Occurrence and Molecular Characterization of Infection in HIV/Aids Patients in Algeria.

The estimated prevalence rate of adults living with HIV infection in MENA is one of the lowest in the world. To date, no data on the genetic characteristics of isolates from HIV/AIDS patients in Algeria were available. This study aimed to identify species and subtype families prevalent in Algerian HIV-infected patients and contribute to the molecular epidemiology mapping of in the MENA region.

A summary of cryptosporidiosis outbreaks reported in France and overseas departments, 2017-2020.

is a known foodborne pathogen, ranked fifth out of 24 among foodborne parasites in terms of importance and a cause of many cryptosporidiosis outbreaks worldwide. In France, very few outbreaks were reported before 2017, and data recently obtained by the Expert Laboratory of the Cryptosporidiosis National Reference Center (CNR-LE-Cryptosporidiosis) have shown that outbreaks are in fact common and frequently underreported. In this work, we aim to report the characteristics of outbreaks detected in France during the period 2017-2020 and present a summary of investigations carried out by the CNR-LE-Cryptosporidiosis.

Genetic diversity of Cryptosporidium spp. in non-human primates in rural and urban areas of Ethiopia.

Non-Human Primates (NHPs) harbor Cryptosporidium genotypes that can infect humans and vice versa. NHPs Chlorocebus aethiops and Colobus guereza and humans have overlapping territories in some regions of Ethiopia, which may increase the risk of zoonotic transmission of Cryptosporidium. This cross-sectional study examined the molecular prevalence and subtypes of Cryptosporidium spp.

Molecular characterization of Cryptosporidium spp. from humans in Ethiopia.

Data on the distribution and genotype of Cryptosporidium species is limited in Ethiopia. This study examined the presence and genetic diversity of Cryptosporidium species circulating in Ethiopian human population. Stool samples collected from patients who visited rural (n = 94) and urban (n = 93) health centers in Wurgissa and Hawassa district, respectively, were examined for the presence of Cryptosporidium spp.

Scedosporium species in soils from various biomes in Northwestern Morocco.

Scedosporium species are opportunistic pathogens causing various infections, including disseminated infections in severely immunocompromised patients. Preventive measures aiming to reduce the risk of exposure to these fungi require a better knowledge on their ecology and on the sources of contamination of the patients. In this context, 99 soil samples from the Rabat-Sale-Kenitra and Fez-Meknes regions in Morocco were analyzed.

Long-Term Rasamsonia argillacea Complex Species Colonization Revealed by PCR Amplification of Repetitive DNA Sequences in Cystic Fibrosis Patients.

The aim of this work was to document molecular epidemiology of Rasamsonia argillacea species complex isolates from cystic fibrosis (CF) patients. In this work, 116 isolates belonging to this species complex and collected from 26 CF patients and one patient with chronic granulomatous disease were characterized using PCR amplification assays of repetitive DNA sequences and electrophoretic separation of amplicons (rep-PCR). Data revealed a clustering consistent with molecular species identification.

Semi-automated repetitive sequence-based PCR amplification for species of the Scedosporium apiospermum complex.

Purpose: The Scedosporium apiospermum species complex usually ranks second among the filamentous fungi colonizing the airways of patients with cystic fibrosis (CF), but little is known about the molecular epidemiology of the airway colonization.

Methods: Polymerase chain reaction (PCR) amplification of repetitive sequences (rep-PCR) was applied to the retrospective analysis of a panel of isolates already studied by random amplification of polymorphic DNA (RAPD) and comprising 63 isolates recovered from sputa from 9 CF patients. Results were compared to those obtained previously by RAPD, and herein by beta-tubulin (TUB) gene sequencing and Multilocus Sequence Typing (MLST).
