INTRODUCTION Giardia intestinalis is the most important and common diarrhea-causing parasitic protozoa worldwide with growing clinical relevance in public health. There are many documented cases of G. intestinalis resistance to metronidazole (MZ). Pyruvate: ferredoxin oxidoreductase (PFOR), the membrane-localized enzyme, plays a key role in the development of resistance to drugs. The aim of the...

The tunicate Ciona intestinalis is an opportunistic invader with high potential for causing economic losses in aquaculture centers. Recent phylogenetic and population genetic analysis support the existence of a genetic complex described as C. intestinalis with two main dominant species (sp A and B) occurring worldwide. In Chile, the species has been observed around 30°S of latitude, but no offi...

the antibacterial and antioxidant activities of methanol and acetone extracts of three marine algae, including hypnea hamulosa, gracilaria corticata and enteromorpha intestinalis wereinvestigated.antioxidant activities were determined by means of total antioxidant capacity, total phenolic compounds, dpph radical scavenging activity and ferric reducing antioxidant power. antibacterial activity w...

The invasive tunicate species Ciona intestinalis (Linnaeus, 1767) has had an economic impact on the aquaculture of the blue mussel Mytilus edulis (Linnaeus, 1758) in Prince Edward Island (PEI). This tunicate fouls mussel socks suspended on long lines in the water and reduces both weight and numbers of mussels, decreasing overall productivity. This study determined the relative effects of high p...

Pneumatosis intestinalis (PI) is an uncommon but important condition characterized by the accumulation of gases in the submucosa or subserosa of the gastrointestinal wall. The clinical course of PI represents a wide spectrum of conditions and outcomes that range from benign to life-threatening. Although controversy exists about the exact cause of PI, mucosal integrity, intraluminal pressure, ga...

A description of the last larval instar (based on exuvium) of Anthrenus latefasciatus Reitter, 1892 (Coleoptera: Dermestidae) is presented. New morphological characters of A. latefasciatus larvae such as general morphology of antenna, epipharynx, mandibula, maxilla, ligula with labial palpi, hastisetae, legs, terga and condition of antecostal suture are documented and discussed. General morphol...
