This infection can lead to serious outcomes such as abortion, neonatal death, or fetal abnormalities. Camels play a crucial role in the economic, ecological, and social landscapes of various regions, particularly in the Middle East, highlighting the importance of close health monitoring and disease screening. Hence in this study, sera from 409 dromedary camels (39 males and 370 females) were examined for T. gondii IgG antibodies using the Modified Agglutination Test (MAT). Both univariable and multivariable statistical analyses were performed using SPSS to identify the risk factors. A seroprevalence of 32% was found with 74% of the reactive specimens exhibiting a MAT titer ≤ 80. Univariate analysis ruled out sex and season as significant risk factors. Multivariable analysis confirmed age and area as statistically significant factors (P value < 0.05) associated with T. gondii seropositivity in camels. Overall, the finding of the present study confirms that T. gondii is prevalent and widely distributed in camels in suburban areas of Qatar. Given the veterinary and economic implications, there is an urgent need for further investigations into the infection's risk factors and its zoonotic impact.","PeriodicalId":16659,"journal":{"name":"Journal of Parasitology","volume":"111 1","pages":"70-76"},"PeriodicalIF":1.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143408480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are 503 recognized species divided into about 30 genera, with 75% of species belonging to the 2 largest genera, Caligus and Lepeophtheirus. More than 30 caligid species are known to cause serious pathologic changes as ectoparasites in marine teleost aquaculture. This study was undertaken to provide a key to the valid genera of Caligidae, to examine their morphology in new detail with confocal laser scanning microscopy, and to review uncertainties concerning boundaries between several genera. There have been several substantial changes to the taxonomy of Caligidae over the last decade: Metacaligus, Sciaenophilus, and Sinocaligus have been synonymized with Caligus and the validity of Midias has been questioned. Here, we formally propose that Midias and Markevichus are junior subjective synonyms of Caligus. In total, we recognize 27 valid genera; provide a key to these genera; present confocal laser scanning micrographs for 25 of the genera, many of which have never been imaged before; and highlight helpful diagnostic features used in the key. We also discuss some concerns regarding the generic boundaries separating Belizia, Caritus, Parapetalus, Parechetus, Pseudechetus, and Synestius from Caligus and those separating Anuretes, Pseudanuretes, and Mappates from Lepeophtheirus.","PeriodicalId":16659,"journal":{"name":"Journal of Parasitology","volume":"111 1","pages":"10-25"},"PeriodicalIF":1.1,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144957987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analysis of cystic contents in these patients shows that diminished scolex vitality is more common in patients with cysto-biliary fistulas. This study aims to demonstrate the scolicidal effects of bile on Echinococcus granulosus (EG) scolices at various bile concentrations and over specific periods. The time- and concentration-based scolicidal potency was analyzed in EG scolex samples obtained from HC patients. The integrity of the cyst wall and the scolicidal effect of the contents were evaluated using a vital staining technique with 0.1% eosin. Bile samples were collected from patients with cholelithiasis who were scheduled for surgery. Scolicidal efficacy of 100% was observed in all samples at the 1/4 bile concentration after 10 min and at the 1/8 concentration after 60 min. At a 1/16 concentration, scolicidal efficacy was 66% at 1 min, 89% at 10 min, 93% at 30 min, and 98% at 60 min. At a 1/32 bile concentration, scolicidal efficacy was 59% at 1 min, 68% at 10 min, 89% at 30 min, and 95% t 60 min. At a 1/64 concentration, the scolicidal efficacy was 53% at 1 min, 58% at 10 min, 77% at 30 min, and 93% at 60 min. After 1 hr, reasonable scolicidal efficacy was determined up to a 1/64 concentration; however, significant decreases in scolicidal efficacy were observed at 1/128 and 1/256 bile concentrations. Theoretically, bile, which is an endogenous secretion, can be used as a suitable and potent scolicidal agent.

Recent molecular analyses introduced uncertainty about the taxonomic status of several broadly distributed and morphologically variable Placobdella species, including Placobdella picta (Verrill 1872), compounded by incomplete original descriptions reliant upon characters that are no longer unique in comparison to modern congeners. We assessed specimens of P. picta to identify any distinct phylogenetic entities that align with our morphological observations of the type series and novel topotype specimens. Using mitochondrial COI and ND1 and nuclear 18S rDNA with Maximum Likelihood and Bayesian Inference, we evaluated species boundaries using species delimitation analyses (ABGD, mPTP, bPTP, and GMYC) and molecular phylogenetics. Our analyses revealed 2 species entities equivalent to 2 non-reciprocal monophyletic clades. Morphological examinations revealed the lectotype was determined to be Placobdella ornata (Verrill 1872), and paralectotypes are other leech species or were poorly preserved and unidentifiable. Due to the problems with the type series, P. picta is now considered a junior synonym of P. ornata.
