The objective of this study is to describe the genetic population structure and demographic history of the endangered marine fish, Epinephelus marginatus, within Malta's Fisheries Management Zone for the purpose of localised conservation planning. Epinephelus marginatus is a long-lived, sedentary, reef-associated protogynous hermaphrodite with high commercial and recreational value that is at r...

In order to inventory the metazoan endoparasites of Serrasalmus marginatus, 91 specimens were examined. They were captured in the Negro River in Pantanal wetland, State of Mato Grosso do Sul, Central-Western Brazil, from October 2007 to August 2008. Parasites of six taxa were recovered: Procamallanus (Spirocamallanus) inopinatus, Contracaecum sp. (Nematoda), metacercarial type Diplostomulum (Di...

The saliva of Rhynocoris marginatus consists of amylase, invertase, trehalase, protease, acid phosphatase, alkaline phosphatase, phospholipase, lipase, trypsin, hyaluronidase, and esterase. All enzyme activities were significantly higher in the saliva of female R. marginatus when compared to the saliva of male individuals. The saliva was analyzed by tricine SDS/PAGE, sephadex column chromatogra...

To the Editor: Rickettsia slovaca is a bacterium that infects Dermacentor marginatus ticks in central and western Europe. First detected in ticks, the bacterium was subsequently identified with genomic amplification by using polymerase chain reaction (PCR) followed by sequencing in a skin biopsy from a French patient (1). We describe the first isolation of the organism from a patient. A 79-year...

Effect of temperature on the life history of the mealybug Paracoccus marginatus Williams & Granara de Willink (Hemiptera: Pseudococcidae) was investigated in the laboratory. P. marginatus was able to develop and complete its life cycle at 18, 20, 25, and 30 +/- 1 degrees C. At 15, 34, and 35 degrees C, the eggs hatched after 27.5, 5.9, and 5.5 d of incubation, respectively, but further developm...

Herbivory is a fundamental process determining reef resilience, and while algal farming damselfishes can help shape benthic assemblages, an understanding of their contribution to areas outside of defended territories is relatively unexplored. Here, we demonstrate how the farming damselfish Stegastes marginatus plays a dual role in benthic structuring by 1) contributing to persistence of the inv...

This study was aimed to determine the infection rate and vectors of Theileria lestoquardi in goats from West Azerbaijan province, Iran. A total of 400 blood samples were collected from 40 randomly selected flocks in the study area from June to September, 2014. Out of 400 blood samples examined using microscopic examination, a number of 14 goats (3.50%) were positive for Theileria spp., whereas ...

This study describes the epidemiological, clinical, and microbiological characteristics of a new tick-borne disease in Spain-Dermacentor-borne necrosis erythema lymphadenopathy (DEBONEL). The clinical presentations include an eschar at the site of the tick bite, surrounded by an erythema and painful regional lymphadenopathy. The disease appears during the colder months and its vector is Dermace...

Hard ticks (Acari: Ixodidae) are important obligatory blood feeding external parasites of human and animals. There have been a lot of studies on taxonomy of Iranian ixodidae. On the basis of morphological features found basically in adult male. There are problems in tick identification due to their intraspecific variations and morphological changes of the surface body of ticks after blood feedi...
