West Nile Virus (WNV) is a zoonotic arbovirus worldwide spread. Seasonal WNV outbreaks occur in the Mediterranean basin since late 1990's with ever-increasing incidence. In Southern Spain endemic, as disease foci - caused by lineage 1 (WNV-L1) strains every year. On contrary, WNV-L2 dominant Europe, so most European sequences available belong to this lineage, WNV-L1 being still scarce.
We explore the presence of zoonotic flaviviruses (West Nile virus (WNV) and Usutu (USUV)) neutralizing antibodies in rarely studied passerine bird species. report, for first time Europe, WNV-specific red avadavat cetti's warbler, USUV yellow-crowned bishop. The evidence WNV circulating resident migratory species has implications both animal public health. Future outbreaks avian reservoir hosts may occur passerines should be considered as priority target flavivirus surveillance programmes.
Abstract Understanding how life is adapting to urban environments represents an important challenge in evolutionary biology. Here we investigate a widely cited example of adaptation, Culex pipiens form molestus , also known as the London Underground Mosquito. Population genomic analysis ∼350 contemporary and historical samples counter popular hypothesis that originated belowground less than 200 years ago. Instead, show first adapted human aboveground Middle East over course >1000 years,...
Summary Food safety regulations require the control of presence protozoa in meats destined for human consumption. Wild boar ( Sus scrofa ) meat may constitute a source zoonoses. A 23.8% (688/2881) seroprevalence anti‐ Toxoplasma gondii antibodies and 72.2% (662/910) Sarcocystis sarcocysts prevalence were detected among wild boars hunted Southwestern areas Spain. Identity spp. was performed by RFLP ‐ PCR sequencing, detecting S. miescheriana (7/8) zoonotic suihominis (1/8). Risk assessment...
West Nile virus (WNV) is a mosquito-borne emerging in Europe with capacity to cause neurological complications such as encephalitis or meningoencephalitis humans, birds equids. In Spain, WNV actively circulating mosquitoes, and horses different regions, but never has been deeply studied Extremadura. Therefore, the aim of this study was evaluate seroprevalence equids those areas analyse risk factors associated exposure virus. A total 199 out 725 presented antibodies against by competition...
We used PCR to detect Toxoplasma gondii in the principal game species southwestern Spain. detected T. 32.2% of animals tested. Prevalences varied from 14.7% wild boar (Sus scrofa) 51.2% red fox (Vulpes vulpes). The most prevalent genotype was type II (50.0%), followed by III (20.6%) and I (5.9%). Mixed infections (11.8%) were (types I+III) II+III). Polymorphic strains several species. high prevalence genetic variability shown could have implications for infection farm humans.
This study updates the diversity, distribution, and seasonal trends of mosquitoes in a western region Spain, assesses ecological determinants Culex pipiens s.l., determines form composition Cx. s.s. populations. A total 1,495 16 species was collected during 2012–2013, which s.l. theileri were most abundant. Five new records for An. maculipennis s.s., Orthopodomyia pulcripalpis, Aedes (Ochlerotatus) punctor, europaeus, modestus found this region. density varied across weather habitat...
Malaria remains one of the most important infectious diseases globally due to its high incidence and mortality rates. The influx infected cases from endemic non-endemic malaria regions like Europe has resulted in a public health concern over sporadic local outbreaks. This is facilitated by continued presence competent Anopheles vectors countries.
Culex univittatus and perexiguus mosquitoes (Diptera: Culicidae) are competent arbovirus vectors, but with unclear morphological differentiation. In Europe, in the Iberian Peninsula particular, presence of either or both species is controversial. However, order to conduct adequate surveillance for arboviruses this region, it crucial clarify whether Cx. present not, as well critically assess existing differentiation tools. This study aimed situation, by molecular phylogenetic comparison...
We analyzed 927 wild boars (Sus scrofa) in southwestern Spain during the hunting seasons of 2004/2005 to 2008/2009. Respiratory tracts were examined for lung nematodes (Metastrongylus spp.). The prevalence Metastrongylus spp. was 41.1%. most frequently isolated species apri (71.4%), pudendotectus (28.0%), and salmi (0.6%). Prevalence infection intensity greater young animals (<1 yr old) than older animals. There no significant differences between sexes. higher areas high altitude rainfall.
Abstract A study was performed to evaluate the implication of Protophormia terraenovae larvae as a surgical therapy for wounded skin. Three groups sheep (n = 25) were considered based on larval doses. Groups 1 and 2 artificially infested with low high concentrations L1 stage P. terraenovae, respectively, group 0 served control. Skin biopsies taken at 4 14 d postinfestation (D.P.If). histopathological carried out lesions score, numbers eosinophils mast cells, an immunohistochemical analysis...
Usutu virus (USUV) is an emerging zoonotic arbovirus that has caused increasing number of animal and human cases in Europe recent years. Understanding the vector species avian hosts involved USUV enzootic cycle area active circulation vital to anticipate potential outbreaks. Mosquitoes were captured 2020, while wild birds sampled both 2020 2021 Extremadura, southwestern Spain. The presence mosquito vectors was assessed by a real-time reverse transcription-polymerase chain reaction (rRT-PCR)...
Human and animal vector-borne diseases, particularly mosquito-borne are emerging or re-emerging worldwide. Six Aedes invasive mosquito (AIM) species were introduced to Europe since the 1970s: aegypti, Ae. albopictus, japonicus, koreicus, atropalpus triseriatus. Here, we report results of AIMSurv2020, first pan-European surveillance effort for AIMs. Implemented by 42 volunteer teams from 24 countries. And presented in form a dataset named "AIMSurv Invasive Mosquito harmonized Europe. AIM-COST...
Background Vector-borne diseases like West Nile virus (WNV) pose a global health challenge, with rising incidence and distribution. Culex mosquitoes are crucial WNV vectors. Avian species composition bird community diversity, along vector communities, influence transmission patterns. However, limited knowledge exists on their impact in southwestern Spain, an area active circulation wild birds, mosquitoes, humans.
Congenital toxoplasmosis has been little described in wild animals. We report a case of vertical transmission boar (Sus scrofa). Necropsy and histopathologic examination pregnant female her three fetuses revealed all to have lesions compatible with acute toxoplasmosis. Nested polymerase chain reaction B1 gene detected Toxoplasma gondii maternal (heart diaphragm) fetal (central nervous system, retina, optic nerve, heart, lung, tongue, samples. The mother had mixed infection T. types I III....
Haematophagous insects cause major economic losses by both direct damage and the transmission of pathogens. However, biting Diptera species in Caribbean region have been poorly documented. During 2021, CDC downdraft suction traps with UV light were employed to assess occurrence blood meal sources across three different habitats Dominican Republic. Eighteen mosquitoes (n = 274), six Culicoides 803), two black fly 2), one muscid 25) identified at species-level morphology and/or molecular...
