Antibiotic-Resistant Salmonella, isolated from cloacal swab samples from turtles in Guatemala

Cienc. tecnol. salud; 7 (2), 2020
Salmonellosis is a relevant public health threat worldwide. Reptiles are commonly involved in human cases. A microbiological survey was conducted from August to October 2018 to isolate Salmonella bacteria and de-termine if they were resistant to regularly used antibiotics in eight species of pet turtles ...

Existence of myodural bridge in the trachemys scripta elegans: indication of its important physiological function

Int. j. morphol; 37 (4), 2019
The myodural bridge (MDB) is confirmed that connecting the most of suboccipital muscles to the cervical dura mater through the posterior intervertebral spaces and widely exists in mammals and birds. In order to reveal whether the MDB is universally existing in amniota of vertebrates, we explored the exis...

Analysis of the green turtle esophagus Chelonia mydas (Linnaeus, 1758), Testudines, Cheloniidae

Int. j. morphol; 37 (4), 2019
The esophagus is a muscular tube whose function is to transport food from the mouth to the stomach and basically contain the same layers as the rest of the digestive tract. The morphological knowledge of structures involved in basic physiological processes in organisms is extremely important in the acqui...

Frequency of Clustered Regularly Interspaced Short Palindromic Repeats (CRISPRs) in non-clinical Enterococcus faecalis and Enterococcus faecium strains

Braz. j. biol; 79 (3), 2019
Abstract The fidelity of the genomes is defended by mechanism known as Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) systems. Three Type II CRISPR systems (CRISPR1- cas, CRISPR2 and CRISPR3-cas) have been identified in enterococci isolates from clinical and environmental samples. Th...

Morphology and biometry of the reproductive organs of adult males of Trachemys scripta elegans reared in São Paulo state, Brazil

Pesqui. vet. bras; 39 (7), 2019
Trachemys scripta elegans is an American underwater chelonian illegally marketed in Brazilian pet shops. When abandoned in nature, it compromises native species, threatening local biodiversity. However, little is known about the body development and structure of its reproductive tract. The objective of t...

Diatom assemblages associated with turtle carapaces in the Neotropical region

Rev. biol. trop; 66 (4), 2018
Abstract Few studies have explored the ecology and interrelationship with other organisms of the many endangered freshwater turtle species inhabiting the Neotropical region. The focus of the current study was to shed light on the relationship between Neotropical turtle carapaces and primary producers, in...

Influencia de la vigilancia en una zona rocosa dentro de un área marina protegida, Pacífico Central de Costa Rica

Rev. biol. trop; 66 (3), 2018
Resumen Los intermareales rocosos son sitios importantes para peces, aves, invertebrados y algas entre otros, que se utilizan para la extracción de recursos alimenticios para las comunidades costeras. Se presentan los resultados de la evaluación de una costa rocosa en el Pacífico Central de Costa Rica...

Plasma biochemistry values in wild female hawksbill turtle (Eretmochelys imbricata) during nesting in Mexican coast

To obtain plasma biochemistry values, blood was collected for 47 nesting females of apparently healthy Eretmochelys imbricata sea turtles using sodium heparin as an anticoagulant. Blood samples were collected in April-Jun for two years (nesting season). Hematologic characteristics, including packed cell ...

Atractis thapari (Nematoda, Atractidae) parasitizing Chelonoidis carbonarius and C. denticulatus (Testudinidae) in the state of Piauí, Brazil

Abstract Atractis thapari Petter, 1966, an atractid nematode, was collected parasitizing the large intestine of tortoises of the species Chelonoidis carbonarius (Spix, 1824) (Cc) and C. denticulatus (Linnaeus, 1766) (Cd) (Testudinidae) in the Zoobotanical Park of the municipality of Teresina, state of Pi...

Histomorphometric analysis of gonads of green turtles (chelonia mydas) stranded on the coast of Espírito Santo state, Brazil

Studies on reproduction in sea turtles are important due to its life cycle, migratory patterns, high juvenile mortality and environmental impacts. This study aimed to analyse histomorphometrically gonads of C. mydas from the coastline of the Espírito Santo State, Brazil. Ovaries and testicles were colle...
