Dermanyssus gallinae (De Geer, 1778), poultry red mite or chicken mite, is haematophagous poultry ectoparasite. In poultry flocks small populations of chicken mite usually remain undetected. In order to supplement existing diagnostics we have investigated the method for its early detection. Investigation was carried out on 13 flocks, during two-year period, throughout Serbia and Montenegro. We have established that method for early detection of chicken mite can: improve the efficiency of existing diagnostic methods, that it is simple and reduces the period when parasites are hidden since it enables detection of small number of parasites before the population becomes visible. We recommend it to poultry farmers for regular control of the flock and control of the new flock, to veterinarians in poultry production as supplement to diagnostic methods: when suspecting the presence of Dermanyssosis in order to achieve early differential diagnostics, sampling of small number of chicken mite, monitoring the movement of the population and effect of the treatment, coming to conclusion regarding the effect of the disease control and as element of the forensic evaluation method. .

The Impact

Abstract Poultry red mite (PRM), Dermanyssus gallinae, causes egg drop production, anemia and can be a vector in transmitting diseases. The PRM control mainly focuses on usage of the conventional chemical biocides. The objective of this study was to analyze the farmers’ perception regarding the impact, management and control of PRM in Macedonian layer farms. The data were collected with direct on-site visits using a unified questionnaire. In total, 29 poultry farms (28% of farms in the country), all with conventional cages, were part of this study. The data were analyzed by descriptive statistics, inferential statistics and Naïve Bayes Classifier technique. In 30% of the poultry farms the farmers had observed that the flock was infested with PRM. In total, 32 different treatments against PRM were reported from the farmers, and three of them were non-biocide treatments. The most used biocides (17% of the farms) were crude oil, Formalin, Neopitroid® and disinfectants. The highest agreement regarding biocides application among the farms (38%) was before the production starts. Most of the farmers applied biocides routinely, before the infestation is evident (75%). The median costs for PRM treatment were 175€ per flock, higher in the infested farms 493±677€ compared to non - infested 100±71€, p<0.05. None of the Macedonian farmers included in the study was using monitoring method for PRM infestation, contributing to poor data records. This study highlights the need of developing unified strategy for PRM control included in the Integrated Pest Management in poultry layer farms.

Technological solutions and environmental conditions have a significant impact on infestation intensity and the problems around D. gallinae control. Changes in keeping laying hens in EU, in terms of D. gallinae influence, have not led to the welfare of the layers. On the contrary, they have contributed to the spreading of disease, have worsened conditions for control and accentuated harmful consequences. Apart from the poultry, these changes have also had a negative impact on the welfare of humans, through a toxicological and zootonic risk, and economic damages. Conventional cages so far provide the most appropriate environment for D. gallinae control. Opportunities for improving, even solving the problem of D. gallinae control in egg production do exist, however they require a changing the entire approach hitherto.

African swine fever is a highly contagious global disease caused by the African swine fever virus. Since African swine fever (ASF) was introduced to Georgia in 2007, it has spread to many Eurasian countries at an extremely fast speed. It has recently spread to China and other major pig-producing countries in southeast Asia, threatening global pork production and food security. As there is no available vaccine at present, prevention and control must be carried out based on early detection and strict biosecurity measures. Early detection should be based on the rapid identification of the disease on the spot, followed by laboratory diagnosis, which is essential for disease control. In this review, we introduced the prevalence, transmission routes, eradication control strategies, and diagnostic methods of ASF. We reviewed the various methods of diagnosing ASF, focusing on their technical characteristics and clinical test results. Finally, we give some prospects for improving the diagnosis strategy in the future.

It also contains the method testing results and presents the prospects and risks teachers could face while applying the method in a higher education institution. The purpose of this study is to find out the prospects and risks of applying the method for increasing the level of self-organisation in students and to determine the ways of reducing the risks. Methodology. The author points out the learning approaches which were the basis of developing the method and describes diagnostic methods for determining students’ self-organisation levels. The work focused on increasing each student’s initial level consists of a theoretical and a practical part and includes project activities on creating a study guide. The results of the study.

Dermanyssus gallinae (the poultry red mite, PRM) is an important ectoparasite in the laying hen industry. PRM can also infest humans, causing gamasoidosis, which is manifested as skin lesions characterized by rash and itching. Recently, there has been an increase in the reported number of human infestation cases with D. gallinae, mostly associated with the proliferation of pigeons in cities where they build their nests. The human form of the disease has not been linked to swallows (Hirundinidae) before. In this report, we describe an incident of human gamasoidosis linked to a nest of swallows built on the window ledge of an apartment in the island of Kefalonia, Greece. Mites were identified as D. gallinae using morphological keys and amplifying the Cytochrome C oxidase subunit I (COI) gene by PCR. Bayesian phylogenetic analysis and median-joining network supported the identification of three PRM haplogroups and the haplotype isolated from swallows was identical to three PRM sequences isolated from hens in Portugal. The patient was treated with topical corticosteroids, while the house was sprayed with deltamethrin. After one week, the mites disappeared and clinical symptoms subsided. The current study is the first report of human gamasoidosis from PRM found in swallows’ nest.
