Although Ascaris lumbricoides is a common intestinal parasite of humans with worldwide distribution causing ascariasis, Ascaris is a neglected disease and still is a burden in developing countries. Furthermore, the parasite’s permanence and prevalence present difficulties in control strategies. Therefore, more research on the mechanisms of resistance to infection is required for reducing prevalence parasite and control of infections.

Coronavirus (CoV) (2019‐nCoV) is a large, enveloped, positive-sense, single-stranded RNA virus. The abnormal outbreak of 2019‐nCoV in Wuhan warns of the risk of CoV (2019‐nCoV) to public health which causes viral pneumonia outbreak. In our review, we will discuss the biology of CoVs and the potential risk of the novel CoV (2019‐nCoV) and guide us to strategic objectives for controlling the virus.

Lymphatic filariasis (LF) is a tropical disease caused by infection with the parasitic filarial worms: Wuchereria bancrofti, Brugia malayi, and Brugia timori. The symptoms of this chronic disease appear in adults (in men more than in women) and include damage to the lymphatic system, arms, legs, and genitals, which cause significant pain, reducing productivity, and social problems. LF is a cause of continued disability, pain, disfigurement, and sexual disability in the world, so the knowledge of the disease and the infection control is very important. In addition to the importance of prevention, that includes giving medicine and using controlling ways of mosquitoes. Moreover, the prevention of disease is important, that includes giving medicine and using controlling ways of mosquitoes. However, although the efforts of health organizations to reduce the LF infections, there are still many challenges including the early diagnosis and control of infection among people.

Listeria monocytogenes is nonspore-forming, gram-positive rods, it is a widespread bacterium; it can survive for a long time in different environments such as food, soil, water, and feces causing adverse health impacts in both animals and humans. Because of its pathogenesis mechanism combined with its ubiquity, It's considereda serious concern. Invasive listeriosis could be without symptoms until 1-4 weeks after infection. It causes serious complications especially in pregnant women, newborn babies, and people with weakened immunity if left untreated. An example of its outbreak what happened in South Africa in January 2018, which resulted in 180 deaths. Attention is conferred on L.monocytogene from being able to adapt to many types of stresses. Moreover, it can activate specific genes during the life cycle allowing it to replicate within many host cell types during its infection. In our review, we will highlight the pathogenicity of L.monocytogenes, with emphasis on its antimicrobial resistance.

The study was conducted with the aim of detecting intestinal helminth infection in those living in Lattakia Governorate, and to determine their species and prevalence through laboratory screening of stool samples for patients visiting the Microbiology Laboratory at Tishreen University Hospital -Lattakia during the years 2016 -2017.By investigating the presence of eggs in the stool samples, the results of the laboratory tests conducted on the stool samples showed a prevalence of helminth infection in the intestinal tract in the population of Lattakia. Seven species of intestinal parasitic worms were recorded due to the patients examined: 3 Species of Nematoda (Enterobius vermicularis, Ascaris lumbricoides, and Ancylostoma duodenale), and 4 Species of Platehelminthes: two species belong to the class Trematoda: Class: Paragonimus Westermani and Schistosoma mansoni, and two cases belonging to the class Cestoda: Hymenolepis nana. This study has recorded, for the first time, the infection with Ancylostoma duodenale and Schistosoma Mausoni in Syria.The overall prevalence of intestinal helminth infection was reported in patients who were referred to the Microbiology laboratory in Lattakia during the years 2016-2017 was 3.77%. The vast majority of those infected with only one species of intestinal worms, while registered two cases of infection multiplier: Ascaris lumbricoides and Enterobius Vermicularis.The study showed that Enterobius Vermicularis is the most common intestinal worms in the population in Lattakia (13.2%), followed by the Ascaris lumbricoides, then the stalagmites. The prevalence of intestinal helminth infection in Lattakia was higher among males than females, and prevalence of intestinal helminthiasis was highest in winter and autumn of 2016-2017.
