A total of 20 fish were collected from the Vaal River below the Vaal Dam and Lake Heritage in the Crocodile River, Gauteng, South Africa. In Lake Heritage, the prevalence of the infection was 80%, with mean intensity and mean abundance of 2.5 and 2, respectively. Perforation and alteration of the columnar epithelial cells lining the secondary folds of the stomach mucosa, trauma to the loose connective tissue, and gastric glands were observed. Mast cell numbers did not vary in the infected and uninfected samples, indicating the absence of an initiated cellular immune response. No haemorrhage, cellular infiltration, inflammation, necrosis or granuloma formation was observed in the infected sample. The peribuccal flanges, the solid buccal capsule and the muscular oesophagus are the wound\u2010inflicting and feeding structures.\n                  <\/jats:p>","DOI":"10.1111\/jfd.70107","type":"journal-article","created":{"date-parts":[[2025,12,13]],"date-time":"2025-12-13T01:06:49Z","timestamp":1765588009000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Aspects of the Histopathology of\n                    <i>Clarias gariepinus<\/i>\n                    Infected With the Camallanid Parasite\n                    <i>Procamallanus<\/i>\n                    (\n                    <i>Procamallanus<\/i>\n                    )\n                    <i>pseudolaeviconchus<\/i>\n                    Moravec and Van As, 2015"],"prefix":"10.1111","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5558-7513","authenticated-orcid":false,"given":"Thabo Kenneth","family":"Matea","sequence":"first","affiliation":[{"name":"Department of Zoology University of Johannesburg  Johannesburg South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8820-7679","authenticated-orcid":false,"given":"Annemari\u00e8","family":"Avenant\u2010Oldewage","sequence":"additional","affiliation":[{"name":"Department of Zoology University of Johannesburg  Johannesburg South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,12,12]]},"reference":[{"key":"e_1_2_12_2_1","first-page":"287","article-title":"Histopathological Study of \n                     Corydoras micracanthus\n                   (Siluriformes: Callichthyidae) Parasitized by the Nematode Procamallanus (Spirocamallanus) pintoi (Camallanidae) From Lesser River, Northwestern Argentina, South America","volume":"65","author":"Ail\u00e1n\u2010Choke L.
