Purpose: Tick diversity in Algeria has garnered increasing interest due to its implications for animal health and zoonotic diseases. Recent reports of abnormal ulcerative lesions in goats and sheep in the Cheria region of northeastern Algeria have raised concerns about a potential association with tick infestations. The aim of this study is to hypothesize the potential involvement of ticks in these unusual lesions.

Background: Ticks are hematophagous ectoparasites that feed on the skin surface of their host. Subcutaneous localizations of ticks have predominantly been associated with red foxes, documenting new cases still brings new and potentially valuable data for tackling this unusual situation. The objective of this study is to report the presence of subcutaneous ticks in a new host and on a new continent.

Background: Ticks are hematophagous arthropods acting as important vectors for several microorganisms. Ticks have an important role in the epidemiology of numerous diseases from a public health standpoint. In Algeria, knowledge of tick-borne associated microorganisms is limited.

As ectoparasites and efficient vectors of pathogens fleas constitute a source of nuisance for animals as well as a major issue for public health in Algeria. In this study, a molecular survey has been conducted to investigate the presence of pathogens in fleas infesting domestic and wild carnivores in the central north and eastern north and south of Algeria. The molecular screening that targeted Acanthocheilonema reconditum, Bartonella spp.

Fleas (Siphonaptera) are medically and veterinary important ectoparasites known to infest a wide range of host species. This study presents a systematic review complemented by new data on the diversity of flea species and host associations in Algeria. 198 mammals were examined, including previously understudied hosts such as sheep, red foxes, fennec foxes, and golden African wolves.

Nuisance, allergy, and vector role: mosquitoes are responsible for numerous inconveniences. Several strategies have been employed to fight against this confirmed vector. To record the diversity of mosquito vectors in Camargue (France) and assess the effectiveness of the Qista trap, six BAMs were deployed as a belt barrier to protect the Espeyran Castle (Saint-Gilles, Camargue).

Fleas are an important member of the North African entomofauna. An understanding of the risks of flea-borne diseases to public and veterinary health can be gained with surveys of their abundance, distribution, and hosts. The aims of this study were to make an initial assessment of flea (Siphonaptera) species collected from a selected number of mammalian hosts in Algeria and debate their medical and veterinary importance.

The sheep ked, Melophagus ovinus, and the forest fly, Hippobosca equina, are parasitic dipteran insects of veterinary importance. As hematophagous insects, they might be considered as potential vectors of diseases which may be transmissible to humans and animals. The purpose of this study was to present initial primary data about these two species in Algeria.

Recent studies have reported the reliability of MALDI-TOF MS for arthropod identification, including fresh or alcohol-preserved ticks based on leg-derived mass spectra. The aim of this study was to evaluate the performance of MALDI-TOF MS for the identification of alcohol-preserved Algerian ticks collected from different domestic and wild hosts. Secondly, we conducted a molecular survey to detect the presence of bacterial DNA in all ticks that were previously subjected to MALDI-TOF MS.

Using qPCR, standard PCR and/or sequencing, we investigated the presence of tick-associated microorganisms in ticks and blood from sheep and goats from Souk Ahras, Algeria. Borrelia theileri, was detected in (7/120, 5.8%) blood from sheep and (13/120, 10.

Slaughterhouse samples were analysed over a two-year period (September 2010-August 2012) in Jijel (northeastern Algeria) in order to determine seasonal variations in the prevalence and intensity of bovine paramphistomosis in a Mediterranean climate and identify paramphistome species using molecular biology. In spring and summer, significantly higher prevalences and lower parasite burdens were noted in bull calves, thus indicating an effect of season on these parameters. In contrast, the differences among seasonal prevalences or among seasonal parasite burdens were not significant in the case of old cows.
