Epidermal lesions and mortality caused by vibriosis in deep-sea Bahamian echinoids:a laboratory study

Epidermal lesions and mortality caused by vibriosis in deep-sea Bahamian echinoids: a laboratory study.

When significant mortality of the bathyal spatangoid echinoid Paleopneustes cristatus occurred under laboratory conditions, we investigated the cause and course of the disease by culturing and identifying internal pathogens, then experimentally infecting healthy urchins with isolates of the suspected disease organism. The pathogen was determined to be the gram-negative halophilic bacterium Vibr...

Slaughterhouse Study on the Prevalence and Pathological Lesions Caused by Dictyocaulus Viviparus Infection in Cattle and Water Buffaloes

Background:  Dictyocaulus viviparus nematode is the cause of severe bronchitis in dairy animals which lead to significant economic losses in the industry of this type of livestock. The present study aimed to determine the incidence of D. viviparous, a highly endemic parasite in cattle and water buffaloes in Guilan province, Iran. Materials & Methods:   Stool samples from 212 cows and 189 buf...

Socioeconomic Factors Associated With Mortality Rate Caused by Severe Stroke

Background: Stroke is one of the most important causes of disability-adjusted life years lost. Low socioeconomic status is associated with increased stroke-related morbidity and mortality. Objective: This study aimed to investigate in-hospital mortality rate caused by severe cases of ischemic and hemorrhagic stroke and its relationship with patients’ socioeconomic status. Materials and Method...

Light and vision in the deep-sea benthos: I. Bioluminescence at 500-1000 m depth in the Bahamian islands.

Bioluminescence is common and well studied in mesopelagic species. However, the extent of bioluminescence in benthic sites of similar depths is far less studied, although the relatively large eyes of benthic fish, crustaceans and cephalopods at bathyal depths suggest the presence of significant biogenic light. Using the Johnson-Sea-Link submersible, we collected numerous species of cnidarians, ...
