Two species are responsible for most cases: <i>Cryptosporidium hominis (C. hominis)</i> and <i>Cryptosporidium parvum</i> (<i>C. parvum</i>). Transmission occurs faecal-orally, through ingestion of contaminated food and water, or direct contact with faeces. In 2020, the COVID-19 pandemic led to global restrictions, including national lockdowns to limit viral transmission. Such interventions led to decreased social mixing, and reduced/no local and international travel, which are factors associated with transmission of multiple communicable diseases, including cryptosporidiosis. This report assessed the impact of the pandemic on Scottish cryptosporidiosis cases, and identified changes in circulating molecular variants of <i>Cryptosporidium</i> species. Molecular data generated using real time PCR and GP60 nested-PCR assays on laboratory-confirmed cryptosporidiosis cases reported during 2018-22 were analysed. The Scottish Microbiology Reference Laboratories (SMiRL), Glasgow, received 774 <i>Cryptosporidium</i>-positive faeces during 2018-22, of which 486 samples were successfully subtyped. During this time period, <i>C. hominis</i> (<i>n</i> = 155; 21%) and <i>C. parvum</i> (<i>n</i> = 572; 77%) were the most commonly detected species. The total number of cases during 2020, which was greatly affected by the pandemic, was markedly lower in comparison to case numbers in the 2 years before and after 2020. The most predominant <i>C. hominis</i> family detected prior to 2020 was the Ib family which shifted to the Ie family during 2022. The most common <i>C. parvum</i> variant during 2018-22 was the IIa family, however a rise in the IId family was observed (<i>n</i> = 6 in 2018 to <i>n</i> = 25 in 2022). The dominant <i>C. hominis</i> subtype IbA10G2, which accounted for 71% of <i>C. hominis</i> subtypes in 2018-19 was superseded by three rare subtypes: IeA11G3T3 (<i>n</i> = 15), IdA16 (<i>n</i> = 8) and IbA9G3 (<i>n</i> = 3) by 2022. Frequently reported <i>C. parvum</i> subtypes in 2018-19 were IIaA15G2R1 and IIaA17G1R1, accounting for 59% of total <i>C. parvum</i> subtypes. By 2022, IIaA15G2R1 remained the most common (<i>n</i> = 28), however three unusual subtypes in Scotland emerged: IIdA24G1 (<i>n</i> = 7), IIaA16G3R1 (<i>n</i> = 7) and IIaA15G1R2 (<i>n</i> = 7).

Survival from colorectal cancer is significantly dependent on the stage at diagnosis, with the 5-year rate at ~90% for localized disease, 70% for regional disease and 13% for distantly metastatic disease [2]. Several screening tests, including faecal occult blood test and colonoscopy, are frequently used in the detection of colorectal cancer. However, none are established and well-accepted screening tools due to their invasiveness, high cost or low sensitivity [3]. Therefore, the search for more sensitive, easily detected and representative biomarkers is of great significance for the early diagnosis and monitoring of this disease. Several biological and clinical hallmarks indicate that rectal cancer is different from colon cancer. The rectum and colon have a different embryological origin, anatomy and function [4]. Consequently, the treatments for primary rectal and colon cancer are different. Primary rectal cancer requires specific surgical treatment: total mesorectal excision, preceded by neoadjuvant radiotherapy or chemoradiotherapy [5]. Despite a substantial rise in survival over the last two decades, the 5-year diseasespecific overall survival rate is approximately 59% for colon cancer and 61% for rectal cancer [6]. This indicates that it is very important to explore the difference between colon cancer and rectal cancer. Tumour markers are widely useful in the management of patients with tumours. Serum carcinoembryonic antigen (CEA) and cancer antigen 19–9 (CA19-9) are the most commonly used indexes in the clinical diagnosis of colorectal cancer, but both are non-specific. CEA is a glycoprotein produced by columnar and goblet cells in the normal colon cells, as well as colonic cancer cells with a half-life of 3–11 days. CA19-9 is also a glycoprotein with high molecular weight, which may be detected in the blood of gastrointestinal cancer patients [7]. We hypothesized different expressions of CEA, CA19-9, alpha-fetoprotein (AFP), cancer antigen 72–4 (CA72-4) and cancer antigen 125 II (CA125 II) between colon cancer and rectal cancer, hoping to provide reference for the different pathogenesis and treatment of these diseases. Of 219 patients with histopathologically confirmed colorectal cancer, 114 had colon cancer and 105 rectal cancer. There was no significant difference in age and gender between the colon cancer group and rectal cancer group (table 1). Five mL peripheral blood was extracted from a peripheral vein, and serum isolated by centrifugation at 2000× g for 15 min. Serum CA19-9, AFP, CA72-4 and CA125 II levels were determined by radioimmunoassay (Roche Diagnostics, Indianapolis, IN, USA), with a normal upper limit of 37 U/ml, 7 ng/ml, 6.9 U/ml and 35 U/ml, respectively. The serum CEA level was determined by ELISA (Dinabot, Tokyo, Japan), with a normal upper limit of 5 ng/ml.
