just the naked eye. Since some species (e.g., the “shaft louse” Menopon gallinae , the elongate feather louse Lipeurus caponis , or Columbicola sp.) may pierce the pulp of feathers or the skin by their biting or scratching mandibles and thus lick the excreted blood, they may be extremely dangerous especially to young birds, even if they only feed by nibbling along the feather surface and/or eat epidermal debris. The present paper reports on the successful treatment of different races of fowls being severely infested with both above cited species. This in vivo treatment was done either by a short dipping of the whole fowl into the 1:33 dilution (with tap water) of a Neem Seed Extract (MiteStop®) or by spraying them with the freshly diluted product. It was seen that the dead mallophages dropped down from the feathers as soon as they were dry again. As a precaution, a second treatment was done by some owners 1 week after the first one in order to eliminate all stages, which eventually might have hatched from untouched nits during the time interval between the two treatments. When controlling the treated fowls 4 weeks after the treatment, in no case (treated once or twice), living motile stages were diagnosed indicating the high efficacy of this nontoxic Neem Seed Extract. When treating in vitro cutoff feathers contaminated with L. caponis , it was seen under the stereomicroscope, that the mallophages tried to run away from the 1:33 water-diluted active compound indicating that there is also a repellent effect. Treated L. caponis stopped leg movements within 3 min and died on their feathers within 1–20 min. Then, the last slight trembling movements of their legs and convulsions of their intestine stopped finally.

Biting and bloodsucking lice of dogs-treatment by means of a Neem Seed Extract (MiteStop®, Wash Away Dog)
Parasitology Research, 2012Co-Authors: Heinz Mehlhorn, Volker Walldorf, Fathy Abdel-ghaffar, Khaled A. S. Al-rasheid, Saleh Al-quraishy, Julia MehlhornAbstract:Dogs infested with lice belonging either to the group of Mallophaga (hairlings, i.e., Trichodectes canis) or Anoplura (bloodsucking lice, e.g., Linognathus setosus) were washed with the Neem Seed preparations MiteStop® or Wash Away Dog. It was found that a single treatment with one of these products killed both motile stages and those developing inside eggs (nits) being glued at the hair. In both cases the product had been left for 20 min onto the hair before it was washed away just with normal tap water.

efficacy of a single treatment of head lice with a Neem Seed Extract an in vivo and in vitro study on nits and motile stages
Parasitology Research, 2012Co-Authors: Fathy Abdelghaffar, Saleh Alquraishy, Khaled A S Alrasheid, Heinz MehlhornAbstract:An anti-louse shampoo (Licener®) based on a Neem Seed Extract was tested in vivo and in vitro on its efficacy to eliminate head louse infestation by a single treatment. The hair of 12 children being selected from a larger group due to their intense infestation with head lice were incubated for 10 min with the Neem Seed Extract-containing shampoo. It was found that after this short exposition period, none of the lice had survived, when being observed for 22 h. In all cases, more than 50–70 dead lice had been combed down from each head after the shampoo had been washed out with normal tap water. A second group of eight children had been treated for 20 min with identical results. Intense combing of the volunteers 7 days after the treatment did not result in the finding of any motile louse neither in the 10-min treated group nor in the group the hair of which had been treated for 20 min. Other living head lice were in vitro incubated within the undiluted product (being placed inside little baskets the floor of which consisted of a fine net of gauze). It was seen that a total submersion for only 3 min prior to washing 3× for 2 min with tap water was sufficient to kill all motile stages (larvae and adults). The incubation of nits at 30°C into the undiluted product for 3, 10, and 20 min did not show differences. In all cases, there was no eyespot development or hatching larvae within 7–10 days of observation. This and the fact that the hair of treated children (even in the short-time treated group of only 10 min) did not reveal freshly hatched larval stages of lice indicate that there is an ovicidal activity of the product, too.

Observations on effects of a Neem Seed Extract (MiteStop®) on biting lice (mallophages) and bloodsucking insects parasitizing horses
Parasitology Research, 2012Co-Authors: Saleh Al-quraishy, Julia Mehlhorn, Fathy Abdel-ghaffar, Khaled A. S. Al-rasheid, Heinz MehlhornAbstract:The hair of 300 horses belonging to short hair and long hair races had been routinely treated during the last 3 years with a Neem Seed Extract (MiteStop®) in order to kill mallophages (e.g., specimens of the genus Werneckiella ). It was found that in all cases, a hidden infestation with these biting lice had existed, which became visible when the product (diluted 1:20 with tap water) was brushed onto the hair. The mallophages left the body surface and became visible as a fine “wooly looking” layer at the tips of the hair. Furthermore, this treatment stopped the forming of dandruff of the skin of the horses, which, in case of heavy mallophage infestations, had looked like being powdered. Another interesting result of the treatment was reported by the riders. They described that the product had a considerable repellent effect on bloodsucking tabanids, mosquitoes, ceratopogonids, simuliids, as well as on licking flies. This repellency effect was noted to last for up to 7 days if the horses were not washed.

Ovicidal effects of a Neem Seed Extract preparation on eggs of body and head lice
Parasitology Research, 2011Co-Authors: Heinz Mehlhorn, Fathy Abdel-ghaffar, Khaled A. S. Al-rasheid, Jürgen Schmidt, Margit SemmlerAbstract:The eggs (nits) of head and body lice ( Pediculus humanus capitis , Pediculus humanus corporis ) were incubated for 5, 10, 15, 20, 30 or 45 min into a Neem Seed Extract contained in a fine shampoo formulation (e.g. Wash Away® Louse), which is known for its significant killing effects of larvae and adults of head lice. The aim of the study was to test whether the developmental stages inside the eggs are also killed after the incubation into the shampoo. It was found that an incubation time of only 5 min was sufficient to prohibit any hatching of larvae, whilst 93 ± 4% of the larvae in the untreated controls of body lice hatched respectively about 76% of the controls in the case of head lice. Apparently, the Neem-based shampoo blocked the aeropyles of the eggs, thus preventing the embryos of both races of lice from accessing oxygen and from releasing carbon dioxide. Thus, this product offers a complete cure from head lice upon a single treatment, if the lice (motile stages, eggs) are fully covered for about 10 min.

in vitro efficacy of byemite and mite stop on developmental stages of the red chicken mite dermanyssus gallinae
Parasitology Research, 2009Co-Authors: Fathy Abdelghaffar, Margit Semmler, Khaled A S Alrasheid, Heinz MehlhornAbstract:The present in vitro study shows the efficacy of two antimite products (ByeMite® = phoxim, Mite-Stop® = Neem Seed Extract) against all developing stages of the important red chicken mite Dermanyssus gallinae (obtained at two farms in France and Germany). While permanent contact with the active compound led to an efficacy of 100% in the case of Mite-Stop® on mites in both farms, there was only a 96.2% killing effect of ByeMite® on the mites of the French farm. Even short contacts of only 4 s killed 100% of mites in the case of Mite-Stop® at the French farm and only 84.5% in the German farm. ByeMite®, on the other hand, killed only 27.8% (Germany) and 30% (France) when mites got the chance to escape from the treated grounds to untreated ones. When using only the half doses of both products, Mite-Stop® still reached, after permanent contact, 100% activity on the German farm and 98.2% in France, while ByeMite® killed 93.8% (Germany) and 90.6% (France). Short contact to half doses of course reduced the activity of both products (Mite-Stop® = 59.3% in France, 22.1% in Germany; ByeMite® = 28.8% in France, 18.8% in Germany). With respect to the fumigant activity of the products, the strains of D. gallinae reacted differently. While Mite-Stop® showed a clear fumigant activity in the case of the German mites, this product did not affect the French mites by air distribution, neither did ByeMite® in both cases. Therefore, mites have to come in contact with both products. Against Mite-Stop®, there was apparently no resistance and low doses have high efficacy after even short contacts, which regularly occur in a treated stable, where mites have the chance to leave treated places to untreated hidden spots.

Neem Seed Extract shampoo, Wash Away Louse®, an effective plant agent against Sarcoptes scabiei mites infesting dogs in Egypt
Parasitology Research, 2008Co-Authors: Fathy Abdel-ghaffar, Saleh Al-quraishy, Hassan Sobhy, Margit SemmlerAbstract:In the present study, the efficacy of water-free Neem Seed Extract shampoo Wash Away Louse®, provided by Alpha-Biocare GmbH, Düsseldorf (Germany), was investigated against Sarcoptes scabiei infesting dogs in Egypt. Ten naturally infested dogs were collected from different areas in the Nile delta. The occurrence of lesions, hair loss, and skin inflammation were regarded as signs of infestation and proved by detection of adult parasites and their developmental stages in scrapings of infested lesions. Adequate amount of the provided shampoo was applied topically and spread on the infested areas daily for 14 successive days. Scraping examinations were used to follow up the healing process. At day 7 of application, four dogs were completely free of mites as was proven by the disappearance of adults and/or any developmental stages of mites. The remaining six dogs showed a clear decrease in mite counts. By the end of the treatment (after 14 days), only a small number of mites were found in two dogs, while eight dogs were completely cured as was proven by mite counts and disappearance of clinical signs. No remarkable signs of side effects or adverse reactions were observed throughout the study.

Field study on the efficacy of an Extract of Neem Seed (Mite -Stop®) against the red mite Dermanyssus gallinae naturally infecting poultry in Egypt
Parasitology Research, 2008Co-Authors: Fathy Abdel-ghaffar, Saleh Al-quraishy, Hassan M. Sobhy, Margit SemmlerAbstract:Infestations with the poultry red mite Dermanyssus gallinae represent a major ectoparasite problem in poultry and affects egg and meat production worldwide. The effects of the Neem Seed product Mite-Stop® against the red poultry mite were investigated. Five primitive poultry farms in two small villages in the Nile Delta and Giza district were selected for the study. The Neem Extract was diluted 1:40 and 1:50 with tap water just prior to use. Application of the two dilutions of the provided product was performed to soil, cracks and crevices of the examined area as well as to mite-infested birds on day 0 and day 7. Two hours after treatment soil dust was collected from sprayed regions of the stable and from unsprayed control regions of the same stable. The treated chickens were also checked for mites 2 h after each treatment. The examination of the chickens 2 h after spraying showed that they were free of mites. The examination of treated soil with the Tullgren funnel apparatus 2 h after the first spraying on day 0 already showed a considerable reduction of living mites compared to controls. Seven days after the first treatment of the soil the number of living mites was reduced for 80% in the treated soil and decreased even more after the second spraying, since those larvae that had hatched from eggs in the meantime were killed. The 1:40 dilution of the Neem Seed Extract with tap water was superior to the 1:50 dilution. These results clearly show a very high killing rate of the Extract, if the mites come in direct contact with the compound. However, in order to obtain extinction also of hidden and freshly hatched stages repeated spraying should be done three times within 8–10 days.

efficacy of Neem Seed Extract shampoo on head lice of naturally infected humans in egypt
Parasitology Research, 2007Co-Authors: Fathy Abdelghaffar, Margit SemmlerAbstract:Sixty heavily lice-infested male and female children (4–15 years) were selected and subjected to the treatment with a Neem Seed Extract shampoo. Twenty to thirty milliliter of the shampoo were thoroughly mixed with completely wet hair and rubbed in to reach the skin of the scalp. After 5, 10, 15 and 30 min, the shampoo was washed out and the hair basically combed. Head lice were collected and examined. The Neem Seed Extract shampoo proved to be highly effective against all stages of head lice. No obvious differences regarding the efficacy of the shampoo were observed between an exposure time of 10, 15 or 30 min. No side effects, such as skin irritation, burning sensations, or red spots on the scalp, forehead or neck, respectively, were observed.

The efficacy of Neem Seed Extracts (Tre-san®, MiteStop®) on a broad spectrum of pests and parasites
Parasitology Research, 2010Co-Authors: Günter Schmahl, Fathy Abdel-ghaffar, Khaled A. S. Al-rasheid, Sven Klimpel, Heinz MehlhornAbstract:The paper summarizes the acaricidal and insecticidal effects of a patented Neem Seed Extract when diluted 1:10 with shampoo or 1:20, 1:30, 1:33, 1:40, respectively, 1:66 with tap water. It was shown that a broad range of pests and parasites, such as house dust mites, poultry mites, harvest mites, Ixodes and Rhipicephalus ticks, cat fleas (adults, larvae), bed bugs (all stages), head lice and mallophaga, cockroaches (genera Blatta , Blattella , Gomphadorhina ), raptor bugs ( Triatoma ), and even food-attacking beetle ( Tenebrio molitor ) might be controlled with this Extract, which is available as Tre-san® (against house dust mites) and MiteStop® (against mites, ticks, insects of any kind) to become water diluted or as Wash Away Louse® or Picksan LouseStop® being diluted in a shampoo. Tests on skin compatibility proved that there are no skin irritations during or after use. However, some target species are less sensible (beetles, Triatoma stages, fly maggots), while the specimens of the other species cited above were successfully killed even at low concentrations of the Extract.

treatment with a Neem Seed Extract mitestop of beetle larvae parasitizing the plumage of poultry
Parasitology Research, 2012Co-Authors: Volker Walldorf, Fathy Abdelghaffar, Heinz Mehlhorn, Saleh Alquraishy, Khaled A S Alrasheid, Julia MehlhornAbstract: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.

efficacy of a single treatment of head lice with a Neem Seed Extract an in vivo and in vitro study on nits and motile stages
Parasitology Research, 2012Co-Authors: Fathy Abdelghaffar, Saleh Alquraishy, Khaled A S Alrasheid, Heinz MehlhornAbstract:An anti-louse shampoo (Licener®) based on a Neem Seed Extract was tested in vivo and in vitro on its efficacy to eliminate head louse infestation by a single treatment. The hair of 12 children being selected from a larger group due to their intense infestation with head lice were incubated for 10 min with the Neem Seed Extract-containing shampoo. It was found that after this short exposition period, none of the lice had survived, when being observed for 22 h. In all cases, more than 50–70 dead lice had been combed down from each head after the shampoo had been washed out with normal tap water. A second group of eight children had been treated for 20 min with identical results. Intense combing of the volunteers 7 days after the treatment did not result in the finding of any motile louse neither in the 10-min treated group nor in the group the hair of which had been treated for 20 min. Other living head lice were in vitro incubated within the undiluted product (being placed inside little baskets the floor of which consisted of a fine net of gauze). It was seen that a total submersion for only 3 min prior to washing 3× for 2 min with tap water was sufficient to kill all motile stages (larvae and adults). The incubation of nits at 30°C into the undiluted product for 3, 10, and 20 min did not show differences. In all cases, there was no eyespot development or hatching larvae within 7–10 days of observation. This and the fact that the hair of treated children (even in the short-time treated group of only 10 min) did not reveal freshly hatched larval stages of lice indicate that there is an ovicidal activity of the product, too.

in vitro efficacy of byemite and mite stop on developmental stages of the red chicken mite dermanyssus gallinae
Parasitology Research, 2009Co-Authors: Fathy Abdelghaffar, Margit Semmler, Khaled A S Alrasheid, Heinz MehlhornAbstract:The present in vitro study shows the efficacy of two antimite products (ByeMite® = phoxim, Mite-Stop® = Neem Seed Extract) against all developing stages of the important red chicken mite Dermanyssus gallinae (obtained at two farms in France and Germany). While permanent contact with the active compound led to an efficacy of 100% in the case of Mite-Stop® on mites in both farms, there was only a 96.2% killing effect of ByeMite® on the mites of the French farm. Even short contacts of only 4 s killed 100% of mites in the case of Mite-Stop® at the French farm and only 84.5% in the German farm. ByeMite®, on the other hand, killed only 27.8% (Germany) and 30% (France) when mites got the chance to escape from the treated grounds to untreated ones. When using only the half doses of both products, Mite-Stop® still reached, after permanent contact, 100% activity on the German farm and 98.2% in France, while ByeMite® killed 93.8% (Germany) and 90.6% (France). Short contact to half doses of course reduced the activity of both products (Mite-Stop® = 59.3% in France, 22.1% in Germany; ByeMite® = 28.8% in France, 18.8% in Germany). With respect to the fumigant activity of the products, the strains of D. gallinae reacted differently. While Mite-Stop® showed a clear fumigant activity in the case of the German mites, this product did not affect the French mites by air distribution, neither did ByeMite® in both cases. Therefore, mites have to come in contact with both products. Against Mite-Stop®, there was apparently no resistance and low doses have high efficacy after even short contacts, which regularly occur in a treated stable, where mites have the chance to leave treated places to untreated hidden spots.

efficacy of Neem Seed Extract shampoo on head lice of naturally infected humans in egypt
Parasitology Research, 2007Co-Authors: Fathy Abdelghaffar, Margit SemmlerAbstract:Sixty heavily lice-infested male and female children (4–15 years) were selected and subjected to the treatment with a Neem Seed Extract shampoo. Twenty to thirty milliliter of the shampoo were thoroughly mixed with completely wet hair and rubbed in to reach the skin of the scalp. After 5, 10, 15 and 30 min, the shampoo was washed out and the hair basically combed. Head lice were collected and examined. The Neem Seed Extract shampoo proved to be highly effective against all stages of head lice. No obvious differences regarding the efficacy of the shampoo were observed between an exposure time of 10, 15 or 30 min. No side effects, such as skin irritation, burning sensations, or red spots on the scalp, forehead or neck, respectively, were observed.
