The Histopathology of Antique Ark's Mantle (Anadara Antiquata) Post
The histopathology of antique ark’s mantle (Anadara antiquata) post-depuration with the shells’ filtration Nabila A. Putri, Laksmi Sulmartiwi, Kustiawan T. Pursetyo Faculty of Fisheries and Marine, Universitas Airlangga, 60115, Surabaya, Indonesia. Corresponding author: L. Sulmartiwi, [email protected] Abstract. Cockles are marine organisms which have the character of filter feeders so that heavy metals can be neutralized naturally through their shells. However, not all heavy metals can be neutralized, so depuration needs to be done. After depuration, histopathological analysis is needed to determine the condition of the soft tissue of the shells so that the disease can be diagnosed through structural changes that occur in the organs that are the main target of pollutants. This study aims to determine the histopathology of antique ark’s mantle (Anadara antiquata) after post-depuration with the filtration of the cockles’ shells. This research method applies an experimental method with scoring histological damage to antique ark’s mantle that ranges from 0 to 3, depending on the level and extent of the changes that occur. After that, the distribution of normal and non-homogeneous data was obtained, and then the Kruskal-Wallis non-parametric test was conducted. The main parameter is the histopathology of the antique ark’s mantle. Supporting parameters include water quality, namely temperature, dissolved oxygen (DO), nitrate, nitrite, ammonia, salinity, levels of heavy metals Pb and Cd, total suspended solid (TSS) and total dissolved solid (TDS). The results of the Kruskal-Wallis statistical analysis shows no significant difference between treatments P0 (Control), P1 (Filter 25%), P2 (Filter 50%), P3 (Filter 75%), and P4 (Filter 100%). -

This novel coccidian is unusual because it develops extra-intestinally and sporulates endogenously within the prostate gland of its mammalian host. Histological examination of prostatic tissue revealed dense aggregations of spherical and thin-walled tetrasporocystic, dizoic sporulated coccidian oocysts within tubular lumina, with unsporulated oocysts and gamogonic stages within the cytoplasm of glandular epithelial cells. This coccidian was observed occurring concurrently with dasyurid herpesvirus 1 infection of the antechinus' prostate. Eimeria- specific 18S small subunit ribosomal DNA PCR amplification was used to obtain a partial 18S rDNA nucleotide sequence from the antechinus coccidian. -

The Intestinal Protozoa
The Intestinal Protozoa A. Introduction 1. The Phylum Protozoa is classified into four major subdivisions according to the methods of locomotion and reproduction. a. The amoebae (Superclass Sarcodina, Class Rhizopodea move by means of pseudopodia and reproduce exclusively by asexual binary division. b. The flagellates (Superclass Mastigophora, Class Zoomasitgophorea) typically move by long, whiplike flagella and reproduce by binary fission. c. The ciliates (Subphylum Ciliophora, Class Ciliata) are propelled by rows of cilia that beat with a synchronized wavelike motion. d. The sporozoans (Subphylum Sporozoa) lack specialized organelles of motility but have a unique type of life cycle, alternating between sexual and asexual reproductive cycles (alternation of generations). e. Number of species - there are about 45,000 protozoan species; around 8000 are parasitic, and around 25 species are important to humans. 2. Diagnosis - must learn to differentiate between the harmless and the medically important. This is most often based upon the morphology of respective organisms. 3. Transmission - mostly person-to-person, via fecal-oral route; fecally contaminated food or water important (organisms remain viable for around 30 days in cool moist environment with few bacteria; other means of transmission include sexual, insects, animals (zoonoses). B. Structures 1. trophozoite - the motile vegetative stage; multiplies via binary fission; colonizes host. 2. cyst - the inactive, non-motile, infective stage; survives the environment due to the presence of a cyst wall. 3. nuclear structure - important in the identification of organisms and species differentiation. 4. diagnostic features a. size - helpful in identifying organisms; must have calibrated objectives on the microscope in order to measure accurately. -
Freshwater Crayfish Cherax Quadricarinatus
DISEASES OF AQUATIC ORGANISMS Vol. 41: 115-122,2000 Published June 19 Dis Aquat Org l Infectivity, transmission and 16s rRNA sequencing of a rickettsia, Coxiella cheraxi sp. nov., from the freshwater crayfish Cherax quadricarinatus C. K. Tan, L. Owens* Department of Microbiology and Immunology. James Cook University, Townsville 4811, Australia ABSTRACT: A rickettsia-like organism isolated from infected, farm-reared Cherax quadricarinatus was cultured in the yolk sac of developing chicken eggs, but could not be cultured in 3 continuous cell lines, bluegill fry (BF-2),fathead minnow (FHM),and Spodoptera frugiperda (Sf-9).The organism was confirmed by fulfilling Koch's postulates as the aetiological agent of mortalities amongst C, quadricar- inatus. When C. quadricarinatus was inoculated with the organism, mortality was 100% at 28°C and 80% at an ambient temperature of 24°C. Horizontal transmission with food and via the waterborne route was demonstrated, but mortalities were lower at 30 and 10% respectively over a 4 wk period. The 16s rRNA sequence of 1325 base pairs of the Gram-negative, obligate intracellular organism was 95.6% homologous to Coxiella burnetii. Of 18 species compared to this rickettsia, the next most closely related bacterium was Legionella pneumophila at 86.7 %. The suggested classification of this organism is Order Rickettsiales, family Rickettsiaceae, tribe Rickettsieae, within the genus Coxiella. We suggest it should be named Coxiella cheraxi sp. nov.
