“…Methylobacterium and Streptococcus have been previously detected in arthropods and in vertebrates, and may thus be vector-borne bacteria as well. Diaphorobacter was previously found in arthropods but not in vertebrate blood; it is not known as a member of the skin or eye microbiome (Cullen, 2003;Coster et al, 2008;Montiani-Ferreira et al, 2008;Scharschmidt et al, 2009;Grice and Segre, 2011;Hoffmann et al, 2014;Meekins et al, 2014;Tomic-Canic et al, 2014), and therefore its occurrence in the gerbil blood is probably not a result of contamination and deserves further investigation. Seven additional phylotypes were detected in 2-4 samples, representing five genera.…”

Similarities and seasonal variations in bacterial communities from the blood of rodents and from their flea vectors

et al. 2015

Vector-borne microbes are subject to the ecological constraints of two distinct microenvironments: that in the arthropod vector and that in the blood of its vertebrate host. Because the structure of bacterial communities in these two microenvironments may substantially affect the abundance of vector-borne microbes, it is important to understand the relationship between bacterial communities in both microenvironments and the determinants that shape them. We used pyrosequencing analyses to compare the structure of bacterial communities in Synosternus cleopatrae fleas and in the blood of their Gerbillus andersoni hosts. We also monitored the interindividual and seasonal variability in these bacterial communities by sampling the same individual wild rodents during the spring and again during the summer. We show that the bacterial communities in each sample type (blood, female flea or male flea) had a similar phylotype composition among host individuals, but exhibited seasonal variability that was not directly associated with host characteristics. The structure of bacterial communities in male fleas and in the blood of their rodent hosts was remarkably similar and was dominated by flea-borne Bartonella and Mycoplasma phylotypes. A lower abundance of flea-borne bacteria and the presence of Wolbachia phylotypes distinguished bacterial communities in female fleas from those in male fleas and in rodent blood. These results suggest that the overall abundance of a certain vector-borne microbe is more likely to be determined by the abundance of endosymbiotic bacteria in the vector, abundance of other vector-borne microbes co-occurring in the vector and in the host blood and by seasonal changes, than by host characteristics.

RESUMO.-[Pressão intraocular e teste lacrimal de Schirmer em lobos-guará (Chrysocyon brachyurus).]O objetivo deste estudo foi estabelecer dados de referên-cia sobre a produção lacrimal (STT-1) e pressão intraocular (PIO) em lobos-guará em cativeiro. Foram utilizados 10 lobos-guará, saudáveis e adultos. Os animais foram contidos com cambão e mordaça e mantidos em decúbito lateral esquerdo. O TLS foi realizado no terço médio da pálpebra inferior, durante um minuto. A córnea foi dessensibilizada e a PIO mensurada com tonopen. A média do TLS-1 dos olhos direitos e esquerdo foi 11±5mm/ min, não havendo diferença significativa entre os olhos (p=0,960). A média da PIO dos olhos direitos e esquerdo foi 20±6mmHg, não observando diferença entre os olhos direitos e esquerdos (p=0,836). Média STT-1 foi menor do que, e PIO foi o mesmo que os níveis normais em cães. Não houve diferença estatística na idade dos animais e valores STT-1 e da PIO. No presente trabalho, os níveis médios de guará STT-1 foram mais baixos em comparação com as observadas nos cães, enquanto que a pressão intraocular foi a mesma nos lobos guará como em cães. Devido ao aumento da incidência na prestação de cuidados de emergência para vítimas de lobos-guará atropelamentos e incêndios, determinar os valores de referência dos parâmetros oculares podem melhorar o diagnóstico correto e tratamento de doenças. The purpose of this study was to establish baseline data on lacrimal quantity (STT-1) and intraocular pressure (IOP) in captive maned wolves. Ten healthy adult maned wolves were contained with a snare pole and muzzle and kept in decubitus of the left side. STT-1 measurement was performed on the lateral third of the lower conjunctival sac for one minute. The cornea was desensitized and intraocular pressure was measured with an tonopen. Average STT-1 in both eyes was 11±5mm.min -1 , with no statistical difference between the left and right eye (p=0.960). Average IOP in both eyes was 20±6mmHg, with no statistical difference between the left and right eye (p=0.836). Average STT-1 was lower than, and IOP was the same as normal levels found in dogs. There was no statistical difference in the age of the animals, and STT-1 and IOP values. In the present paper, average maned wolf STT-1 levels were lower compared with those found in dogs, while the IOP was the same in maned wolves as in dogs. Due to the increased incidence in providing emergency care for maned wolf victims of road kill and fires, determination reference values of ocular parameters may improve the correct diagnosis and treatment of the disease.

“…There are several studies that have identified the resident microbiota of the conjunctiva and all showed the prevalence of Gram-positive, even in different animal species, such as dogs (Anvisa, 2013), horses, capybara, capuchin monkey, domestic ferret (Montiani-Ferreira et al, 2006;2008a;2008b) or even aquatic habitat animals as beavers, showed the same profile (Cullen, 2003).…”

The objective of this study was to identify the main microorganisms associated with ophthalmic infections and determine the resistance profile of these isolates against antimicrobial drugs. 26 bacterial isolates from 18 canine ophthalmic infections were submited to the phenotypic resistance profile for 36 drugs of 12 classes of antimicrobials, research of multidrug-resistant strains with importance in public health and detection of Staphylococcus mecA gene by PCR. The bacterial isolates were identified as Staphylococcus spp. (n = 18), Enterococcus spp. (n = 1), enterobacteria (n = 6) and Pseudomonas spp. (n = 1). The percentage of resistance and intermediate resistance were 42.48% (n = 325). Considering separate antimicrobials drugs, 18 isolates were characterized by multidrug resistant, while by the assesment of resistance to class, 20 isolates were multiresistant. In the phenotypic detection, 61.11% (11/18) of Staphylococcus spp. were predicted by Methicillin-Resistant Staphyloccus (MRS), whereas the genotypic detection, 38.89% (7/18) were carriers of the mecA gene. Two enterobacterias were considered producers of expectro Extended of Betalactamase (ESBL). EUCAST was more reliable for detecting MRS strains than the CLSI. The present study detected multiresistant isolates of great importance and are involved in cases of public health, such as MRS, MRSMLSb, ESBL, very important to be readily identified and controled so as to prevent the spread of this type of resistance.
