  • Presencia de parásitos y enterobacterias en palomas ferales (Columba livia) en áreas urbanas en Envigado, Colombia
    2015
    Co-Authors: Pérez García Janeth, Monsalve Arcila Daniela, Márquez Camilo
    Abstract:

    Objective: to determine the presence of parasites andenterobacteria that are relevant to public health among feralpopulations of Columba livia inhabiting urban areas of theEnvigado municipality, Colombia. Methodology: a descriptivecross-sectional, prospective study in which 40 pigeons weretaken from six different areas. The feathers were assessedto determine Ectoparasitic Infestation. Likewise, coanal andcloacae swab was conducted and blood samples were takenfrom the axillar veins. Direct examination of feces with salineand iodine solution was performed, the flotation techniquewas used and the Ziehl-Neelsen staining tests were conducted.Haemoparasites were diagnosed with the thick smear method,Wright and Hemacolor® staining. The API 20e® systemwas used for enterobacteria. Descriptive statistic procedureswere carried out along with a correlation analysis betweenhaemoparasites and ectoparasites. Results: Escherichia coli(95%), Haemoproteus spp. (73%), Columbicola columbae(64%), oocysts compatible with Eimeria spp. (55%),Pseudolynchia canariensis (52%), Trichomona spp. (40%),Capillaria spp. (28%), Menopon gallinae (24%), Ascaridiaspp. (8%), and a case of Enterobacter cloacae. Additionally,the presence of Ornithonyssus bursa was detected in the nestsof some of the birds sampled in this study. Discussion: In spiteof the reports of sparse cases of infection in humans found inthe literature, the microorganisms isolated in this study havea low risk of transmission in humans. However, they maybecome a veterinary public health problem since they are apotential source of infection for the urban wildlife with whichthey share water, food and refuge. Conclusion: The mostimportant percentage was that of oocysts compatible withEimeria spp (55%) and enterobacteria such as E. coli (95%).The presence of Ornithonyssus bursa in the nests evidences apotentially zoonotic pathogen responsible for dermatologicallesions in humans. Objetivo: diagnosticar la presencia de parásitos y enterobacterias de importancia en Salud Pública en poblaciones ferales de Columba livia en zonas urbanas del municipio de Envigado, Colombia. Metodología: Estudio descriptivo transversal prospectivo con cuarenta palomas en seis lugares diferentes. Se evaluó plumaje para determinar ectoparásitos, hisopado coanal y cloacal, y muestra de sangre de la vena axilar. Se realizó examen directo con solución salina y yodada; técnica de flotación y tinción de Ziehl-Neelsen. El diagnóstico de hemoparásitos se efectuó mediante método de gota gruesa, coloración de Wright y tinción Hemacolor®. Se utilizó API 20e® para Enterobacterias. Se realizó estadística descriptiva y análisis de correlación entre hemoparásitos y ectoparásitos. Resultados: Escherichia coli (95%), Haemoproteus spp. (73%), Columbicola columbae (64%), ooquistes compatibles con Eimeria spp. (55%), Pseudolynchia canariensis (52%), Trichomona spp. (40%), Capillaria spp. (28%), Menopon gallinae (24%), Ascaridia spp. (8%), y un caso de Enterobacter cloacae. Se identificó la presencia de Ornithonyssus bursa en nidos de algunas de las aves muestreadas. Discusión: Aunque se han presentado reportes de casos eventuales de ellos en personas dentro de la revisión de literatura, los microorganismos aislados tienen un bajo riesgo de transmisión en humanos; sin embargo pueden convertirse en un problema de salud pública veterinaria al ser potenciales fuentes de infección a la fauna silvestre urbana con quienes comparten albergue, fuentes de agua y alimento. Conclusión: El mayor porcentaje fue ooquistes compatibles con Eimeria spp (55%) y enterobacterias como E. coli (95%). Ornithonyssus bursa en las palomeras evidencia la presencia de un patógeno potencialmente zoonótico, causante de lesiones dérmicas en humanos.

  • Secondary sexual ornaments and ectoparasites in the barn swallow (Hirundo rustica)
    2017
    Co-Authors: Wichová Eliška
    Abstract:

    Parasites could represent an important evolutionary driver and play an important role in a sexual selection. In the mate selection process, females use secondary sexual ornaments, which may reflect the parasite load and health condition of males. Females would benefit from choosing males with the most extravagant sexual characters, which indicate low levels of parasite Infestation. A popular model species for sexual selection study is the barn swallow (Hirundo rustica). However there are no recent studies investigating the relationship between the level of the Ectoparasitic Infestation and the ornamentation of the barn swallow. Results of this thesis, based on analysis of ectoparasite load in 204 individuals show, that the level of Infestation by feather mites is positively correlated with outermost tail feathers and the intensity of feather holes is negatively correlated with a breast coloration. The relationship between the abundance of ectoparasites and white tail spots was not found. The effect of ectoparasites on the survival of individuals or the nest initiation date was not observed. A possitive relationship between the individual seasonal change in feather mites Infestation and brood size was detected. This implies a potential trade-off between the investments into parental care and defence..

Samice se v procesu volby partnera orientují pomocí druhotných pohlavních znaků, které pravdivě vypovídají o zdravotním stavu samců. Samice tak mohou získat výhodu díky volbě partnera s nejvýraznějšími pohlavními znaky, které odráží stupeň zatížení parazity. Modelovým druhem pro studium pohlavního výběru je vlaštovka obecná (Hirundo rustica). Překvapivým faktem je, že neexistují novější práce zaměřené na vztah mezi množstvím ektoparazitů a ornamentací u vlaštovky obecné. Výsledky této práce založené na analýze ektoparazitů u 204 jedinců ukazují, že množství péřových roztočů pozitivně koreluje s délkou rýdovacích per, a zároveň hustota děr v opeření způsobených všenkami negativně koreluje se sytostí hrdla. Nebyl nalezen vztah mezi množstvím ektoparazitů a plochou bílých skvrn na ocase. Zároveň nebyl pozorován vliv ektoparazitů na přežití jedinců do další sezony či časnost hnízdění. Byl však pozorován pozitivní vztah mezi počtem mláďat v hnízdě a sezónní změnou v zatížení péřovými roztoči dospělců. Toto zjištění by mohlo vypovídat o existenci trade-off mezi investicí do počtu mláďat a investicí do obrany vůči ektoparazitům. Stupeň zatížení péřovými roztoči pozitivně koreloval s poměrem...Katedra zoologieDepartment of ZoologyPřírodovědecká fakultaFaculty of Scienc

  • prevalence and risk factors associated with ectoparasite Infestation of buffaloes in an amazonian ecosystem
    Parasites & Vectors, 2018

    Abstract:

    The water buffalo (Bubalus bubalis) is well adapted in some regions of the Amazon. Of all Brazilian states, Para contains the largest number of this species, with 510,000 animals, approximately 38% of the Brazilian buffaloes. Despite the socioeconomic importance of bubaline farming in the northern region, little is known about the prevalence of ectoparasites that affect buffalo herds. This study aimed to identify the species of buffalo ectoparasites in the municipality of Santarem, Para, and to determine possible risk factors related to Ectoparasitic Infestation. A cross-sectional study was conducted by sampling 60 rural properties and 621 buffaloes for ectoparasites. When present, ectoparasites were collected for subsequent identification. Of all the animals sampled, 18.5% (115/621) had ectoparasites, 7.8% (49/621) had ticks from the species Rhipicephalus (Boophilus) microplus and Amblyomma cajennense (sensu stricto), and 11.5% (72/621) had lice from the Haematopinus tuberculatus species. Six animals presented mixed Infestations of ticks and lice. Among the sampled farms, 51.6% (31/60) had at least one animal infested with ectoparasites. The prevalence of ticks and lice on buffaloes was associated with the farm site, with higher prevalence (11.5% ticks, 15.4% lice) in animals at dry land (OR: 16.7 and 5.7 for ticks and lice, respectively) when compared with floodplains (0.5% ticks, 3.4% lice). Buffaloes aged 1 to 12 months had more ticks whereas buffaloes aged 13 to 24 months had more lice (P < 0.05). Buffaloes bred in the municipality of Santarem present different levels of tick and lice Infestation according to the direct influence of Amazon ecosystem characteristics. The floodplain environment, widely used for buffalo farming, contributes toward minor ectoparasite Infestations in these animals.
