“…The high prevalence of pig coccidia observed in this study (56.6%; 106/187), corroborates the results found by Sevá et al (2018), in subsistence breeding pigs in the Municipality of Teodoro Sampaio in the State of São Paulo, Brazil, which reported prevalence of coccidial oocysts in 60% of the studied pigs. Similar studies should be included here (Santos & Lopes, 1994) On the other hand, lower prevalence was obtained by Kouam et al (2018), in Bamboutos in the Republic of Cameroon, a region that has a typical climate similar to that in the Semiarid Region of Northeastern Brazil, with two main seasons, dry and rainy, in which 26.9% of pigs had coccidia infections.…”

There is great diversity in swine coccidia, which are responsible for causing intestinal disorders ranging from sporadic diarrhea to severe cases of hemorrhagic enteritis. Thus, determining the species of coccidia that affect the animals of a region and associating them with the characteristics of the farms become extremely important. The objective of this study was to determine the prevalence of coccidia parasites in pigs reared in a family farming production system in the Semiarid Region of the State of Paraíba, Northeast Brazil. Fecal samples for analysis were collected from 187 pigs on 51 farms. For morphological analysis, 1,590 sporulated oocysts were used. The prevalence of oocysts in fecal samples was 56.6% (106/187). The most prevalent species were Eimeria suis (21.9%), followed by Eimeria neodebliecki (16.6%), Eimeria perminuta (14.9%), Eimeria polita (12.8%), Eimeria debliecki (10.6%), Eimeria porci (10.1%), Cystoisospora suis (3.7%), Eimeria scabra (1.6%) and Eimeria cerdonis (0.5%). It can be concluded that pigs from the Semiarid Region of the State of Paraíba were parasitized by a diversity of coccidia species, mainly of the genus Eimeria, and predominantly presented with mixed infections occurring in the subclinical form.

Cryptosporidium spp. is a pathogenic protozoan present in the gastrointestinal tract of several hosts. This protozoan was originally classified as within the Coccidia Class and has recently been reclassified to gregarine based on studies that observed the evolutionary phases from the process of excision and sequencing of the 18S rRNA gene. Molecular biology techniques have become diagnostic tools and have also been used to understand the epidemiology of Cryptosporidium spp., since several species of this genus are very similar morphologically and morphometrically. Molecular techniques have been used in the identification of parasites, at the species and subtypes levels and to study disease transmission. The laboratory diagnosis of human cryptosporidiosis can be made by parasite detection methods, such as optical microscopy, antigens or genetic material detection, as well as serum antibodies raised to Cryptosporidium spp. Molecular methods were developed and allowed, not only an extensive revision of the taxonomy, but also an improvement in the laboratory diagnosis. In Brazil, there are few reports of Cryptosporidium spp. outbreaks in humans and all of them took place in nurseries. A few epidemiological studies developed in Brazil have used molecular methods for the detection of Cryptosporidium spp., as well as genotyping studies of their species and subtypes. The use of real-time PCR, together with microscopy and immunochromatography techniques, would result in a more precise diagnosis of cryptosporidiosis. The analysis of genotypes, subtypes and clonality of Cryptosporidium could be useful to understand and define the prognosis and severity of infections.

“…In rural areas with low economic income in South Africa, China, and Argentina and urban areas of Uruguay, Holland, and the Antilles, the prevalence of Ancylostoma in dogs ranges from 66–96% [3]. The prevalence of Ancylostomiasis in the feces of domestic dogs has been reported to be 54% in Brazil [20], 52.22% in Mexico [21], 13.9–52.9% in Colombia [22,23], 16.9% in Peru [24], and 13% in Argentina [25]. In the Galapagos Islands and Ecuador, the prevalence of Ancylostoma caninum is 57.7% in domestic dogs [26], and in Limoncito in the province of Guayas, it was found to be 11.29% [13].…”

Patient: Male, 8Final Diagnosis: Cutaneous larva migransSymptoms: Acute pain in the foot • itchingMedication: —Clinical Procedure: Treatment, ivermectin in a single dose of 200 μg/kgSpecialty: General and Internal MedicineObjective:Rare co-existance of disease or pathologyBackground:Cutaneous larva migrans (CLM) is caused by nematode parasites of the hookworm family of Ancylostomatidae. Ancylostomiasis is a zoonosis found in cats and dogs, and humans are an accidental host. This report presents a case of CLM in an 8-year-old boy, which was due to the zoonotic transmission of Ancylostoma caninum from domestic dogs in an urban area of Vinces, Ecuador, and demonstrates how awareness and early diagnosis contributed to the timely treatment of CLM.Case Report:An 8-year-old boy from the urban area of Vinces city in the Los Ríos province of Ecuador presented with a serpiginous palpable lesion on the sole of the right foot, consistent with a diagnosis of cutaneous larva migrans (CLM). He was infected through contact with the soil where canine Ancylostoma larvae were found. Twenty samples of feces were analyzed from the soil, and Ancylostoma larvae were found in 100% of these samples. Also, 120 dog stool samples were examined, and 75 (62.5%) contained Ancylostoma larvae, which were identified using the modified Willis and Baermann method.Conclusions:CLM is a zoonotic disease that can affect the population in endemic areas. In this case, CLM was identified in the sole of the foot of a child. The presence of Ancylostoma larvae were identified in the soil and in the feces of dogs, indicating that the community was exposed to a significant environmental risk from this zoonotic disease.
