At this equine farm, two horses over 25 years old presented alopecic lesions in the form of streaks in the masseteric and maxillary region of the face. The clinical and histological features of these animals are described, with dermatological examination revealing the presence of nonoperculated eggs of Gasterophilus sp. when the lesions appeared. The morphology of the eggs corresponded to G. inermis and skin biopsy identified an eosinophilic superficial perivascular dermatitis. The horses were treated once with oral ivermectin, achieving complete resolution of the lesions.

This Microsporidium was monitored during a long-term study to evaluate the infection at apiary and intra-colony levels in six apiaries in four Mediterranean countries (France, Israel, Portugal, and Spain). Parameters on colony strength, honey production, beekeeping management, and climate were also recorded. Except for São Miguel (Azores, Portugal), all apiaries were positive for N. ceranae, with the lowest prevalence in mainland France and the highest intra-colony infection in Israel. A negative correlation between intra-colony infection and colony strength was observed in Spain and mainland Portugal. In these two apiaries, the queen replacement also influenced the infection levels. The highest colony losses occurred in mainland France and Spain, although they did not correlate with the Nosema infection levels, as parasitism was low in France and high in Spain. These results suggest that bo...

The experiment was carried out with 24 colonies and three treatments, which consisted of a solution of different proportions of supplement (0, 3, and 5 mL) diluted in syrup (water and sugar). Although this supplement is effective and indicated for other species of domestic animals, analysis of variance with repeated measures over time did not reveal a significant effect (P > 0.05) of its dose on the weight of the hives, showing that the supply of the vitamin-amino acid supplement does not meet the nutritional requirements of the colony. The use of this product did not have a positive effect on the development of the uruçu bee colonies, so it should not be employed as a major source of amino acids and vitamins in the diet of bees. Beekeepers are suggested to provide uruçu bees with an abundant diversity of plants so that they...

In the present work we have made a comparative study of these bees and Apis mellifera iberica, by means of a morphometric study, putting under the values obtained a descriptive statistical research, evaluating the normality of the distribution by means of the test of Kolmogorov-Smirnov and the differences between the two populations of bee by means of tests parametric (t´Student) or nonparametric (U of Mann-Whitney), according to the type of distribution.

Although it is not usually lethal for the colony, it can reduce its population, hampering its development. This study is a review on the disease that presents a broad overview of its development, identification methods as well as ways to control it. Research shows that chalkbrood is associated with several factors and is most frequently found in colonies of Apis bees during the spring, when there is excess humidity and sudden temperature changes in the hive. Other factors such as viral or bacterial infection, the presence of the ectoparasite Varroa destructor, pesticide poisoning and poor nutrition of nurse bees can also affect its incidence and severity. Field diagnosis is made based on the presence of hardened mummified brood in the pupal stage, of white or bla...

Descriptive crossover study, conducted throughout 1991. Primary Care. Patients between 2 and 14 attending the Health Centre. We identified 349 children suffering from asthma (9.6% of the child population). 206 (59%) were male and 143 (41%), female. 45% of these children had shown symptoms suggesting asthma before their first birthday; 74% before they were 3; and 90% before 7. Family histories of asthma existed in 72%, of allergic rhinitis in 45% and atopic dermatitis in 17%. Out of the asthmatic children, 58% had allergic rhinitis and 20% atopic dermatitis. As to severity, 55% suffered light asthma, 31% moderate asthma and the remaining 14%, severe asthma. 79% had follow-up control of their asthma at the Health Centre. The rest were controlled by professionals outside the Centre (allergologists, pneumologists, hospital paediatricians etc.). 70% of ...
