Abstract
PURPOSE Cryptosporidium is an intestinal zoonotic protozoan parasite that infects domesticated and wild animals. There are no reports on the prevalence and molecular characterisation of Cryptosporidium in the endemic Cyprus mouflon. The mouflon is strictly protected by national and international legislation. Its main distribution is Paphos State Forest and surrounding areas, where it may share the same water sources as free-ranging domestic goats. Therefore, the present study aimed to determine the prevalence of Cryptosporidium spp. and genotypes in mouflon and free-ranging goats within the mouflon range. METHODS Faecal samples of 70 mouflons and 34 free-ranging goats were screened for Cryptosporidium by PCR amplification and sequencing. RESULTS Only one sample (1/70) belonging to a mouflon was PCR positive for Cryptosporidium. Based on sequencing of the 18S rRNA locus, this species was identified as Cryptosporidium parvum (C. parvum). No positive sample was detected in the free-ranging goats (0/34). CONCLUSION This is the first report on the molecular identification of this Cryptosporidium species in a Cyprus mouflon. The results indicate that the prevalence of Cryptosporidium in Cyprus mouflon is low.

Abstract
The current study presents a comprehensive review of worldwide waterborne parasitic protozoan outbreaks reported between 2017 and 2022. In total, 416 outbreaks were attributed to the waterborne transmission of parasitic protozoa. Cryptosporidium accounted for 77.4% (322) of outbreaks, while Giardia was identified as the etiological agent in 17.1% (71). Toxoplasma gondii and Naegleria fowleri were the primary causes in 1.4% (6) and 1% (4) of outbreaks, respectively. Blastocystis hominis, Cyclospora cayetanensis, and Dientamoeba fragilis were independently identified in 0.72% (3) of outbreaks. Moreover, Acanthamoeba spp., Entamoeba histolytica, Vittaforma corneae, and Enterocytozoon bieneusi were independently the causal agents in 0.24% (1) of the total outbreaks. The majority of the outbreaks (195, 47%) were reported in North America. The suspected sources for 313 (75.2%) waterborne parasitic outbreaks were recreational water and/or swimming pools, accounting for 92% of the total Cryptosporidium outbreaks. Furthermore, 25.3% of the outbreaks caused by Giardia were associated with recreational water and/or swimming pools. Developing countries are most likely to be impacted by such outbreaks due to the lack of reliable monitoring strategies and water treatment processes. There is still a need for international surveillance and reporting systems concerning both waterborne diseases and water contamination with parasitic protozoa.

Abstract
We report the off-label use of a commercial gastrointestinal protozoa multiplex-PCR panel for bronchoalveolar lavage samples, detecting respiratory cryptosporidiosis in 2 immunocompromised pediatric patients. We suggest that implying this readily available assay in cases in which systemic cryptosporidiosis is suspected, may widen our understanding regarding this rarely reported syndrome.

Abstract
Cryptosporidium parvum is the second-most prevalent Cryptosporidium species that infects humans worldwide. In European countries, it is the most prevalent species in sheep, suggesting that these animals are a source of zoonotic infection. Preweaned lambs and goats are particularly susceptible to infection by the parasite and may suffer from severe diarrhea whilst excreting large quantities of infectious oocysts. Fifty fecal samples from preweaned lambs and goats with diarrhea from 35 farms across Israel, found to be Cryptosporidium-positive by microscopy, were tested by PCR and sequence analyses to determine the infective species and subtypes. Cryptosporidium parvum DNA was detected in most samples from both lambs and goats (46/50). Cryptosporidium xiaoi DNA was detected in three samples from kids, with co-infection detected in a single sample. Eleven different C. parvum subtypes were found, 10 in lambs and 5 in goats. All subtypes were from the IIa and IId subtype families, with subtypes IIdA20G1 and IIaA15G2R1 being the most prevalent and widespread. These subtypes were previously found in calves and humans in Israel and are considered the most prevalent C. parvum subtypes in small ruminants globally. These results underline the zoonotic potential of C. parvum from small ruminants and the high subtype diversity compared to previous reports from other Middle Eastern countries. In addition, this is the first report of C. xiaoi in Israel.

Abstract
BACKGROUND We aimed to investigate the prevalence of Cryptosporidium species detected in humans and calves in the Van region of Turkey. METHODS A total of 150 patients, comprising 60 who were immunosup-pressed, 50 who were immunosuppressed and had diarrhea, and 40 who had only diarrhea, were enrolled in this study in the Department of Medical Parasitology, Van Yuzuncu Yıl University Faculty of Medicine, Turkey. Stool samples were taken from the rectums of a total of 50 calves that had 30 diarrhea and 20 that did not have diarrhea, from the stables and farms of 10 central villages of Van, Turkey. All samples were analyzed using modified acid-fast staining, immunochromatographic test, and PCR. Cryptosporidium positive samples were also subtyped. RESULTS Only C. parvum subtypes were detected in all positive samples. C. parvum was detected in 30 (20%) of the 150 human stool samples, while it was detected in 5 (10%) of the 50 samples from the calves. The GP60 gene region was amplified and sent for sequence analysis to identify the C. parvum subtypes. CONCLUSION As a result, C. parvum is found to be an active species that caused cryptosporidiosis is in the Van region. IIdA24G1 subtype of C. parvum were found in both human and calf. Therefore, due to the zoonotic feature of the C. parvum IIdA24G1 subtype, it has been shown that the calves in the region are a significant risk for humans.

Abstract
Background: Cryptosporidium spp. are pathogenic protozoans that play an important role in developing diseases in the elderly, children, and immunosuppressed individuals. Methods: The objective of this study was to detect and genetically characterize Cryptosporidium spp. in kidney transplanted patients (n = 97 samples; group 1) and immunosuppressed individuals from an outpatient clinic suspected of having Cryptosporidium infection (n = 53 samples; group 2). All fecal samples were analyzed by parasitological stool examination, immunochromatographic test, and real-time polymerase chain reaction (real-time PCR). Cryptosporidium-positive samples were tested using nested PCR for the gp60 gene, followed by sequencing for subtype determination. Results: Parasitological examination was negative in all Group 1, and positive in four Group 2 samples. Real-time PCR revealed Cryptosporidium in 13 samples: four in Group 1 (three C. hominis and one C. parvum) and nine in Group 2 (seven C. hominis, one C. parvum, and one mixed C. hominis/C. parvum). The immunochromatographic test was reactive in 11 samples (four in Group 1 and seven in Group 2). All 11 C. hominis isolates were identified as subtype IbA10G2 and one C. parvum as subtype IIbA15G2R1. All C. hominis belonged to subtype IbA10G2, which is recognized as the most prevalent and pathogenic subtype. Conclusions: This study showed, for the first time, that the presence of Cryptosporidium subtypes is considered more virulent in Brazilian transplanted kidney patients.

Abstract
Cryptosporidium spp. and Giardia duodenalis are important protozoan parasites which are associated with diarrheal diseases in humans and animals worldwide. Relatively little is known about the molecular epidemiology of Cryptosporidium spp. and Giardia duodenalis in the Middle East Countries and North Africa (MENA region). Therefore, this review aimed to inspect published genotyping and subtyping studies on Cryptosporidium spp. and Giardia duodenalis in the MENA region. These studies indicate that both anthroponotic and zoonotic transmission of Cryptosporidium occurs with the predominance of zoonotic transmission in most countries. Seven Cryptosporidium species were identified in humans (C. parvum, C. hominis, Cryptosporidium meleagridis, C. felis, Cryptosporidium muris, C. canis and C. bovis), with C. parvum by far being the most prevalent species (reported in 95.4% of the retrieved studies). Among C. parvum gp60 subtype families, IIa and IId predominated, suggesting potential zoonotic transmission. However, in four MENA countries (Lebanon, Israel, Egypt and Tunisia), C. hominis was the predominant species with five subtype families reported including Ia, Ib, Id, If and Ie, all of which are usually anthroponotically transmitted between humans. In animals, the majority of studies were conducted mainly on livestock and poultry, 15 species were identified (C. parvum, C. hominis, C. muris, Cryptosporidium cuniculus, C. andersoni, C. bovis, C. meleagridis, C. baileyi, C. erinacei, C. ryanae, C. felis, C. suis, Cryptosporidium galli, C. xiaoi and C. ubiquitum) with C. parvum (IIa and IId subtypes) the dominant species in livestock and C. meleagridis and C. baileyi the dominant species in poultry. With G. duodenalis, five assemblages (A, B, C, E and F) were identified in humans and six (A, B, C, E, D and F) in animals in MENA countries with assemblages A and B commonly reported in humans, and assemblages A and E dominant in livestock. This review also identified a major knowledge gap in the lack of Cryptosporidium spp. and Giardia duodenalis typing studies in water and food sources in the MENA region. Of the few studies conducted on water sources (including drinking and tap water), ten Cryptosporidium species and four genotypes were identified, highlighting the potential role of water as the major route of Cryptosporidium spp. transmission in the region. In addition, three G. duodenalis assemblages (A, B and E) were detected in different water sources with AI, AII and BIV being the main sub-assemblages reported. More research is required in order to better understand the molecular diversity and transmission dynamics of Cryptsporidum spp. and Giardia duodenalis in humans, animals, water and food sources in MENA region.

Abstract
Cryptosporidium species are responsible for causing the majority of parasite-related gastrointestinal infections in the UK. This report describes an outbreak of 12 laboratory-confirmed cryptosporidiosis cases identified as part of a Scottish swimming pool investigation, with 9 primary and 3 secondary cases occurring over an 8-week period. Molecular speciation was successful for 11/12 cases, which revealed 10 Cryptosporidium hominis cases and 1 Cryptosporidium parvum case. Of the 10 C. hominis cases, further typing identified 7 as being an unusual sub-type, IbA6G3, which is the first description in the UK of this rare variant. The remaining three C. hominis cases were identified as the common IbA10G2 subtype. Following implementation of control measures on two occasions, no further cases were reported. This report highlights the importance of molecular typing to identify and characterize outbreaks, and emphasizes the need to adhere to swimming pool guidance. It also raises awareness of the potential for outbreaks to involve multiple species/sub-types, and emphasizes the importance of strong public health leadership to ensure effective multi-agency investigations and management of outbreaks.
